As such, a consecutive di-SN2 reaction between dithiols and polyhalogenated compounds was used to produce degradable polymers with tunable amounts of redox-enabled dithioacetal and disulfide linkages. The reaction employed bases of varying strengths and different thiol types, allowing for control over molecular weights ranging from <1 kDa to 16 kDa, with tunable degrees of polymerization ranging from 3 to over 75. The ratio of dithioacetals to disulfides was adjusted by manipulating the concentration of the methylene source, enabling the formation of polymers with up to 100% disulfide linkages or up to 93% dithioacetal linkages. This tunability resulted in polymers with multiple redox degradation pathways, capable of being degraded by either reduction or oxidation. Vinyl ether functionalized, telechelic oligomers were used as crosslinkers in network formation, yielding materials with multiple degradation pathways.

  @article{ , abstract = {One-step purification of ethylene (C 2 H 4 ) from the ternary mixtures of acetylene/carbon dioxide/ethylene (C 2 H 2 /CO 2 /C 2 H 4 ) is a critical industrial challenge due to their similar physical and chemical properties. Herein, we reported a cage engineering strategy in anion-pillared metal-organic frameworks (APMOFs) for efficient C 2 H 2 and CO 2 capture simultaneously. Specifically, two stable ZrF 6 2− anion-pillared cage-type MOFs (ZNU-17 and ZNU-27) are prepared with both ultramicroporous (∼4 Å) and microporous (>7 Å) cages but featuring different shapes. While ZNU-17 allows the efficient binary C 2 H 2 /C 2 H 4 separation, ZNU-27 enables the benchmark ternary C 2 H 2 /CO 2 /C 2 H 4 separation by increasing the adsorption affinity toward CO 2 . Notably, remarkably increased C 2 H 2 (170.1 cm 3 g −1 versus 120.1 cm 3 g −1 ) and CO 2 (91.8 cm 3 g −1 versus 64.5 cm 3 g −1 ) adsorption capacities are achieved in ZNU-27, and the IAST selectivity of ZNU-27 for CO 2 /C 2 H 4 is 4.3 times as high as that of ZNU-17 (6.5 versus 1.5). The C 2 H 2 , CO 2 and C 2 H 4 binding sites in ZNU-27 are studied by gas loaded in situ single crystal structure and density functional theory (DFT) calculation, which revealed that the unique fluorinated 8.5 Å spherical cages provide strong hydrogen binding or electrostatic interactions for C 2 H 2 and CO 2 . Dynamic breakthrough tests show that from a C 2 H 2 /CO 2 /C 2 H 4 (1/9/90) mixture, polymer-grade C 2 H 4 (≥99.99%) can be obtained in ZNU-27 with a high productivity of 12.04 mol kg −1 .}, archive = {J_ANGEW}, author = {Lingyao Wang and Huirong Chen and Chengye Lou and Guangzu Xiong and Yunjia Jiang and Banglin Chen and Yuanbin Zhang}, doi = {10.1002/anie.202514808}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {40}, pages = {e202514808}, shortjournal = {Angew.

  @article{ , abstract = {Electrochemical synthesis has emerged as a sustainable platform in constructing C─N bonds for amino acid production. Glycine, a particularly valuable target compound, continues to experience escalating global demand, yet achieving simultaneous high efficiency and operational stability remains a persistent challenge. Herein, we demonstrate a CO 2 -mediated strategy for glycine electrosynthesis using oxalic acid and N 2 /nitrate as feedstocks. By using Pb/Pb 7 Bi 3 -CO 2 catalytic system, a very high glycine Faradaic efficiency (FE) of 91.8% with durable stability over 120 h could be achieved. Moreover, when using nonthermal plasma-activated N 2 as the nitrogen source, the glycine production rate could maintain at 94.4 µmol h −1 cm −2 with N-selectivity as high as 93.2%. Mechanistic investigations combining experiments and theoretical calculations reveal that CO 2 undergoes facile protonation on the Pb/Pb 7 Bi 3 heterointerfaces to form * OCOH intermediate, which donates hydrogen for the reduction of oxalic acid and nitrate into glyoxylic acid and NH 2 OH, respectively, while CO 2 is simultaneously regenerated. Notably, hydrogenation via the * OCOH intermediate significantly lowers the energy barriers compared to direct protonation, thereby promoting the subsequent spontaneous C─N bond formation and enabling highly efficient electrosynthesis of glycine.}, archive = {J_ANGEW}, author = {Pengsong Li and Yong Wang and Xiangda Zhang and Congyang Wang and Yuqing Hou and Ganwen Zhang and Xihua Wang and Lihong Jing and Qingli Qian and Xinchen Kang and Xiaofu Sun and Qinggong Zhu and Buxing Han}, doi = {10.1002/anie.202514321}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {40}, pages = {e202514321}, shortjournal = {Angew.

• (2025). Extending the chemistry of scheelite-type oxides with borates. ANGEW, 64(40), e202514159. (www)

  @article{ , abstract = {Scheelite-type oxides have been extensively investigated in diverse inorganic systems due to their exceptional structural versatility and promising multifunctional properties, ranging from luminescence to ionic conduction. However, despite decades of research, borates have remained conspicuously absent from this important structural family. This exclusion stems from a fundamental synthetic and structure chemistry challenge: the difficulty in achieving the essential zero-dimensional anionic framework composed of isolated tetrahedral units, a defining characteristic of scheelite-type materials. In this work, we break this long-standing barrier by reporting the first successful isolation of [BO 2 F 2 ] tetrahedra in a crystalline solid. This breakthrough was enabled by employing Sb's stereochemically active lone pair electrons to stabilize these discrete [BO 2 F 2 ] units, ultimately leading to the discovery of SbBO 2 F 2 —the first borate compound adopting a scheelite-type structure. Through a combination of single-crystal X-ray diffraction, spectroscopic techniques, and first-principles calculations, we unequivocally confirm the scheelite-type framework of SbBO 2 F 2 and demonstrate its remarkable multifunctional properties, including anisotropic thermal expansion, ionic conductivity, and large birefringence.

  @article{ , abstract = {β-Amino acids are essential building blocks in bioactive molecules, offering unique properties and potential in peptide and drug synthesis. Among them, β 2,2,3 -amino acids—characterized by a contiguous quaternary and tertiary stereocenter—represent a structurally unique subclass with promising biological potential. However, their broader application has been hampered by the scarcity of general and efficient synthetic methods. To address these challenges, we have developed a visible-light-driven radical-radical coupling strategy enabled by chiral phosphoric acid (CPA) catalysis. In this synergistic dual catalytic system, β-keto esters are activated by CPA and undergo single-electron oxidation to generate tertiary carbon radicals, while redox-active NHPI esters derived from α-amino acids are reduced via SET to form α-amino alkyl radicals. Under the chiral environment provided by CPA, these radicals engage in highly selective cross-coupling to afford β 2,2,3 -amino esters in good yields with excellent diastereo- and enantioselectivity. This strategy provides a mild, modular approach for the stereo-controlled assembly of structurally complex β 2,2,3 -amino esters, overcoming long-standing limitations in substrate scope and reaction efficiency. Beyond its synthetic utility, this method offers new opportunities for expanding the chemical space of β-amino acid derivatives and holds promise for advancing medicinal chemistry and peptide-based drug discovery.}, archive = {J_ANGEW}, author = {Zi-Wei He and Bao-Ru Yuan and Xiao-Ye Yu and Min Jiang and Jia-Rong Chen and Wen-Jing Xiao}, doi = {10.1002/anie.202514155}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {40}, pages = {e202514155}, shortjournal = {Angew.

  @article{ , abstract = {Bulk water serves as an inert environment for lignin linkages, resulting in their natural half-lives that extend over centuries. In this study, we present the striking results of the spontaneous and ultrafast C─O/C─C bond cleavage of various lignin models in water microdroplets, yielding value-added aromatic chemicals. The β-O-4 linkages, the most abundant interunit linkages in natural lignin, were selectively cleaved at C β ─O bonds, producing phenols in yields exceeding 70%. Mechanistic studies elucidated that the cleavage of β-O-4 linkages is derived from the unique alkaline environment at the air–water interface of a negatively charged water microdroplet, even in the absence of extra alkalis. The challenging cleavage of the highly stable C α ─C β bonds in β-O-4 and β-1 lignin linkages was also accomplished, yielding valuable benzoic acid product. Mechanistic investigations revealed that the oxidation of the substrates by molecular oxygen is the key step for the C α ─C β bond cleavage. Notably, all intermediates, including the fragile peroxide intermediates, were identified using mass spectrometry. Accompanied by evidence from radical scavenging and 18 O labeling, the mechanisms for the selective C─O/C─C bond cleavages have been unambiguously characterized, paving a new and green way for the cleavage of lignin linkages.}, archive = {J_ANGEW}, author = {Ting Wang and Hong-Yuan Chen and Jing-Juan Xu and Jun Hu}, doi = {10.1002/anie.202514150}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {40}, pages = {e202514150}, shortjournal = {Angew.

  @article{ , abstract = {Lytic polysaccharide monooxygenases (LPMOs) are Cu-containing enzymes that play a crucial role in lignocellulosic biomass degradation for use in biofuel production. These enzymes carry out the selective oxidation of C─H bonds in the sugar units, leading to the cleavage of the glycosidic bond. Creating LPMO mimics facilitates the study of the mechanism of action, the characterisation of the reactive species responsible for the C─H bond activation and the potential scale up for industrial application. Here, we report the design, structural and functional characterisation of two novel Cu-binding β-hairpin peptides, called HisPins, that mimic the Histidine-brace site of LPMOs. Activity assays were conducted with p-nitrophenyl-β-d-glucopyranoside (PNPG) and demonstrate that the Cu-HisPins show LPMO-like activity on the model substrate. Furthermore, the Cu-HisPins can also perform light-driven oxidation of phosphoric acid swollen cellulose (PASC) in the presence of melanin, similarly to some LPMO enzymes. Hence, the Cu-HisPins represent the first structural and functional LPMO mimics based on short, folded peptide sequences and show a light-stimulated melanin-mediated oxidative activity, which is unreported for any LPMO mimic characterised so far.

In situ electrochemical spectroscopy and theoretical calculations underscore that the Co atoms within the POM serve as active sites and facilitate the rate-determining step of *OOH formation. Moreover, an anion exchange membrane water electrolyzer employing POM-CTAB-Co as the anode and Pt/C as the cathode demonstrates exceptional performance, delivering a current density of 2 A cm −2 at a cell voltage of 2.247 V, along with remarkable durability exceeding 2000 h at an industrial-grade current density of 500 mA cm −2 .

  @article{ , abstract = {Carbonyl-containing organic electrodes have been widely considered as ideal substitutes for traditional inorganic compounds in sodium-ion batteries (SIBs) due to their excellent redox reversibility and structural tunability. However, constructing effective Na + diffusion channels in these materials is very challenging. To address this issue, we design a new organic molecule, N,N ’-bis(3,4,5-trimethoxyphenyl)-1,4,5,8-naphthalenediimide (NDI-DTMA), containing a donor–acceptor–donor (D–A–D) structure. The D–A–D architecture significantly enhances π-conjugation extent of single organic material while narrowing its bandgap, facilitating electron transportation along the NDI-DTMA skeletons. Moreover, 3,4,5-trimethoxyphenyl groups not only suppress dissolution issue but also enlarge the intermolecular planar spacing for Na + mobility through constructing efficient transport channels. As an electrode material for SIBs, NDI-DTMA achieves a reversible capacity of 200 mAh g −1 after 2000 cycles at 1 A g −1 owing to its fast Na + kinetics.

The broad substrate scope includes a wide range of electron-rich, electron-deficient, and halogenated arenes, as well as heterocycles, demonstrating excellent functional group tolerance. Furthermore, the process is readily scalable, as shown by a 4-day continuous operation in parallel microreactors, producing over 100 grams of aniline product with high efficiency.

TUB41 demonstrates remarkable chemical stability across a wide pH range (1–11) and retains its structural integrity after 2 years of repeated adsorption cycles and activation at 80 °C under ambient humidity. Cryogenic adsorption experiments reveal that TUB41's pores selectively exclude gases with larger kinetic diameters, such as N 2 and Ar, while accommodating smaller molecules like CO 2 and H 2 O at elevated temperatures. The enthalpies of adsorption for CO 2 at a loading 0.01 mmol g −1 and H 2 O at a loading of 0.7 mmol g −1 are −41 and −38 kJ mol −1 , respectively, reflecting their strongly attractive interactions with TUB41 under different conditions. Molecular dynamics simulations reveal that CO 2 molecules adopt ordered arrangements in the central hydrophobic regions of the pores, guided by strong nonbonding interactions, while H 2 O molecules preferentially bind to the hydrophilic secondary building units. Mean-squared displacement analyses confirm that both gases remain spatially constrained within the pores.

The fluorine···π effect concentrates the alkyne via its adsorption enhancement, promotes electron transfer, and lowers the activation energy, thus accelerating hydrogenation kinetics. Under the bias potential, the side chain of Nafion undergoing rearrangement from disordered to nearly ordered significantly decreases the interfacial free water coverage and activity, thereby reducing the amount of in situ-generated surface-active hydrogen, which contributes to suppressing hydrogen evolution and improving the FE. An 82% FE and 18.9 mmol h −1 reaction rate of MBE is achieved in a 10 h continuous electrosynthesis at 1.25 A, demonstrating potential utility.

Herein, a Taiji-inspired dual-electrode stabilization strategy is developed to synergistically regulate interfacial chemistry at both electrodes, enabling durable high-areal-capacity Zn-Br 2 batteries. This design leverages the dynamic balance of opposing yet complementary electrostatic interactions, facilitating targeted attraction (Yin) and repulsion (Yang) of polybromides at cathode/anode interfaces, respectively. At the cathode, positively charged quaternary ammonium groups in poly(diallyldimethylammonium chloride) (PDDA) enable strong electrostatic binding to polybromides, effectively confining them within the cathode and preventing diffusion into the electrolyte. Simultaneously, a lotus-leaf-biomimetic interphase with high electronegativity and hydrophobicity is constructed on Zn anode to repel polybromides and suppress parasitic reactions. Theoretical calculations and in situ spectroscopic analyses confirm the effective suppression of polybromide shuttling and Zn corrosion.

We identify a “surface passivation effect” in photocatalysis, wherein the PPOA modification on CeO 2 overlayers not only suppress the adsorption and activation of oxygen but exhibit strong resistance to hydrogen reduction during POWS. This dual functionality effectively suppresses the reverse reactions by blocking the redox cycle of exposed Rh sites and defective CeO 2 overlayers, resulting in significantly enhanced photocatalytic activity and stability.

Three hydroxyl-substituted phenylacetic acids (p-hydroxyphenylacetic acid, 3,4-dihydroxyphenylacetic acid, and 2-(3,4,5-trihydroxyphenyl)acetic acid) are incorporated into the perovskite films to investigate the significance of their interaction modes with perovskite in regulating f-PSC performance.

In this study, a tandem-triggered transition system is presented that enables the transformation of single-phase coacervates into multiphase structures through the sequential application of two external stimuli: pH and salt concentration. A polyanion containing acid-labile amide bond is incorporated into the membrane-less coacervates. Upon exposure to an acidic pH, hydrolysis of the amide bond induces charge reversal from polyanion to polycation, triggering the first transition from single-phase to nested multiphase coacervates. This transformation alters the spatial redistribution and viscosity of coacervate components and influences sequestration behavior toward various (macro) molecules. Subsequently, the introduction of hypertonic environment as secondary stimulus induces selective dissociation and structural reconfiguration of nested multiphase coacervates into vesicular-like multiphase coacervates, further altering the coacervate components' fluidity and partitioning properties. Notably, the diverse inherent properties of coacervates among this tandem-triggered transition enables the variation of spatial organization for enzymatic reactions.

  @article{ , abstract = {Aqueous zinc-ion batteries suffer from electrolyte-induced degradation despite their inherent safety advantages. While localized high-concentration electrolytes (LHCEs) mitigate interfacial instability, the excessive cation–anion association elevate ionic transport barriers, resulting in sluggish migration kinetics. Herein, ion-decoupled LHCE (ID-LHCE) are proposed using amphiphilic 2,2,3,3-tetrafluoro-1-propanol (TFP) as anion-affinity diluent. The TFP-mediated anion-diluent matrix (ADM) liberates anion OTF − from Zn 2+ solvation sheaths, which maintains Zn 2+ -enriched nanodomains while significantly reducing ionic transport barriers with an elevated Zn 2+ transference number of 0.72. ADM decouples aqueous networks into biphasic H 2 O-rich/poor nanodomains, establishing a localized environment with attenuated water activity that suppresses hydrogen evolution reaction. Concurrently generated water-deficient interfaces and dehydrated OTF − coordination environment synergistically facilitate the construction of dense gradient heterogeneous SEI: an inner ZnF 2 -ZnS inorganic layer and an outer oligomer layer, enabling dendrite-free zinc deposition with ultralong cyclability (3,000 h at 1 mA cm −2 ) and 99.88% coulombic efficiency. Full cells paired with NaV 3 O 8 ·1.5H 2 O cathodes retain 72.5% capacity retention after 2,000 cycles at 0.5 A g −1 . Practical viability is demonstrated by the stable operation of high mass loading ampere-hour-level pouch cells (1.04 Ah).

Herein, we present a versatile strategy for developing cell-active covalent kinase inhibitors (CKIs) by selectively targeting unique surface-exposed lysines using squarate chemistry.

Amongst various AURKA CKIs, AL8 emerged as the first-in-class squarate-based, cell-active inhibitor, exhibiting excellent selectivity in both biochemical and cellular assays with long-residence time in covalently engaging endogenous AURKA.

  @article{ , abstract = {The study of polycyclic aromatic hydrocarbons has become a cornerstone of chemical sciences, providing crucial guidance for advancing a wide range of fields. Within this context, quasi[8]circulenes and indenofluorenes (IFs) have gained considerable attention due to their rich chiroptical, optoelectronic, supramolecular, and redox properties. However, their combined integration into a single molecular framework has not yet been realized. This work demonstrates that curved indeno[2,1- c ]fluorene quasi[8]circulenes are easily accessible through an intramolecular cyclization of a readily available helicene diketone. The cyclization is high yielding and accompanied by an unexpected regioselective triflation that—alongside both ketones—allows orthogonal functionalization. This synthetic utility offers great potential for incorporating 8-membered rings and formally antiaromatic as -indacene moieties into complex architectures. Herein, a series of fully conjugated antiaromatic indeno[2,1- c ]fluorene quasi[8]circulenes were synthesized and studied spectroscopically and electrochemically, showcasing the rich properties of these rare, purely carbon-based quasi[8]circulenes. It is shown that the studied compounds display multiple accessible redox states at mild potentials, which can be significantly altered through adequate substituents. These substituents additionally induce unprecedented aggregation behavior for one of the compounds.

Here, we designed and engineered a biosensor fusing the green fluorescent protein EGFP and the nitrate recognition domain NreA from Staphylococcus carnosus . Seven rounds of directed evolution and 15 mutations resulted in NitrOFF. NitrOFF has a high degree of allosteric communication between the domains reflected in a turn-off intensiometric response ( K d ≈ 9 µM). This was further reinforced by X-ray crystal structures of apo and nitrate-bound NitrOFF, which revealed a large-scale conformational rearrangement changing the relative positioning of the domains by 68.4°. This dramatic difference was triggered by the formation of a long helix at the engineered linker connecting the two domains, peeling the β7 strand off the EGFP and thus extinguishing the fluorescence upon nitrate binding.

Upon treatment of the Fe/Se homologues with O 2 – as in case of the parent cysteamine-bound complexes – the dioxygenation of the chalcogen atoms was observed. This suggests that the lack in reactivity of CDO-Sec toward O 2 does not originate in the electronic situation but in the surrounding protein matrix. Subsequent DFT calculations indeed showed lower initial barriers for selenocysteamine than for cysteamine in support of the experimental work.

  @article{ , abstract = {Electronic structures fundamentally influence material properties, with electron spin playing a pivotal role in defining catalytic activity and reaction pathways. However, the precise spin-mediated mechanisms of adsorption energies and nitrogen–nitrogen transition states on the catalyst surface, remain unclear due to the complexity of spin-mediated promotion factors. Herein, we demonstrate that tuning the spin state of single iron (Fe) sites on TiO 2 can significantly enhance photocatalytic nitrogen reduction reaction (NRR). Our theoretical predictions reveal that low spin states of single Fe sites facilitate N 2 adsorption and intermediate formation, thereby activating more catalytic sites on TiO 2 for efficient nitrogen fixation. By manipulating the crystal phase and incorporating fluorine dopants, we systematically modulate the spin states of Fe sites, achieving optimized N 2 adsorption and desorption kinetics and suppressing charge recombination. Experimental results combined with density functional theory (DFT) calculations confirm that these modifications reduce the magnetic moment of Fe sites, lower free energy barriers, and strengthen electronic interactions with key intermediates, particularly during N─NH formation. Intriguingly, we find that weakening N 2 adsorption via reduced Fe magnetization enhances catalytic performance, challenging conventional assumptions that stronger N─N bond activation necessarily improves NRR efficiency. Our experimental results corroborate these findings, showing a remarkable 72-fold increase in ammonia production rate compared to pristine TiO 2 . This work highlights the crucial role of electron spin engineering in designing highly efficient NRR catalysts and provides a new paradigm for rational catalyst design.}, archive = {J_ANGEW}, author = {Xiao Ge and Xiyang Zheng and Tao Zhou and Li-Jiao Tian and Wei Wang and Jie-jie Chen and Xiaozhi Wang}, doi = {10.1002/anie.202506470}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {40}, pages = {e202506470}, shortjournal = {Angew.

  @article{ , abstract = {Photoenzymatic catalysis facilitates stereoselective new-to-nature chemistry under mild conditions. In addition to the rational design of artificial photoenzymes, naturally occurring redox enzymes can be repurposed to promote photoredox catalysis in the chiral protein environment. Here, we show that enzymes utilizing the pyrroloquinoline quinone (PQQ) cofactor expand the toolbox of photobiocatalysis. PQQ absorbs visible light and is capable of single-electron transfer. It thus exhibits mechanistic similarities to flavin cofactors, which are widely used for photoenzymatic approaches. First, we established the trimethyl ester PQQMe 3 as a stand-alone photoredox catalyst in pure organic solvent. Upon excitation, PQQMe 3 enables the redox-neutral radical cyclization of an N -(bromoalkyl)-substituted indole. We then tested a panel of PQQ-dependent sugar and alcohol dehydrogenases for photoenzymatic catalysis in aqueous buffer, focusing on a redox-neutral radical reaction to form oxindoles. Under optimized reaction conditions, we obtained a 69% yield and an 82:18 enantiomeric ratio. Our work thus demonstrates that PQQ enzymes are capable of stereoselective photoredox catalysis.

However, one major challenge for developing SICPEs with higher ambient ionic conductivity comes at the expense of structural robustness. Here, boron ion-centered lithium salt (LiT4PAB) with symmetric cross structure and terminal functional C═C was proposed as a units, and then 3D coordination electrolyte (LiPHB) was constructed via chemical cross-linking of LiT4PAB with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP). The boron ion-centered units catenated by single bonds show the abundant conformation transitions, enabling the deformable architecture of LiPHB with the aid of electrostatic interactions of diphenylsulfonimide.

While several metal complexes have shown promise as ICD inducers, conjugates containing more than one metal center remain to be explored for ICD. Here, we report the design, synthesis, and evaluation of a tri-metallic Au I -Pt IV -Ru II prodrug ( 5 ) that codelivers oxaliplatin (Type I ICD inducer), Ru II arene 2-pyridinecarbothioamides (Type I), and Au(I) bis-N-heterocyclic (Type II) using a single scaffold. Upon reduction, complex 5 releases all three cytotoxic species, resulting in enhanced inhibition of thioredoxin reductase (TrxR1&2), elevated production of reactive oxygen species (ROS), and in vitro DAMP release. In vivo studies of complex 5 in a colorectal cancer mouse model demonstrated tumor growth suppression, reduced off-target metal accumulation, and improved immune memory in a tumor challenge study compared to a 1:1:1 mixture of the constituent agents. Furthermore, peripheral white blood cell (WBC) profiling revealed that complex 5 activates both the innate and adaptive immune compartments. This study demonstrates an integrated chemo-immunotherapeutic strategy that unifies multiple ICD triggers within a single prodrug framework. It thus highlights a promising approach to the creation of metal-based multimodal anticancer therapies.}, archive = {J_ANGEW}, author = {Tomer Babu and Matthew S.

While this property has been extensively exploited for probing of homomultivalent interactions, there has been comparatively little attention paid to the exploration of heteromultivalent interactions. In this study, we investigated the use of readily assemblable DNA duplexes for programming bispecific targeting of specific cell types. In contrast to previous bispecific agents, we leverage the potential of peptide-based high-affinity binders of cell surface proteins used in diagnostics/therapeutics. Systematic spatial screening revealed the optimal distance between two (cyclo)peptides required for selectively recognizing cells expressing unique combinations of receptors. The VGFR2/α V β 3 receptor system on HUVECs was tolerant to changes of the distance between two cyclopeptides (L and cyclo(-RGDf( N -Me)K-)) and required that the distance exceeded the equivalent of 20 nucleotides distance. A different distance-affinity landscape was observed for recognition of EGFR and MET on A549 cells (through GE11 and bicyclic peptide GE-137). The DNA-programmed bispecific binders demonstrated specificity and efficient internalization into target cells. Auristatin-loaded DNA enabled a selective targeting of cytotoxic payload.

Typically, replacing 90% PS [Ir(bpy)(coumarin6) 2 ] + ( Ir-2 ) with an earth-abundant Co 7 POM ([{(B-α-PW 9 O 34 )Co 3 (OH)(H 2 O) 2 (O 3 PC(O)(C 3 H 6 NH 3 )PO 3 )} 2 Co] 14− ) can efficiently boost photo-oxidation efficiency, achieving complete substrate conversion within 3 h in air, ∼3.2 or 5.6 times higher than the system with 100% or 10% Ir-2 , respectively.

Its short- to medium-range ordered structure was resolved using the advanced total scattering atomic pair distribution function (PDF). The unique architecture of POF-2 synergistically combines the strong oxidative capability of AsPOM with the tunable light absorption and oxygen activation ability of organic monomers, narrowing the bandgap from 3.13 eV (AsPOM) to 2.28 eV (POF-2) and extending light absorption to 575 nm.

To address this, we introduce a rapid in situ interface reaction at the buried interface between the perovskite layer and the underlying poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) film. This engineered interface reaction represents a novel method for preparing high-quality deep-blue CsPb(Br/Cl) 3 films.

To overcome these limitations, a spatially engineered Nb 2 C/Nb 2 O 5 /ZnO ternary heterostructure is developed by anchoring ZnO quantum dots (QDs) onto Nb 2 O 5 nanorods grown in situ from Nb 2 C MXene. This architecture integrates an Nb 2 O 5 /ZnO S-scheme heterojunction and an Nb 2 C/Nb 2 O 5 Schottky junction, sharing Nb 2 O 5 as a central mediator, thereby establishing bidirectional interfacial electric fields (IEFs) that direct photogenerated electrons toward ZnO and holes toward Nb 2 C.

Using flat carbon layers as a model, we show that charge effects significantly influence the identification of active Na-storage sites and induce sodiation/desodiation voltage shifts exceeding 1.1 V relative to conventional charge-neutral models. These effects originate from distinct chemical reactivities between neutral and charged carbon. When extended to curved and defect-rich carbon—hallmarks of HC—CDM accurately predicts storage sites and voltage-capacity profiles that closely match experimental data.

This unique tool requires the introduction of just a single point mutation that modulates the glycation susceptibility of a nearby arginine. As proof-of-concept, extensive mass spectrometry analysis was performed to confirm that dialAGE can modulate site-specific glycation levels at multiple arginine residues in ubiquitin in vitro, enabling both enhanced and diminished glycation.

A further increase in potential activates the direct oxidation process of Cu III ─OOH, selectively oxidizing hydroxyl groups owing to the increased substrate coverage on the catalyst, which hinders aldehyde adsorption.

  @article{ , abstract = {The incomplete conversion of sulfur species, particularly the pivotal intermediate solid Li 2 S 2 during redox processes, poses a significant limitation on the cyclability of lithium–sulfur batteries (LSBs). Herein, a synergistic modulation strategy of ion-/dipole–dipole interactions that tailors the solvation sheath configuration and activates the electrochemical reactivity of Li 2 S 2 is initially proposed for accelerating kinetics. As a proof of concept, the molybdenum nitride quantum dots located on nitrogen-doped carbon (MoNQDs/NC) were designed. Advanced in situ/ex situ characterizations combined with theoretical calculations reveal that MoNQDs/NC effectively weaken the ion-dipole interactions within Li(solvent) x + species, thereby facilitating the desolvation process. Furthermore, the robust dipole–dipole interactions between polar domains of MoNQDs and Li 2 S 2 are realized to generate localized tensile strain fields to destabilize the S─S/Li─S bonds network. Consequently, the optimal cells maintain a high areal capacity (>5.0 mAh cm −2 ) after 50 cycles at high sulfur loading (4.4–9.1 mg cm −2 ) over a wide temperature range (0–60 °C).

Concurrently, a nitrate-enriched solution is generated through plasma-mediated activation of air and water under ambient conditions. Subsequently, the PA and nitrate solutions are mixed and directly introduced to the electrochemical reactor. We employ a strain-engineered CuBi alloy electrocatalyst capable of stably catalyzing alanine production via co-electrolysis of PA and nitrate. This integrated process establishes a sustainable pathway to valorize low-cost feedstocks into high-value commodity chemicals using renewable energy while mitigating plastic pollution.}, archive = {J_ANGEW}, author = {Yingxin Ma and Xuyun Guo and Mengxiang Han and Jizhe Ma and Mingzhu Han and Lejuan Cai and Valeria Nicolosi and Wenlong Wang and Weiliang Dong and Min Jiang and Bocheng Qiu}, doi = {10.1002/anie.202511466}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {39}, pages = {e202511466}, shortjournal = {Angew.

We identified 48 promising candidate molecules by this high-throughput screening method, among which cyanoacetamide (CA) and hydantoin (HN) were experimentally validated as novel electrolyte additives for AZIBs that have not been reported previously. The experimental and calculation results demonstrate that CA and HN preferentially adsorb onto the surface of the zinc anode, resulting in the enhanced interfacial stability of zinc anodes.

High luminescence brightness, outstanding photostability, near-infrared excitation and emission, spectral and temporal multiplexing, and large surfaces for multifunctional bioconjugation are only some of the features that make luminescent NPs very attractive for biosensing, and FRET efficiencies up to 90% have demonstrated their potential for successful translation into bioanalytical applications.}, archive = {J_ANGEW}, author = {Eduard Madirov and Clara Catros and Niko Hildebrandt and Chloé Grazon}, doi = {10.1002/anie.202510801}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {39}, pages = {e202510801}, shortjournal = {Angew.

  @article{ , abstract = {Chirality-driven self-assembly is crucial in biological systems, but achieving precise control over chiral narcissistic or social self-sorting as well as the distinction between them remains a major challenge in multicomponent supramolecular systems. To investigate chirality-driven self-assembly, two classes of chiral building blocks, photo-responsive (cinnamic glutamide derivative, L/D-CG) and fluorescent molecules (dansyl glutamide derivative, L/D-DNSG), were designed and integrated into homochiral systems (L-CG/L-DNSG or D-CG/D-DNSG) and heterochiral systems (L-CG/D-DNSG or D-CG/L-DNSG). Either homo- or heterochiral systems could form organogels with fibrous structures. Upon photoirradiation, the homochiral systems remained stable, whereas the heterochiral systems underwent a significant transformation from uniform organogels to suspensions, in which nanokebab structures appeared. The results demonstrate that social self-sorting dominates in the homochiral systems while narcissistic self-sorting prevails in the heterochiral systems. Remarkably, the difference between homochiral and heterochiral systems is magnified through photodimerization. Various characterizations and simulations unveil the underlying homo- and heterochiral interactions that drive narcissistic self-sorting from the molecular to hierarchical nanoscale levels.

While persistent triplets are often selected to drive chemical bond formation or spin-specific photoreactions, singlets can allow for ambient applications. Among different heterogeneous systems, metal–organic frameworks (MOFs) offer a solution-stable platform with many benefits, including large chemically accessible interior surfaces where excitons can be transferred from their original formation sites. Porphyrins demonstrate high intersystem crossing efficiency, with QY ISC ≈ 80% for free-base (FB) cores, which can be increased to about 92% for palladium-metalated cores. This study shows that framework assembly prevents ISC in FB-MOFs; whereas, ISC is enhanced in Pd-MOFs compared to monomeric linkers. The MOF topology influences the excited state dynamics, resulting in short-lived triplets with τ 0.5 ≲10 ps in microporous MOFs.

To address this, we developed a novel aniline-type diarylethene (DAE) crosslinker and prepared a series of corresponding poly( N -vinylcaprolactam)-based microgels with varying degrees of DAE crosslinker. Upon UV light irradiation, the aniline (and thus enamine) motif of the DAE is converted to its imine form, thus allowing for reversible exchange with primary amines. Irradiating the DAE with blue light covalently locks the equilibrium and traps the amine in the microgels. The light-controlled covalent binding of fluorinated, hydrophobic, and hydrophilic amine derivatives was proven by dynamic light scattering and 19 F NMR spectroscopy. Importantly, the impact of photoisomerization and amine binding on microgel properties was investigated and we were able to remotely control size as well as temperature and pH responsiveness by light.

Nonetheless, Pt's unique d-band structure permits a high density of electronic states near Fermi energy. It should have exhibited photoenhanced catalysis. Here, guided by finite-different-time-domain (FDTD) calculations, we take advantage of Pt electronic structure by designing a sub-100 nm colloidosome (Cs) consisted of ultrasmall (≤ 5 nm) Pt NPs with broadband absorption from visible to near-infrared (NIR) band. The ultrasmall Pt NPs in the Cs efficiently generated hot electrons even under excitation with the low-energy electromagnetic radiation. The key for realization of Cs is the exploitation of laser-generated, grain boundaries (GBs) enriched Mn 3 O 4 NPs as scaffolds for the efficient and homogeneous loading of ultrasmall Pt NPs. These Pt Cs show outstanding performances as catalase (CAT) and oxidase (OXD) mimics under NIR band irradiation, allowing their use for photocatalysis of oxidation reactions.

Innovatively, an n-type 2D perovskite functional layer featuring a distinctive edge/corner-sharing (E/C-sharing) [PbI 6 ] 4− octahedral framework is constructed on a 3D film surface by utilizing N -methylethylenediamine cations (MEDA 2+ ) to regulate the connection modes of [PbI 6 ] 4− octahedral units. Specifically, the 2D-MEDAPb 2 I 6 with the E/C-sharing octahedra yields the narrowest interlayer spacing recorded to date (8.39 Å) among 2D perovskites, thus boosting the octahedral interlayer coupling effect and weakening the quantum and dielectric confinement effect to improve carrier mobility. Additionally, the 2D capping layer reinforces surface lattice stability by inducing a compressive stress field and increasing defect formation energy. The resulting type-II 3D/2D heterojunction significantly lowers the interfacial energy barriers for electron transfer and reduces the carrier recombination losses. Consequently, the inverted PSCs achieve an optimal efficiency of 26.43% (certified at 26.10%) and maintain over 94% of their initial efficiency after operating for 1200 hours under simulated AM 1.5G illumination.

However, achieving both high cascade selectivity and polymerization efficiency remains a significant challenge. Herein, we report our efforts to enhance cascade efficiency (CE) in CMP of various dicycloalkenes and explore their closed-loop chemical recycling. A comprehensive investigation revealed that second-generation Grubbs catalysts ( G2 and DIPP-G2 ) exhibited superior cascade selectivity (CE up to >99%) and polymerization efficiency (turnover numbers up to 3550) compared to first-generation Grubbs catalyst ( G1 ). This is attributed to a preferred intramolecular cascade pathway that suppresses competing ring-opening metathesis polymerization (ROMP). Polymers with high CE showed markedly improved glass transition temperatures ( T g ), by up to 47 °C. Remarkably, in-depth studies on sulfonamide-based dicycloalkenes uncovered an unexpected intramolecular cascade transformation, forming new bicyclic monomers, which underwent ROMP and yielded highmolecular-weight polymers ( M n up to 141 kDa). Importantly, these well-defined polymers underwent selective and complete depolymerization into small molecules via reverse CMP or ROMP, which then were repolymerized thereby achieving closed-loop recycling. Computational studies explained how these small molecules were preferentially formed.

Time-dependent DFT computations further have revealed small T1–S1 energy gaps, suggesting potential applications of similar scaffolds in thermally activated delayed fluorescence (TADF) materials. Our analyses have identified the cation on C7 as the most reactive site on the molecule toward unwanted reactions, leading to the degradation of the ylides.

  @article{ , abstract = {Freshwater scarcity and nitrate contamination in water sources are critical environmental sustainability challenges. We address these two challenges by coupling seawater desalination with electrochemical nitrate reduction (NO 3 RR) via bimetallic Fe/Zn polyphthalocyanine frameworks.

The efficient NO 3 RR is integrated into an electrocatalytic desalination device, enabling the production of freshwater from seawater and the removal of nitrate from contaminated water. In situ spectroscopic studies and theoretical calculations show that Zn-N 4 units incorporated into the Fe polyphthalocyanine framework modulate Fe-N 4 sites’ d-band center to enhance the adsorption of NO 3 − and the generation of *H, resulting in 3.22 times higher turnover frequency and highly selective reduction toward NH 3 . The optimized Fe 8 Zn 1 PPc delivered NH 3 Faradic efficiency (>97% over a wide potential range (−0.55 to −0.95 V vs. reversible hydrogen electrode (RHE)), the NH 3 yield rate of 2.68 mmol h −1 cm −2 at −0.85 V versus RHE, and over 120 h of stable operation, outperforming previously reported Fe-based catalysts for NO 3 RR.

  @article{ , abstract = {Mixed-linker-based multivariate metal-organic frameworks (MTV-MOFs) recently received considerable research effort because they exhibit tailored physicochemical properties that are often not possessed by single-linker MOFs and therefore find unique applications. Relative to the pristine linker, the incorporated linkers may tend to form different topologies, bringing about lattice mismatch and structural disorder. This leads to a low mixed-linker incorporation limit, and further increasing the linker incorporation rate may disrupt the crystallinity of the parent MOF, resulting in amorphous products or other topologies. Therefore, increasing the linker incorporation rate without changing the structure of the parent MOF represents a challenge. Herein, for the first time, an MTV-MOF of imidazole-incorporated zeolitic imidazolate framework ZIF-7 is constructed by 60 Co gamma ray radiation. Both experiments and theoretic calculations demonstrate that the distinct radiation-induced activation of the synthesis reaction gives rise to a much higher mixed-linker incorporation limit in ZIF-7, up to twice that synthesized by the solvothermal process, further leading to increased flexibility of aperture, higher specific surface area, and notably enhanced separation performances for Kr and Xe.

The aptamer probe is extended with a double-stranded DNA carrier to enhance protein transport and detection efficiency. Upon protein binding, dimerization of the DNA carriers occurs, allowing charge-based classification of bound versus unbound states. Additionally, the sandwich complex produces a characteristic subpeak within individual nanopore events, with subpeak height correlating to protein size. This approach enables selective detection of dimeric proteins, including vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF), with sub-picomolar detection limits.

  @article{ , abstract = {Inverse-electron demand cycloaddition reactions of tetrazines are widely used in bioorthogonal chemistry, but the opposing effects of substituents on reactivity and stability make optimizing tetrazines for chemical biology applications challenging.

We synthesized a series of tetrazines designed to explore these kinetic properties. A novel computational method quantifying intermolecular atomic contributions to dispersion forces supported the analysis substituent effects on tetrazine reactivity.

Three organic donor–acceptor (D–A) molecules with different molecular configurations are designed and synthesized, which can readily form modulated packing patterns with fastidiously regulating intermolecular charge transfer (CT) in crystalline states. Experimental and theoretical investigations expose that the intermolecular D–A packing modes could be formed in relatively planar molecular architecture, which cannot only fix the intermolecular CT excited-state configuration, but the multiple conversion channels of triplet excitons can also be involved synergistically to accelerate the spin-flip, and thus achieving near-unity PLQY and excellent reverse intersystem crossing rate of 6.7 × 10 5 s −1 in solid states.

A 24-crown-8 ring is sufficiently small that the side chains of canonical branched amino acids act as barriers that trap the macrocycle on the particular glycine residue used to assemble the rotaxane. The resulting crown ether–tripeptide rotaxane can subsequently be extended from either or both N- and C-termini of the axle. Three distinct positional isomers of a heptapeptide [2]rotaxane containing three glycine units were selectively synthesized, and in each case the unique position of the crown ether on the peptide axle was confirmed by 1 H nuclear magnetic resonance spectroscopy and tandem mass spectrometry. The three positional isomers adopt different conformations in the region adjacent to the trapped macrocycle, and have different chemical stabilities and secondary interactions in comparison to the unthreaded peptide axle. The crown ether does not inhibit enzymatic proteolysis over the entire length of the heptapeptide–axle rotaxanes, but rather provides significant protection from degradation for the three to four residues local to the encapsulated region.

The first SP (Type I) is characterized by a uniform diameter and circularity, whereas the other (Type II) has properties reminiscent of flexible cyclic covalent polymers. Remarkably, the only difference in the structures of the two monomers that form these completely distinct cyclic SPs is the absence (Type I) or presence (Type II) of hydrogen-bonding moieties. An all-atom molecular-dynamics simulation suggested that the Type II SP can adopt various “conformations” due to the dynamic nature of its hydrogen bonds, thereby behaving like a flexible covalent polymer. Real-time high-speed atomic-force microscopy (AFM) confirmed the presence of flexibility in the chains of the Type II SP on the observation timescale (several tens of seconds).

Through AlphaFold modeling, in vitro biochemical characterization, and spectroscopic analysis, we demonstrate that CctR is a membrane-associated copper-dependent enzyme that functions as a homodimer.

  @article{ , abstract = {While considerable research efforts have been devoted to developing narrowband B,N-embedded multiple resonance (BN-MR) emitters, despite the formidable challenge, the design of efficient narrowband red phosphors has been overlooked. Herein, we present a design strategy that perpendicularly integrates BN-MR frameworks into a weakly emissive tetradentate Pt(II) complex to achieve efficient narrowband phosphors. Accordingly, we synthesized two novel emitters, BCzBN-PyPt and DPABN-PyPt. The optimized emitter BCzBN-PyPt exhibits exceptional performance characteristics: 1) narrowband red emission at 605 nm with a small full-width at half-maximum (FWHM) of 35 nm/0.118 eV in toluene, 2) a dramatically shortened exciton lifetime of 1.2 µs (compared to 7.6 µs for the parent complex PhPyPt), and 3) a remarkable photoluminescence quantum yield ( Φ PL ) of 75% in doped films–representing a 4.4-fold enhancement over PhPyPt ( Φ PL = 17%). Theoretical investigations reveal that the BN-MR skeleton induces significant electronic perturbation of the singlet state, leading to enhanced transition dipole moments and accelerated radiative decay ( k r = 3.3 × 10 5 s −1 versus 0.1 × 10 5 s −1 for PhPyPt).

Herein, for the first time, we synthesized three novel COFs with different dimensions, from similar composition by manipulating the conformation of the molecular building blocks through repulsion-torsion effect. Impressively, the strong repulsion-torsion effect transformed the planar building block into a non-planar building block, resulting in the construction of 2D and 3D COFs, respectively. Moreover, when we consciously reduced the repulsion-torsion effect, the resulting intramolecular conformation struggled to meet the requirements for the formation of 2D and 3D structures, ultimately generating a rare 1D COF. Further research indicated the charge transfer efficiency and photocatalytic performance of the resulting COFs followed a dimensional order of 1D > 3D > 2D.

In contrast, in the liquid state, the donor transitions to a relatively planar conformation, forming the intermolecular charge transfer state with the acceptor, significantly reducing the energy gap between the lowest singlet and triplet excited states, thereby facilitating reverse intersystem crossing (RISC) and generating yellow DF.

This top-down reconstruction strategy involves the disintegration of 1,4-ndc linker and transformation of 1D Ni–( μ 3 -OH)/( μ 2 -H 2 O)–Ni chains (which act as precursors), into ultra-low-dimensional (thickness ∼ 1.5–2.6 nm), defect-rich β -Ni(OH) 2 structure. The activated catalyst achieves a low overpotential of 300 mV at 10 mA.cm −2 , surpassing commercial IrO 2 . In situ Raman and powder diffraction studies demonstrate pH- and potential-dependent phase transitions, leading to the formation of catalytically active β -Ni(OH) 2 . In situ X-ray absorption spectroscopy (XAS) confirms progressive structural evolution, with a Ni─O bond contraction from 2.06 to 1.89 Å under catalytic conditions, indicative of dynamic NiOOH phase formation.

  @article{ , abstract = {Next-generation lithium-ion batteries (LIBs) require electrolytes compatible with high-voltage (>4.3 V) and low-temperature (<−10 °C) operation, yet commercial ethylene carbonate (EC)-based systems remain constrained by intrinsic limitations including poor oxidation stability at cathode side and high melting points. Although propylene carbonate (PC) demonstrates superior oxidative stability and lower melting temperature than EC, its tendency to cointercalate with Li + within the graphite anode interlayers restricts its applicability in LIBs. We propose a PC-based weakly-solvating electrolyte engineered with difluoroethylene carbonate (DFEC) that resolves interfacial challenges at both electrodes. The PC solvent facilitates oxidative resistance through formation of an inorganic-dominated cathode–electrolyte interphase (CEI), effectively mitigating transition metal dissolution at 4.4 V operation. Simultaneously, DFEC disrupts Li + -PC coordination through reduced solvent molecule numbers in the solvation shell, enabling generation of a stable solid electrolyte interphase (SEI) on graphite anodes with minimized interfacial impedance. Implemented in 5 Ah pouch cells, this electrolyte demonstrates 76.7% capacity retention after 2000 cycles (2.8–4.4 V) at room temperature (RT) and maintains 91% of its RT capacity at −20 °C, surpassing conventional EC-based electrolytes.

The stability and radical nature of CNPJ were first corroborated by nucleus-independent chemical shift (NICS) calculations. Structural analyses revealed two critical phenomena enabled by efficient spin delocalization and intermolecular charge transfer: i) polarity-triggered radical center redistribution and ii) thermally regulated monomer‒π dimer equilibrium.

  @article{ , abstract = {Achieving modular, selective and homogeneous protein modifications is of utmost importance for the design of next generation biopharmaceuticals, especially in the context of antibody-drug conjugates (ADCs). Here, we introduce unsaturated phosphine oxides as versatile triple-reactive reagents, allowing orthogonal chemoselective bioconjugation schemes. Starting from triethynyl-phosphine oxide, a variety of functionalized diethynyl-triazolyl-phosphine oxides (DTPOs) could be accessed by using Cu I -catalyzed azide-alkyne cycloaddition (CuAAC). We showcase DTPO-reagents in the fast and selective generation of various highly stable antibody-conjugates via antibody disulfide rebridging. A highlight from this methodology is the synthesis of a DAR 4 ADC following a modular 2-step strategy using bioorthogonal tetrazine-labeling with bicyclo-[6.1.0]non-4-yne (BCN) or trans -cyclooctene (TCO) containing payloads. Notably, the DTPO-rebridged ADC exhibited potent cytotoxicity against Her2 + cancer cells. Moreover, we utilize triethynyl-phosphine oxide to obtain ethynyl-ditriazolyl-phosphine oxides (EDPOs) which enable a unique, single-reagent peptide-cyclization-bioconjugation protocol resulting in functional cyclic peptide-protein conjugates.

To establish high versatility in the current repertoire, we have designed and synthesized six psUAAs based on azobenzene, arylazopyrazole, arylazothiazole, hemithioindigo and spiropyran photoswitches.

Tunable self-trapped excitons (STEs) emission from 606 to 678 nm originated from [SbCl n ] 3-n are realized in these 0D structures by Sb 3+ doping at room temperature. The correlations among structural distortion, bandgap, emission position, and quantum yield are investigated in these 0D Sb 3+ -doped OIMHs. The greater distortion of local inorganic polyhedron induces a relative red-shift emission, while the increased separation distance between local inorganic polyhedron reduces non-radiative transitions, therefore enhancing quantum yield. Moreover, multi-emission centers are constructed in Sb 3+ /Bi 3+ -doped PMA 4 InCl 7 , achieving green/red and blue/green/red tunable multi-color switching luminescence under the regulation of excitation wavelength and temperature.

Using enantiopure aminoacyl phosphate esters, we show that these left- and right-handed acylating agents generate transient epimeric (thio)-esters from homochiral peptide substrates, leading to supramolecular architectures with distinct lifetimes and self-assembly dynamics. Moreover, chirality regulates downstream reactivity in cascade reactions, where stereochemical control over an intermediate propagates into subsequent transformations. Finally, chiral acylating agents differentiate between two reaction cycles, selectively modulating one pathway while keeping another invariant – a level of control that remains difficult to achieve with conventional chemical strategies. Stereochemical programming enables control over reactivity and self-assembly, offering new opportunities to encode chirality in reaction networks and modulate their function through a single molecular parameter.}, archive = {J_ANGEW}, author = {Lenard Saile and Kun Dai and Mahesh D.

Herein, we unveiled the direct oxidation mechanism of three electrode models, Co 4 N, CoO, and Co 4 N–CoO, in which the adsorptions of OH − and glycerol on the electrodes were competitive. The adsorption of glycerol on Co 4 N was quite strong but weak on CoO, whereas the CoO preferred to adsorb OH − species. The one-sided adsorption properties of surface reactants led to the sluggish electrooxidation kinetics of organics on Co 4 N and CoO. Constructing Co 4 N–CoO heterointerfaces significantly balanced the one-sided adsorption features. Due to the moderate OH − and glycerol adsorptions on Co 4 N–CoO, the OH − was mainly used to activate glycerol rather than trigger the oxidative reconstruction of materials to form high-valence OER sites. Consequently, the Co 4 N–CoO showed excellent glycerol oxidation properties. The Co 4 N–CoO delivered a lower Tafel slope of 178 mV dec −1 while achieving a high formate yield rate of 29.40 mmol cm −2 h −1 .

  @article{ , abstract = {Amorphous silica–alumina are critical materials in catalysis, particularly for fluid catalytic cracking (FCC). However, the atomic scale understanding of the active sites has been challenging, because of the nonuniform atomic distribution and the material's amorphous nature. Here, we use density functional theory (DFT), machine learning potentials and sampling methods to investigate the relationship between structure and acidity in silica-modified alumina. Under FCC conditions, we predict an ensemble of acid sites with diverse local structures and a spectrum of acid strengths, including zeolite-like bridging Brønsted acid sites (BAS) and pseudo-bridging silanol BAS. This distribution is influenced by surface structure, Si coverage, and extent of hydroxylation, shaped by synthesis methods and reaction conditions. Experiments using a model Si-stabilized alumina catalyst confirm that Brønsted acidity increases with Si content, peaking at an optimal value before declining.

  @article{ , abstract = {Fluorination of electrolyte solvents is key to improving the cycling stability of high-voltage lithium metal batteries (LMBs), yet the critical role of fluorinated alkyl chain length in governing solvation and interphase chemistries remains unclear. Herein, we systematically engineered a series of methoxy ethoxy methane derivatives with tailored fluorinated alkyl groups to screen the optimal asymmetric difluorinated electrolytes for high-voltage LMBs. Spectroscopic and computational studies show that the ─CF 2 H group in difluoroethoxy methoxy methane (DFME) facilitates balanced Li─F interactions, which are essential for ensuring efficient ion transport and maintaining oxidation stability. In contrast, the elongated ─CF 2 CF 2 H group in tetrafluoropropyl methoxy methane (TFME) fails to coordinate with Li + ions, which hampers ion transport and leads to interfacial instability. The DFME electrolyte facilitates the spontaneous formation of a protective dual-layer interface featuring a LiF-rich inner phase and a Li 2 CO 3 -dominated outer phase. Consequently, Li||LiCoO 2 cells (2.5 mAh cm −2 ) using DFME exhibit remarkable cycling stability, retaining 92% capacity after 180 cycles.

Photocatalytic nitrogen reduction reaction (PNRR) offers a sustainable alternative by harnessing solar energy under ambient conditions.

This study introduces an Fe 3 O 4 @C@ZIF67 core-shell photocatalyst featuring an Fe─N─Co bridged Z-scheme heterojunction. This design incorporates carbon-coated Fe 3 O 4 in ZIF67-D (ZIF67-dodecahedron) with exposed (211) crystalline facets to enhance nitrogen adsorption. Fe─N 4 and Co─N 4 active sites improve catalytic activity, while the carbon layer enhances conductivity and facilitates oxygen vacancy formation.

With CO 2 levels at 427 ppm (50% above pre-industrial levels), deploying energy-efficient carbon capture technologies is crucial. Electrochemical carbon capture processes that have been touted to have the potential to meet these needs rely on the applied cell voltage, and electron utilization (CO 2 molecules separated per electron), which has generally been asserted to have a theoretical limit of one. Here, we introduce an electron-leveraging strategy to enhance electron utilization beyond this limit to 1.43 by employing Fe-EDDHA, a redox-active coordination complex having a ligand with multiple hemi-labile coordination sites. The reversibility and robustness of the system were enabled by the efficient prevention of CO 2 reduction upon the introduction of nicotinamide as a guardian of the iron(2+) center.

Embedding approaches that allow researchers to focus the computational effort on the chemically active regions of interest are promising tools in the pursuit of balancing accuracy and efficiency. However, for metallic catalysts, the required separation of the system into an active part treated with highly accurate methods and an environment is technically hard to achieve due to the delocalization of electrons in the conducting surface. Therefore, studies analyzing the potential of embedding methods for heterogeneous (electro-)catalyst screening are scarce. In this contribution, we demonstrate that simple embedding approaches are indeed achievable for studying metallic catalysts if i) the active orbital space is held consistent over a reaction coordinate and ii) the nonadditive exchange-correlation functional used to calculate the embedding potential includes a fraction of exact exchange to mitigate delocalization errors.

  @article{ , abstract = {Tin-based perovskite films typically exhibit random crystal orientations, with significant accumulation of defects acting as charge recombination centers, which severely limit device performance. Furthermore, the disordered two-dimensional (2D) perovskite significantly impacts the subsequent crystal growth of three-dimensional (3D) perovskite through epitaxial growth mechanism, while the insulating properties of bulky spacer cations impede out-of-plane charge transport. Herein, we have innovatively developed a facile quasi-epitaxial growth strategy by introducing 2-(naphthalen-2-yl)ethanamine hydroiodide (NEAI) with reinforced π-conjugation interaction to construct orientationally aligned 2D perovskite, which acts as a template for 3D perovskite with (100)-dominant facet orientation. NEAI reacts with SnI 2 to pre-form NEA 2 SnI 4 , which subsequently converts to NEA 2 FASn 2 I 7 and ultimately FASnI 3 through an energetically unfavorable pathway to delay crystallization kinetics. Moreover, this innovative approach optimizes carrier transport dynamics while conferring device robust thermal degradation resistance and enhanced long-term stability. Consequently, the NEAI-based solar cells exhibit the impressive efficiencies of 14.03% (0.04 cm 2 ) and 12.44% (1 cm 2 ), representing the record performance for two-step deposited tin-based perovskite photovoltaics.

This study proposes a molecular level design strategy for side-chain azobenzene-containing semicrystalline polymers that demonstrate exceptional intrinsic thermal conductivity with photoresponsive actuation and recyclability. By precisely regulating the spatial distribution and content of azobenzene groups and hydrogen-bond network along the polymer chain through controlled radical polymerization, a thermal conduction network featuring “high-efficiency conduction within crystal domains and low-resistance interfacial connections” was constructed. Azobenzene moieties self-assemble into highly oriented crystalline domains through π–π stacking, where their dense packing significantly enhances phonon coupling efficiency and increases phonon mean free paths. Concurrently, the dynamic reversibility of hydrogen bonds guides domain-boundary molecular chains to form gradual phase transitions, suppressing phonon scattering at amorphous-crystalline interfaces and improving phonon transport efficiency. The film of random copolymer with 35 azobenzene units achieves an outstanding highest intrinsic λ of 2.01 W/(m·K), representing a substantial improvement over its block copolymer counterpart (with a higher crystallinity) and traditional polymers.

Fibrous micelles of about 460 nm are found in the pristine SAMs solution, leading to nonuniform and low coverage distribution of films. Strong dipole molecules are employed to establish supramolecular interactions with SAMs, enabling the formation of highly monodisperse cubic micelles in solution (160 nm) and uniform SAM films.

Control of the energy level of the singly-occupied molecular orbital (SOMO) is essential for the design and application of open-shell materials, but most triarylmethyl radicals are very electron-poor and exhibit similar SOMO values. In this work, we show how a combination of chlorine and methoxy substituents in triarylmethyl radicals allows tuning of their SOMO level over a wide range of –5.7 to –3.9 eV. We demonstrate that both methoxy and chlorine groups provide sufficient stabilization of the radical against peroxide formation, but one-electron oxidation in air limits the SOMO ≤ -4.5 eV to maintain bench stability. Two new stable radicals are characterized by X-ray crystallography, cyclic voltammetry, and luminescence measurements in solution and doped films. We show that the combination of chlorine and methoxy substituents improves the photostability of triarylmethyl radicals compared to tris(trichlorophenyl)methyl (TTM). The extraordinarily large range of SOMO levels in these radicals provides an opportunity to benchmark computational methods for predicting redox potentials.

  @article{ , abstract = {Rechargeable aqueous zinc-ion batteries (ZIBs) are promising energy storage devices due to their high safety and environmental friendliness. However, they suffer from some issues in Zn anodes, including dendrites, hydrogen evolution reaction, and byproducts. Herein, an organic-riched phase (ORP) layer was constructed on Zn anode by introducing sodium anthraquinone-1-sulfonate (AQS) into the aqueous electrolyte with ethylene glycol (EG). In such an electrolyte, the zincophilic -SO 3 − groups of AQS molecules preferentially adsorb on Zn anodes, and stable chemical bonds are achieved between them. After that, the low-polarity and hydrophobic anthraquinone group in the AQS layer tends to repel H 2 O molecules. Simultaneously, more AQS and EG molecules are attracted and migrate toward AQS layer due to polar compatibility, constructing the AQS/EG-riched layer on the Zn anode by the interlocking effect among them.

We report the self-assembly of amphiphilic peptides I 3 H, designed with a modular structure featuring three consecutive isoleucine residues as a hydrophobic tail and a C-terminal histidine-based hydrophilic headgroup. Microscopic, neutron scattering, and spectroscopic techniques demonstrate that the designed peptides self-assemble into β-sheet nanofibrils, with their helix handedness exhibiting subtle pH-dependent inversion. pH titration, NMR, and molecular dynamics simulations reveal the underlying mechanism correlates with the protonation state of histidine and the molecular packing modes in β-sheet assemblies. The protonated histidine promotes antiparallel β-sheet packing at lower pH while its deprotonated state favors parallel packing when pH is increased. Strong π-π stacking interactions between deprotonated histidine side chains in parallel β-sheet arrangements drive chiral flipping of β-strands, ultimately inducing supramolecular helix inversion. Furthermore, such a pH-dependent helix inversion can be engineered by inserting the achiral and flexible glycine at the hydrophobic/hydrophilic interface, with I 3 GH assembly maintaining this effect while I 3 GGH assembly abolishing it.

  @article{ , abstract = {Electrocatalytic sulfion oxidation reaction (SOR) is a sustainable approach to treat sulfion-rich sewage for S recovery. Transition metal hydroxide (TMOH), utilized in various electrocatalysis, yet is clumsy in SOR due to overstrong adsorption toward S-containing intermediates from unsuitable electronic structure. Herein we report, for the first time, that the SOR performance of TMOH can be awakened by intercalation chemistry. Take Co(OH) 2 as a proof-of-concept demonstration, MoO 4 2− intercalated Co(OH) 2 2D nanosheet array is engineered, and presents remarkably enhanced SOR behavior with an ultralow potential of 0.29 V versus RHE to attain 100 mA cm −2 , a record Tafel slope of 27.7 mV dec −1 , and stable operation for 192 h without appreciable deterioration. The experimental and theoretical studies unveil that MoO 4 2− -intercalated nanoarray is advantageous for active site exposure, and boosting mass transport with enhanced sulfion enrichment and superhydrophilicity. Impressively, MoO 4 2− intercalation can manipulate electronic structure of Co(OH) 2 with downshift of d-band center, thereby weakening binding strength with HS − and S 8 , and decreasing the |ΔG s* |, eventually enhancing both activity and stability. Notably, such intercalation wake-up strategy for the SOR is general and can be extended to other oxometallate intercalated TMOH systems.

  @article{ , abstract = {Mechanophores (mechanosensitive molecules) are usually activated by pulling force transduced by polymer covalently attached to their structures. A variety of mechanophores have been described to date but many rely on a limited number of core structures. The diversity of products formed mechanochemically could be improved by promoting the scission of varied bonds within a single mechanophore. 4-membered rings are particularly suited for this as two sets of products can be obtained by formal retro-[2 + 2] cycloaddition depending on the pulling direction. This concept has been applied to a couple of mechanophores but the repositioning of the anchoring points often requires a redesign of the structures, and the pulling activation is not amenable to the release of the products. Here we show that the unique pushing activation of a rotaxane actuator enables the selective activation of covalent bonds parallel or perpendicular to the main chain in diazetidinone and β-lactam mechanophores. The selectivity depends on the orientation of the bulky substituents pointing toward or away from the incoming macrocycle. We were able to release ketene and triaryl imine/ethene molecules, and to generate imine, azobenzene, and isocyanate units. This alternative activation method demonstrates how to elicit new reactivity from known mechanophores and should inspire the design of new ones.

Our key innovation is the use of fluorinated tetrazole as a weak acid tecton and a tetra-substituted imidazole precursor devoid of active protons as the base. Single-crystal analysis and computational modeling reveal that the structural integrity of the synthesized POSs arises primarily from cation–anion interactions, with water confined as clusters in the pores, independent of hydrogen bonding with the scaffold. Robustness of the POS structure under aqueous and water-lean conditions is confirmed by X-ray and neutron scattering, as well as computational modeling, confirming preserved packing and crystal structures.

Achieving an ultralong service life, e.g., beyond 100 000 cycles, is highly desired for aqueous energy storage, which necessitates the precise cognition and modulation of the surface/interface microenvironment with prolonged cycling conditions. Herein, to address this issue, we for the first time engineer the competitive bonding and the electrochemical deep progression of NiCoCu medium-entropy hydroxides. The theoretical and experiment results indicate that Cu is prone to leaching from the medium-entropy hydroxides with cycling, which elevates the d/p-band centers to activate the lattice oxygen and Co atoms, triggering a Cu/Co dual-cation dissolution relay phenomenon. As-incorporated Co vacancies favor the β-to-γ phase transformation of the reconstructed structure, accompanied by the coordination oscillation and the production of ultrafine (∼1.9 nm) nanodomains with improved kinetics and stability. Consequently, capacity retention of 1485 C g −1 was achieved after 150 000 cycles for the reconstructed electrodes, which is superior to many state-of-the-art NiCo-based materials.

Experimental and theoretical studies on the Ni atom-based SACs showed that symmetry breaking raises the Ni d-band center, enabling a monodentate-to-bidentate Li 2 S 4 adsorption transition, which strengthens polysulfide adsorption and shifts the rate-limiting step from sluggish solid-solid transformation (Li 2 S 2 → Li 2 S) to a more favorable liquid–solid conversion (Li 2 S 4 → Li 2 S 2 ), effectively lowering the overall energy barrier of the SRR process.

  @article{ , abstract = {Electrocatalytic alkyne semi-hydrogenation (EASH) powered by renewable electricity using water as a hydrogen donor provides a sustainable alternative to conventional thermocatalysis.

Well-defined two-dimensional Cu nanosheets with exposed (111) facets achieve > 98% selectivity for electrochemical semi-hydrogenation of 4-aminophenylacetylene to 4-vinylphenylamine in a membrane electrode assembly reactor. The Cu nanosheets can also efficiently remove 1%–8% alkyne impurities in alkene and exhibit broad substrate scope, stereoselectivity, as well as operational stability. In situ Raman spectroscopy measurements reveal that, during the PCET-mediated EASH, the covalent adsorption of alkynes and their conversion to weakly bound planar intermediates facilitate the EASH process and suppress over-hydrogenation. Interfacial K + -structured and linearly hydrogen-bonded water species further enhance EASH selectivity via proton supply and steric modulation.

As a consequence, the photoluminescence of the mechanophore in THF solution and in solid films of a polyurethane containing the new motif is dominated by excimer emission. Stretching the polymer films causes an easily discernible change from bright yellow excimer to blue–green monomer-dominated emission. The ratio of excimer to monomer emission intensities traces the nonlinear stress–strain curves of the polymer well and is a good indicator for the macroscopically applied force. The reversibility of the mechanoresponse, theoretical analyses, and reference experiments with a similar mechanophore in which the emitters and the [2.2]paracyclophane core are connected by flexible linkers support the conclusion that the mechanoactivation is caused by distorting the molecule into a bent, more open conformation and not the scission of covalent bonds.

To overcome this limitation, we report herein a PCR-free SDM method that uses DNA-cleaving DNAzymes. Since these DNAzymes lack the capability of cleaving double-stranded DNA, we employed single-stranded DNAs as assisting DNAs to open superhelical plasmids, allowing the DNA-cleaving DNAzymes to cleave the plasmid. Such a system, named single-stranded DNA-assisted double-stranded DNA nicking by DNAzymes (DANDA), expanded the substrate scope of DNAzymes to double-stranded, superhelical plasmids. We showed that DANDA is highly customizable and target-specific, which allows successful generation of mutations on a plasmid containing PCR-incompatible repetitive sequences. By using solely unmodified DNA oligos that are more cost-effective and easier to prepare than other systems that employ either PNA or restriction enzymes, this DANDA system further expands the applications of DNA-cleaving DNAzymes in synthetic biology for different biochemical and biotechnological applications.}, archive = {J_ANGEW}, author = {Mingkuan Lyu and Linggen Kong and Xiangli Shao and Yi Lu}, doi = {10.1002/anie.202509127}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {37}, pages = {e202509127}, shortjournal = {Angew.

This behavior arises from inherent space charge layers that restrict Li⁺ transport under high current, and spatially heterogeneous active sites at the solid electrolyte–cathode interface, directly evidenced by small angle X-ray scattering (SAXS), which govern nucleation accessibility and promote site-selective Li 2 O 2 growth. Furthermore, higher current densities improve ORR and OER efficiency but accelerate anode degradation, while lower currents promote side reactions. These opposing effects result in a trade-off that defines an optimal discharge rate (0.1 mA cm⁻ 2 ) for maximizing cycle life. This study provides a new mechanistic perspective on discharge-driven processes in solid-state LOBs and offers practical guidelines for performance optimization in future high-energy battery systems.}, archive = {J_ANGEW}, author = {Xiaozhou Huang and Matthew Li and Yanan Gao and Moon Gyu Park and Shoichi Matsuda and Khalil Amine}, doi = {10.1002/anie.202507967}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {37}, pages = {e202507967}, shortjournal = {Angew.

Here, we report a dual-functional covalent organic framework (COF), named Ni–DAPTO, designed to improve both Zn 2+ storage on the cathode and zinc deposition kinetics on the anode. The incorporation of Ni coordination centers achieves an expected low energy gap, enhancing the intrinsic conductivity, while selectively guiding uniform Zn 2+ deposition. As a result, the Ni–DAPTO cathode demonstrated superior cycling stability and rate performance, retaining a specific capacity of 127.0 and 119.7 mAh g −1 at 0.5 and 10.0 A g −1 , respectively after 10 000 cycles. Besides, when employed as artificial solid electrolyte interphase (SEI), Ni–DAPTO can improve zinc utilization and inhibit dendrite formation.

Despite extensive efforts, current chemicals for biofilm eradication remain insufficient, with the reliance on single-structure antimicrobials further exacerbating resistance.

However, the biofilm-eradicating potential of spiropyran derivatives remains unverified, while their application is hindered by limited fatigue resistance, suboptimal foliar affinity, and reliance on UV-induced isomerization, all of which are incompatible with sustainable agriculture.

Here, we develop a rationally designed three-armed diazo crosslinker ( 3G ) for nondestructively patterning various chemically sensitive luminescent NPs with high resolution (down to nanoscale) and high fidelity. The key points of the 3G design include (i) shielding aliphatic C─H bonds, (ii) extending the distance between active sites, and (iii) introducing more crosslinkable moieties. Thanks to the low UV exposure dose (18 mJ cm −2 , in stark contrast to 200–500 mJ cm −2 for diazirine-based crosslinkers) required for sufficient crosslinking, mild photochemistry of 3G , and proper alignment of energy levels between 3G and NPs, the 3G -based patterning method can fully preserve the structural and photophysical properties of both upconverting NPs and perovskite quantum dots, as reflected by their unchanged emission peak/lifetime and high quantum yield retention (90%).

Recently a promising family of photoswitches based on the rhodanine motif was described. Here, the photophysics of a typical example are investigated by ultrafast UV and IR spectroscopy and quantum chemical calculations. Remarkably, the photophysics are very different to and more complex than those of closely related monomethine photoswitches, which relax by ultrafast internal conversion to the electronic ground state. In the rhodanine photoswitch, the allowed Franck–Condon excited state also relaxes on a sub-picosecond timescale, but the ground state is repopulated only after several hundred picoseconds. Instead, the Franck–Condon state relaxes through (at least) two intermediate states. These states are characterized by transient spectroscopy, and the reaction pathway is modeled by quantum chemical calculations. Comparison of calculated and measured IR data suggests that a triplet mediated isomerization pathway is responsible for the slow excited state dynamics. The triplet state is rapidly populated via coupling of a nearly degenerate nπ * state populated by ultrafast internal conversion from the bright ππ * state.

While significant advancements have been achieved in separating H 2 S from CH 4 , the selective removal of H 2 S from CO 2 remains a formidable challenge due to their similar physicochemical properties. Herein, we report a breakthrough strategy utilizing reversible nucleophilic addition reaction between carbonyl group and H 2 S, departing from conventional acid-base interaction-based liquid-phase capture processes. Through comprehensive characterization using nuclear magnetic resonance (NMR) and Fourier transform infrared (FT-IR) spectroscopy, we confirmed the formation of nucleophilic addition products between the designed carbonyl-functionalized ionic liquids (ILs) and H 2 S. Dispersion-corrected DFT calculations revealed that the nucleophilic addition products facilitate secondary H 2 S capture through two distinct approaches: 1) conformational matching and 2) dissociation of H 2 S into [HS]⁻ species. The unique cascade H 2 S sorption mechanism demonstrates exceptional affinity for H 2 S, endowing the [6ca]-derived ILs with unprecedented high H 2 S capacities and record-breaking H 2 S/CO 2 selectivities (67–89 at 1.0 bar and 229–319 at 0.1 bar), surpassing previously reported values. Combined with energy-efficient regeneration cycles, these findings establish a new paradigm for H 2 S/CO 2 separation with significant potential for natural gas valorization.}, archive = {J_ANGEW}, author = {Mingzhen Shi and Guoao Li and Hangzhi Wu and Hailong Ning and Hongchao Lan and Xiaomin Zhang and Shuhua Li and Youting Wu}, doi = {10.1002/anie.202504337}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {37}, pages = {e202504337}, shortjournal = {Angew.

  @article{ , abstract = {The secondary structures of polymers significantly influence their properties; however, understanding and modulating polymer conformations remain substantial challenges. Particularly, the β-turn conformation, which is prevalent in proteins, has not been reported in synthetic polymers due to its unclear formation mechanism and extremely poor stability. Additionally, there is a lack of visualization techniques to track conformational and functional transitions in polymers. Here, we designed and synthesized a novel tetraphenylethylene (TPE)-decorated poly(L-cysteine) derivative. Utilizing thioether oxidation as the driving force and strong aromatic-aromatic interactions between TPE molecules as stabilizing mechanism, we reported for the first time a conformational transition from β-sheet to β-turn in polymers. This transition not only significantly enhances fluorescence intensity but also induces chirality and circularly polarized light (CPL) of TPE, providing a new dual-modal approach to real-time monitoring of conformational changes of polymer chains. Furthermore, the conformational transition can trigger specific drug release, with the release process visualized and quantitatively analyzed through fluorescent colors. Such conformation-mediated structural and functional transformations hold significant potential for specific drug delivery and theragnosis of diseases such as cancer.}, archive = {J_ANGEW}, author = {Zifen Li and Yang Liu and Yiwei Wang and Yi Zheng and Chuan Peng and Zuojie Wang and Yeqiang Zhou and Xiaohan Dong and Mingming Ding}, doi = {10.1002/anie.202503875}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {37}, pages = {e202503875}, shortjournal = {Angew.

Here, we report a facile yet effective biomineralization strategy to construct nanovaccine (OVA-ATV@MnO₂) that co-delivers ovalbumin (OVA) and atorvastatin (ATV) within MnO₂ matrix. The ATV-mediated nanovaccine reprograms endosomal trafficking by inhibiting the mevalonate (MVA) pathway, thereby delaying endosomal maturation and preventing antigen diversion to degradative lysosomes. This intervention significantly enhances antigen preservation and MHC-I presentation in DCs. Simultaneously, the MnO₂ framework not only stabilizes the vaccine nanostructure but also releases Mn 2 ⁺ ions as an adjuvant to potently activate the cGAS-STING pathway, amplifying DC maturation and antitumor T-cell priming. In vivo studies demonstrate that the nanovaccine induces robust tumor regression, suppresses metastasis, and establishes durable prophylactic immunity.

More intriguingly, the glycoconjugated triplex metallohelice [Fe 2 L Δ-f 3 ] 4+ (Δ-f) can enantioselectively stabilize Sox2G4. Sox2G4 stabilization induced by [Fe 2 L Δ-f 3 ] 4+ (Δ-f) rather than Λ-f results in inhibition of Sox2 expression both in mRNA and protein levels in breast CSCs and decreases the cell viability and stemness of breast CSCs.

The acceleration effect depends on the steric hindrance and basicity of the additional Lewis-basic sites, located at remote positions to the C─H bond to be deuterated.

  @article{ , abstract = {Protein-based nanocarriers bear highly desirable properties such as biodegradability and the ability to facilitate passage through biological barriers such as the blood–brain-barrier. Using modular protein engineering, we develop a strategy for iteratively improving the delivery efficacy of hydrophobic small molecules for the treatment of glioblastoma multiforme (GBM). By increasing the multiplicity m of the coiled-coil and RGD peptide targeting regions from 1 to 2, we can increase both the hydrodynamic micellar size and drug loading capacity of the targeted multidomain protein assembly (TMPA) relative to its predecessor thermoresponsive assembled protein (TRAP). An upper limit of m is likely determined by steric interactions. TMPA shows a 1.7-fold increase in doxorubicin (Dox) encapsulation compared to TRAP and demonstrates a 1.3-fold improvement in uptake by U87 human GBM cells. Near-infrared (NIR) dye-labelled TMPA (NIR-TMPA) is intravenously administered to mice orthotopically implanted with GBM cells and to control mice. Pharmacokinetic analysis using a 2-compartment pharmacokinetic model reveals a significantly prolonged distribution-phase (short-phase) half-life in tumor-bearing mice compared to control, while the elimination-phase (slow-phase) half-life remains comparable between groups. This suggests altered early-phase kinetics likely due to tumor-associated sequestration or retention. The resulting increased area under the concentration-time curve (AUC) in tumor-bearing mice supports enhanced accumulation or slower clearance.

Engineering this catalytically active periphery, where kinetically relevant surface intermediates are efficiently turned over, offers a pathway to optimized performance, yet it remains challenging due to the need for precise control over nanospatial catalyst features. Herein, we address this subject for the relevant case of methanol synthesis by CO 2 hydrogenation on Cu/ZrO 2 catalysts. The methanol synthesis rate reaches a maximum at a surface-to-surface Cu interparticle distance of ca. 15 nm. Operando modulation–excitation diffuse reflectance infrared spectroscopy reveals that this optimal spacing maximizes the fraction of surface-bound HCOO* intermediates, stabilized on coordinatively unsaturated Zr(IV) Lewis acid sites on the ZrO 2 support, which are dynamically involved in catalysis. This particle spacing represents a shift in the reaction's kinetic control regime and the apparent activation energy for methanol synthesis.

A comprehensive DFT study of the plausible reaction mechanisms indicates that the enhanced activity of 1 can be attributed to the presence of the [Co(CO) 4 ] – anion, which enables a frustrated Lewis pair (FLP) mechanism that provides a low energy pathway for the heterolytic splitting of the Si─H bond. The reaction mechanism entails the coordination of the hydrosilane to the Co(I) center upon decoordination of the amine functionality of the PN H P ligand, followed by heterolytic splitting of the Si─H bond with the participation of the Co(I) and Co(–I) centers. Then, the PhSiH 2 group at the Co(–I) center is transferred to the oxygen atom of a methanol molecule, which affords the [H 2 SiPh(HOMe)] + cation, regenerating the [Co(CO) 4 ] – species. [H 2 SiPh(HOMe)] + protonates the hydride at the Co(I) center, leading to the formation of H 2 and the corresponding silyl ether. Alternative reaction pathways, including alternative ionic mechanisms or NH-assisted bifunctional mechanisms, result in higher activation energies.}, archive = {J_ANGEW}, author = {Ana Luque-Gómez and Daniel Barrena-Espés and Pilar García-Orduña and Andrea Pérez-García and Miguel A.

  @article{ , abstract = {Achieving ultrahigh birefringence in UV-transparent materials remains fundamentally constrained by the trade-off between strong optical anisotropy and wide bandgap transparency. Herein, we report a dual-sided multidentate coordination (DMC) strategy to construct two butterfly-shaped UV organic–inorganic hybrid crystals—(C 6 H 4 NO 2 ) 2 SbF (PCSF) and (C 10 H 6 NO 2 ) 2 SbF (QCSF)—in which planar π-conjugated bidentate ligands symmetrically chelate stereochemically active lone pair (SCALP) Sb 3+ centers. This coordination architecture enforces coplanar alignment of optical functional units and promotes dense π–π stacking, thereby significantly enhancing macroscopic birefringence. Notably, QCSF achieves a record-high birefringence of Δ n = 0.87 at 546 nm, surpassing all previously reported lone-pair-containing halide crystals with UV transparency. The exceptional optical performance is attributed to the unique [SbN 2 O 2 F] coordination geometry, near-planar molecular configuration, and extended π-electron delocalization.

Through three rounds of iterative optimization combining RL predictions with human chemical intuition, we identified elastomers with more than double the average toughness compared to the initial training set.

  @article{ , abstract = {Aggregation-induced emission (AIE) luminogens, exemplified by tetraphenylethylene (TPE), exhibit enhanced fluorescence in aggregated states and have promising applications in display, photodetectors, fluorescent probes, bioimaging, and biomedicine. This study investigates the influence of varying degrees of deuteration on the photophysical properties of TPE across different aggregation states. Through the synthesis of partially and fully deuterated TPE derivatives (TPE-5d, TPE-10d, and TPE-20d), combined with steady-state fluorescence spectroscopy, time-resolved fluorescence measurements, transient absorption spectroscopy, and density functional theory (DFT) calculations, we elucidate the dual role of deuteration in modulating nonradiative decay pathways. In loosely packed nanoaggregates, increased deuteration enhances photoluminescence quantum yields (PLQY) and extends fluorescence lifetimes by reducing internal conversion rates. Conversely, in tightly packed crystalline states, deuteration leads to decreased PLQY and shortened lifetimes, attributable to the Duschinsky rotation effect (DRE), which enhances inter-mode coupling and internal conversion. Additionally, deuteration significantly prolongs the operational lifetime of blue organic light-emitting diode (OLED) devices, doubling the device lifespan in TPE-20d compared to TPE. This work underscores the necessity of evaluating structure–property relationships at the aggregate level, rather than solely at the molecular level, to fully comprehend and optimize AIE phenomena.

  @article{ , abstract = {A new empirical electrophilicity reactivity parameter, E RB , was developed based on the rotational barriers of a series of N -phenylimide molecular rotors containing various electrophilic groups. In the bond rotation transition state, these electrophilic groups form close contact with an electronegative C═O oxygen. Thus, strong electrophilic groups significantly lowered the rotational barrier. As a result, the rotational barriers were inversely correlated with the strengths of the electrophiles. The rotational barriers were measured by dynamic NMR (EXSY), enabling the quantification across a wide range of types of electrophiles. Computational analysis confirmed that the observed variations arose from intramolecular interactions in the transition state, where the C═O oxygen served as a probe of both the electrophilic group's electrostatic potential and steric accessibility. By simultaneously capturing attractive and repulsive transition state interactions, E RB provides an effective means of predicting electrophilicity and reactivity trends across a broad range of electrophiles and reaction types. The utility of E RB was initially validated using a series of rotors containing Michael addition electrophiles, followed by broader application to a diverse array of reactions involving sp 3 and sp 2 electrophiles, including S N 2, S N Ar, Pd-oxidative addition, and Sonogashira reactions.}, archive = {J_ANGEW}, author = {Hao Liu and Xiaolong Huang and Binzhou Lin and Harrison M.

The composite showcases outstanding CO 2 conversion performance across a wide pH range, attaining remarkable Faradaic efficiency for formate (FE formate ) of 96.48% (at ultralow potential of −0.5 V versus RHE) and 92.26% in alkaline and neutral electrolytes, along with exceptional long-term stability over 150 h.

  @article{ , abstract = {Integrating different polymer types into a unified system in a thoughtful manner leverages their complementary advantages, providing a promising strategy for developing high-performance materials. Mechanically interlocked polymers (MIPs), characterized by their unique spatial entanglement, exhibit distinctive performance advantages, yet their potential to expand material properties through rational integration with other polymer architectures presents substantial opportunities for continued investigation. Herein, we report a coherent integration of covalent polymers (CPs) and mechanically interlocked polymers through sequential orthogonal polymerizations, developing a novel synergistic covalently and mechanically interlocked polymer (CMIP) featuring both structural stability and force-induced dynamics. Compared to its structurally similar but noninterlocked control sample, CMIP demonstrates markedly enhanced thermomechanical stability and performance recovery, achieving a 93.4% recovery efficiency at 100% strain after just 5 min of rest, in contrast to 59.7% for the control. This remarkable stability and recovery result from the synergistic interplay between the covalent polymer framework and the interlocked structure, which work in tandem to preserve network integrity and enable rapid host−guest reformation. Notably, despite this significant improvement, CMIP retains a comparable damping capacity (91% versus 87%) and material toughness (14.8 versus 15.1 MJ m −3 ), owing to the efficient energy dissipation mechanisms enabled by host−guest dissociation and subsequent sliding motion.

By virtue of the unique synergistic catalysis between atomically dispersed Ni species and precisely engineered Ov sites, the Ni 1 /TiO 2- X catalyst achieves a remarkable urea production rate of 15.73 µmol g cat. −1 h −1 . Further mechanistic studies reveal that the atomically dispersed Ni sites facilitate N 2 adsorption and activation, generating *N 2 species, while the adjacent Ov sites activate CO 2 to form *CO intermediates. More intriguingly, the *CO species can migrate from the Ov site to the nearby Ni active centers, where they spontaneously undergo thermodynamic coupling with *N 2 to form a “tower-like” urea precursor (*NCON* intermediate), subsequently converting to urea.

Owing to the narrow bandgap of CuO-PMA, the electron holes are rapidly separated under US irradiation, then quickly migrate through the sub-nanosheet structure to the surface to catalyze the formation of singlet oxygen (¹O₂) and superoxide anions (•O₂⁻), while simultaneously consuming glutathione (GSH). Furthermore, leveraging electron delocalization properties, US triggered the directional migration of electrons in CuO-PMA, facilitating the Cu(II)-to-Cu(I) transition to enhance hydroxyl radical (•OH) production. The ROS burst together with ions and h + -mediated GSH exhaustion synergistically provokes mitochondrial oxidative stress, activating the caspase-1/GSDMD axis to induce pyroptosis. In vivo experiments demonstrated that CuO-PMA significantly inhibited tumor growth and showed excellent antitumor immunotherapeutic effects.

  @article{ , abstract = {Inositol pyrophosphates (PP-InsPs) are highly phosphorylated signaling molecules that regulate diverse cellular processes, including phosphate homeostasis and energy metabolism across species. Despite extensive research on well-characterized exhaustively phosphorylated PP-InsPs, such as 5-PP-InsP 5 (5-InsP 7 ) and 1,5-(PP) 2 -InsP 4 (1,5-InsP 8 ), the functional relevance of less abundant not fully phosphorylated isomers, remains largely unknown. In this study, we synthesized all unsymmetric 5-PP-InsP 4 isomers in enantiopure form and assigned their structures using 31 P-NMR analysis in combination with a chiral solvating agent. Additionally, we developed 18 O-labeled PP-InsP 4 standards for mass spectrometry in combination with capillary electrophoresis (CE-MS), enabling the assignment of PP-InsP 4 in Arabidopsis thaliana under phosphate starvation. Our findings show that the previously detected, phosphate starvation-induced root-specific PP-InsP 4 isomer does not match any 5-PP-InsP 4 isomer, contrary to previous suggestions, thus indicating an alternative phosphorylation pattern. Enzyme assays further demonstrate that Arabidopsis ITPK1 selectively phosphorylates [6-OH]-InsP 5 and [3-OH]-InsP 5 at the 5-position, while other InsP 5 isomers remain unchanged. This suggests that an unidentified enzymatic activity is involved in the formation of the elusive root PP-InsP 4 species.

Efficient peptide synthesis relies on intricate domain interactions, whose underlying principles remain poorly understood. The communication-mediating (COM) domains facilitate interactions between separate NRPS subunits. For unknown reasons, COM domains co-occur with epimerization (E) domains, are partially embedded within the adjacent condensation (C) domains and can also be found as internal cis -COM domains. These features set COM domains apart from other docking domains. We present the first crystal structure of a cis -COM domain within an E-COM-C domain arrangement from modules 4 and 5 of bacitracin synthetase 3 (BacC). The structure reveals a compactly folded COM domain sandwiched between E and C domains, suggesting a role of the COM domain in orienting these domains for efficient peptidyl carrier protein (PCP) shuttling. Through mutational analyses, dipeptide formation assays, and proximity-dependent photo-crosslinking experiments, we investigated both cis - and trans -COM domains and provide evidence supporting a principal role of COM domains as scaffolds of NRPS architecture.

  @article{ , abstract = {Aqueous Zn-ion batteries (AZIBs) are promising candidates for next-generation energy storage. However, their application is hindered by Zn anode instability and reduced ionic conductivity at low temperatures. Here, we identified two decisive factors for low-temperature performance and anode stability of batteries: tetrahedral entropy and cation entropy. The former is closely related to antifreezing ability of electrolyte, while the latter is associated with the desolvation kinetics of Zn 2+ . We propose an effective strategy to balance the above two thermodynamic quantities by precisely tuning the molar fraction of the 1,3-butanediol (BDO) cosolvent with notable glass-forming ability. BDO enhances the tetrahedral entropy due to the disruption of the hydrogen-bond networks among water molecules, decreasing the solid–liquid transition temperature from −16.4 to −101 °C. Additionally, BDO modifies the solvated structure of Zn 2 ⁺ to limit the active water content, thus suppressing by-reactions at the electrode/electrolyte interface. The optimized electrolyte enables long-term cycling of Zn||Zn symmetric cells for over 4000 h at −40 °C under 0.1 mA cm −2 /0.1 mAh cm −2 , and renders PANI||Zn full cells capable of working across a broad temperature range (−40 °C to 60 °C).

In this study, we unveil the crucial role of PdAu/CeO 2 catalysts in enabling selective methane transformation under mild conditions, using only water as the sole oxidant. Through a combination of experimental techniques, including XPS and catalytic testing, alongside density functional theory (DFT) calculations, we demonstrate that a Pd 0.3 Au 0.7 /CeO 2 catalyst, which predominantly exposes isolated Pd atoms, achieves remarkable methanol selectivity (∼80%) at 500 K with a 1:1 methane-to-water ratio. While Pd/CeO 2 efficiently activates methane, its tendency for overreaction leads to complete methanol decomposition, thereby limiting selectivity. Alloying Pd with Au on ceria mitigates this over-reactivity, preventing methanol degradation while maintaining sufficient catalytic activity. The PdAu/CeO 2 composite exhibits a synergistic effect: Pd in contact with the ceria support facilitates methane activation and water dissociation, while Au fine-tunes reactivity to promote methanol formation.

Metal coordination increased the redox potential of cyclam-SS, activating it as an oxidant.

Furthermore, cyclam-SS protected cultured cells from copper-induced stress. Thus, we demonstrated the induction of the stress-responsive up-regulation process by a bifunctional folding promotor controlling the folding status of biologically important proteins under metal-induced stress.

  @article{ , abstract = {In solid-state lithium-ion batteries, the fraction of active materials involved in electrode electrochemistry reduces with the increase of electrode thickness. Conventional wisdom suggests that the degree of reaction linearly decreases toward the current collector as in lithium-ion batteries, which is, however, limited by the high difficulty of experimental capture of operando charge and mass transport. Electrode dynamics simulations can provide space visualization but are usually based on simplified models. Herein, we build digital-twin electrodes with digital-space voxel microstructure based on synchrotron tomography, which transforms the electrode architecture from real space to digital space for the construction of precision models. From the digital model-driven simulation, we find an “lithium trapping” effect, stemming from susceptible lithium stuck in the solid electrolyte, triggers an inadequate reaction of the intermediate region of electrodes. Then, we construct locally accelerated ion paths activating the lithium trapping, indicating that this strategy can significantly guide the sustainable battery design for next-generation energy storage.}, archive = {J_ANGEW}, author = {Yecai Sun and Yanbin Ning and Zhuomin Qiang and Lizhi Xiang and Qingsong Liu and Chaoqun Zhang and Guoce Quan and Yan Zhang and Biao Deng and Geping Yin and Tiefeng Liu and Jiajun Wang and Shuaifeng Lou}, doi = {10.1002/anie.202502169}, journal = {Angewandte Chemie International Edition}, month = {9}, number = {36}, pages = {e202502169}, shortjournal = {Angew.

Electrocatalytic urea production from carbon dioxide (CO 2 ) and nitrate (NO 3 − ) under ambient conditions offers a sustainable alternative, yet challenges persist due to variable NO 3 − concentrations and competing side reactions. Herein, we propose porphyrin metal-organic framework (PMOF) and Cu-porphyrin MOF (Cu-PMOF) catalysts for NO 3 − concentration-adaptive urea synthesis. Density functional theory (DFT) calculations reveal that PMOF weakly adsorbs *NO 2 via hydrogen bonding, favoring its coupling with *CO 2 , while Cu-PMOF strongly binds *NO 2 at Cu sites, facilitating spontaneous *NO/*CO coupling to form *OCNO intermediates under dilute NO 3 − conditions. Experimentally, PMOF achieves a urea yield of 28.6 µmol h −1 mg cat −1 and a Faradaic efficiency (FE) of 23.1% in 0.1 M NO 3 − , whereas Cu-PMOF outperforms in 0.05 M NO 3 − with a yield of 25.5 µmol h −1 mg cat −1 and FE of 52.7%.

  @article{ , abstract = {Proton exchange membrane fuel cells (PEMFCs) show great potential for energy conversion, but their platinum-based hydrogen oxidation reaction (HOR) catalysts are easily and irreversibly poisoned by trace impurities like H 2 S, causing performance degradation with unclear mechanisms. Here, combining in situ Raman spectroscopy with theoretical calculations, we found that on pure Pt surfaces, H 2 S dissociates into S* and HS* intermediates that occupy active sites of continuous Pt atoms in an acidic solution under 50 ppm H 2 S/H 2 atmosphere. However, on PtRu alloy surfaces, while *OH species were observed on Ru sites, no sulfur-containing species were detected on Pt sites. Comparative experiments revealed that the sulfur-related Raman peaks of PtRu exhibited a redshift compared to Pt, indicating that Ru alloying weakens the *S adsorption on Pt sites through electronic effects. These results demonstrate that Ru not only creates discontinuous Pt sites to block sulfur adsorption but also significantly weakens sulfur binding through electronic modulation. Based on these insights, small-sized site-blocking PtRu/C catalysts were developed, exhibiting only 9.2% activity decay after 700s in 50 ppm H 2 S/H 2 atmosphere, a 4.3-fold improvement over commercial Pt/C catalysts (39.3% decay).

We employed the density functional theory (DFT) to calculate the hydrogenation of acetylene on face-centered cubic metals and copper-based alloys. Microkinetic modeling identifies changes in the rate-determining steps of different alloys as electronegativity decreases. We then constructed the volcano plot for the adsorption energy toward C 2 H 2 and the reaction rate, which predicted that Cu 3 Au is the best candidate alloy for the C 2 H 2 semi-hydrogenation. Both extensive prior research and our experimental findings validated our volcano plot. Notably, our work points out the two key determinants of the ER mechanism: atomic activation and steric hindrance. For metals with weaker adsorption, steric hindrance primarily obstructs the ER mechanism, while for metals with stronger adsorption, the ER mechanism is hindered due to the challenge of atomic activation.

  @article{ , abstract = {Electrocatalytic nitric oxide reduction reaction (NORR) for ammonia (NH 3 ) synthesis represents a sustainable strategy that simultaneously realizes the nitrogen cycle and resource integration. The key issue hindering the NORR efficiency is accelerating proton (*H) transfer to facilitate NO hydrogenation while inhibiting the hydrogen evolution reaction (HER). Herein, we demonstrate an interface-engineered sulfur-mediated Cu@Co electrocatalyst (S-Cu@Co/C) that boosts NORR performance through dual modulation of electronic structure and proton transfer on active sites. A comprehensive program of experimental and theoretical calculations was employed to discover that sulfur incorporation induces electron redistribution in the Cu–Co interface, creating electron-rich sulfur and electron-deficient metals. This electronic configuration synergistically enhances NO adsorption on Cu sites and promotes water dissociation on Co sites. More critically, sulfur could direct the rapid transfer of *H from Co to Cu sites, thereby accelerating the NO hydrogenation and suppressing HER. Consequently, S-Cu@Co/C achieves an NH 3 yield rate of 655.3 µmol h −1 cm −2 in a flow cell and a Faradaic efficiency of 92.4% in an H-cell.

Although structurally similar to tryptophan 2,3-dioxygenase (TDO), which initiates l -tryptophan catabolism via dioxygenation, MarE exhibits distinct reactivity modulated by ascorbate. While ascorbate has no effect on TDO, it promotes selective monooxygenation by MarE. In its absence, MarE favors dioxygenation and formation of pyrroloindoline products, revealing latent catalytic versatility. Active-site loop sequences differ between the two enzymes, SLGGR in MarE versus GTGGS in TDO, prompting loop-swapping experiments to probe structure-function relationships. Substituting GTGGS in TDO to MarE-like sequences (GTGGA or SLGGS) shifted reactivity toward monooxygenation and formation of C3-hydroxylated, non-oxindole products that underwent further cyclization into tricyclic structures. Conversely, replacing SLGGR in MarE with GTGGS resulted in enhanced C2,C3-dioxygenation nearly 4-fold.

  @article{ , abstract = {Four-electron iodine conversion chemistry (I −/ I 2 /I + ) endows zinc–iodine batteries with competitive energy density. The stability of I + conversion relies on its interaction with sufficient nucleophilic species (e.g., Cl − , Br − ). However, under high iodine loading, nucleophilic species fail to afford sufficient coordination strength and number within thick iodine cathode to stabilize I + , thus compromising the high-voltage plateau and capacity. Here, we effectively spatially confine nucleophilic species (Cl − ) on the cathode by ─C─N + -induced localized electric field (LEF) microenvironment in polyquaternary ammonium iodide (PDDA-I). Spatial confinement maximizes Cl − concentration on the cathode ensuring highly reversible I 0 /I + conversion, even in the low-concentrated ZnCl 2 addition and high iodine loading. Importantly, the dynamically regulated Cl − maintains a balance with iodine species at the ─C─N + sites during cycling, effectively limiting the shuttling effect of polyiodides. Consequently, even adopting a high iodine loading of 16.03 mg cm −2 , the PDDA-I still maintains a distinct four-electron-conversion dual voltage plateau with a remarkable capacity of 4.97 mAh cm −2 . An impressive lifespan of 10 000 cycles is achieved at 12.6 mg cm −2 with a capacity decay of 0.0012% per cycle, exceeding conventional iodine cathodes by 20-fold.

Significantly, the proposed ECL enhancement strategy effectively enhances the ECL emission of metal nanoclusters (M NCs) over a wide wavelength range and advances a new path for other tunable nanomaterials to enhance the ECL emission of M NCs, which is expected to be applied to in the field of multispectral ECL imaging, multimodal optoelectronic devices, and spectrum-resolved multiplexed biosensing systems.}, archive = {J_ANGEW}, author = {Zhao-Chen Shen and Yi-Fei Chen and Ya-Qin Chai and Jia-Li Liu and Ruo Yuan}, doi = {10.1002/anie.202509884}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {35}, pages = {e202509884}, shortjournal = {Angew.

  @article{ , abstract = {Global energy and environmental crises have stimulated increased efforts toward converting CO 2 into valuable chemicals or energy substance. Inspired by natural chloroplasts and mitochondria, we build an innovative polydopamine-armored multiple enzyme microreactor for co-immobilizing glyceraldehyde-3-phosphate dehydrogenase (GAPDH), 3-phosphoglyceric phosphokinase (PGK), formate dehydrogenase (FDH), and ATPase-incorporating proteoliposome, providing spatially confined microenvironments akin to natural systems. Within this microreactor, GAPDH and PGK catalyze the conversion of glyceraldehyde 3-phosphate to 3-phosphoglyceric acid, reducing β-nicotinamide adenine dinucleotide (NAD + ) to NADH and generating a proton influx that drives ATP synthesis. The microreactor possesses strong affinity for CO 2 , combined with FDH, facilitates the reduction of CO 2 to formic acid, oxidizing NADH back to NAD + and enabling the recycling of the NAD + /NADH redox couple. This process further boosts ATP production by contributing additional protons. Such microreactor adeptly orchestrates the chloroplast's enzymes to fix CO 2 and the mitochondrion's enzymes to synthesize ATP into a unified artificial biomimetic system, effectively replicating the glycolysis process to simultaneously achieve CO 2 fixation, NADH regeneration, and ATP synthesis. This strategy not only holds great potential to inspire significant design innovations for more efficient ATP synthesis from low-value substances but also greatly expands the application scenarios for biomolecular motors.}, archive = {J_ANGEW}, author = {Yang Xu and Fanchen Yu and Yi Jia and Xuanze Meng and Rong Shu and Hong Li and Zibo Li and Junbai Li}, doi = {10.1002/anie.202509835}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {35}, pages = {e202509835}, shortjournal = {Angew.

  @article{ , abstract = {The unique structure–function relationship of the ribofuranose ring in RNA has inspired various chemical pathways to select for the ribofuranose form (over the ribopyranose form), especially in a prebiotic context. Herein we show that the reaction of diamidophosphate (DAP) with the four pentoses—ribose, arabinose, xylose, and lyxose—naturally selects the ribofuranose form more efficiently when compared to the other three pentoses. All four pentoses form the initial diamidophosphate-adduct; however, ribose undergoes rapid conversion to ribofuranose-1,2- and 2,3-cyclicphosphate products, while the other three pentoses show significant accumulation of the initially formed DAP-adducts and slow conversion to the cyclicphosphate products. Arabinose and xylose show a distribution between furanose- and pyranose-1,2-cyclicphosphate products, while lyxose forms the furanose-1,2- and pyranose-2,3-cyclicphosphate products. This trend is also manifested when starting from a mixture of pentoses where ribofuranose 1,2-amidocyclicphosphate dominates the product distribution. Such selection for ribofuranose among pentoses by phosphorylation i) provides another venue of how a ribofuranose structure can selectively emerge through abiotic chemical reaction suitable for elaboration toward RNA and ii) adds to the body of experimental work addressing the chemical origin of RNA.}, archive = {J_ANGEW}, author = {Harold A.

  @article{ , abstract = {A sustainable strategy for simultaneous pollutant removal and carbon sequestration is offered by the peroxymonosulfate (PMS)-mediated electron transfer mechanism. However, it remains challenging to achieve catalysts with durable and high activity. A novel catalyst design strategy leveraging boron doping that induces long-range electronic polarization to precisely modulate PMS complexation dynamics on single-atom catalysts (SACs) is proposed in this study. It is demonstrated that B-doping induces asymmetric Fe-N 5 coordination at the atomic iron centers (Fe SA -BNC) while creating electron-enriched carbon auxiliary sites. The electron distribution is synergistically optimized by this dual-site configuration through lowering the d-band center and establishing a polarized charge transfer pathway. Complexes with enhanced oxidation potential are generated by the engineered Fe SA -BNC/PMS, redirecting bisphenol A degradation from conventional radical-mediated mineralization to an interfacial polymerization pathway via outer-sphere electron transfer.

In this work, a new spinel-type high entropy oxide with Lewis basicity (LB-HEO) was synthesized through a Joule-heating method. O L was activated by regulating the tetrahedral site-O L -octahedral site (M Td -O L -M Oh ) units in the spinel-type HEO, enhancing the LB. Used as a cathode catalyst for LOBs, LB-HEO could attract Li + and increase the disorder in discharge product, lithium peroxide (Li 2 O 2 ), promoting the delithiation process and the interfacial charge transfer at the LB-HEO|Li 2 O 2 interface. The activation energy of interfacial charge transfer was significantly reduced from 63.5 to 22.4 kJ mol −1 .

To address these limitations, we design a coordination-unsaturated CuAg bimetallic catalyst with cross-linked nanochains (Cu 0.5 Ag CNCs), which synergistically regulates proton dynamics, maintaining high activity from 0.1 to 0.6 A cm −2 and achieving an ethylene Faradaic efficiency of 95.1% at 0.5 A cm −2 . Mechanistic studies reveal that the introduction of Cu makes the d-band center in Cu 0.5 Ag CNCs upshift toward the Fermi level, strengthening orbital coupling with C 2 H 2 and creating a high *H demand surface. In situ spectroscopic and density functional theory analyses demonstrate that coordination-unsaturated Cu-Ag interfacial sites promote spontaneous C 2 H 2 hydrogenation, especially bypassing formation barriers of *C 2 H 2 and *C 2 H 3 . This thermodynamic superiority originates from sufficient proton supply and exothermic *H consumption for C 2 H 2 hydrogenation. Furthermore, the catalyst enables a Zn-C 2 H 2 battery with a power density of 2.12 mW cm −2 , showcasing dual functionality in electrosynthesis and energy storage.

Currently, no approved therapies specifically target advanced liver fibrosis, thus exploring the molecular mechanisms underlying liver fibrosis has become crucial. Previous studies have highlighted significant controversy regarding the role of ferroptosis in liver fibrosis. Given that reactive oxygen species (ROS) serve as key mediators to both processes, ROS may serve as a molecular nexus connecting ferroptosis and liver fibrosis. To comprehensively elucidate the molecular network involving ROS and ferroptosis in liver fibrosis, we designed and synthesized the first multi-functional “cocktail” fluorescence probe, FP-ROS, enabling highly sensitive and selective simultaneous imaging of O 2 •− , H 2 O 2 , and ONOO − . FP-ROS was successfully employed to assess ferroptosis levels in the livers of fibrosis mice following drug intervention.

To effectively address this issue, Ru single atoms with different loading are anchored on the graphene-like framework and tungsten carbide substrate (WC 1-x ) to investigate the synergistic effect among different local configurations. X-ray absorption spectroscopy demonstrated that the loading of Ru atoms critically governs the interatomic distance between adjacent metal active sites at second shell coordination. In situ Raman spectroscopy shows that WC 1-x nanoparticles can break the hydrogen bond network by reorienting H 2 O molecule adsorption and promoting the availability of active H 2 O among electrode-electrolyte interface.

Furthermore, Ab initio molecular dynamics simulations reveal the spontaneous symmetry breaking of the Ni coordination environment after Li extraction under the π-type interaction, which enhances the intrinsic competition between anion and cation oxidation, keeping π* state (from O 2 p splitting) below the metal band to avoid over-oxidation.

However, how to design the non-fullerene acceptor (NFA) with small ∆ E ST and high performance is challenging. Aiming to address this issue, YDF , YTF , and YTF-H were synthesized. Among them, a device based on YDF with partially spatially separated highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) exhibits a much higher power conversion efficiency (PCE) of 20.04%, which is one of the most efficient efficiencies for binary systems. For YTF and YTF-H , their completely spatially separated HOMO and LUMO indeed lead to a much reduced ∆ E ST caused by the low-lying S 1 state, together with excellent charge mobility and light absorption, required for higher performance OPV. But their low S 1 state causes several non-radiative recombinations due to strong S 1 -S 0 coupling (PCE < 1.5%).

Here, based on metal chelation therapy, we propose a strategy of artificially mimicking EMT, integrating ferroptosis and immunotherapy to inhibit tumor growth and metastasis. The prepared ethylene diamine tetraacetic acid-magnesium (EDTA-Mg), on the one hand, chelates Ca 2+ on the surface of tumor cells to form EDTA-Ca, causing the dissociation of tumor cells. Meanwhile, E-cadherin is downregulated, while Vimentin and matrix metalloproteinase 2 (MMP-2) are upregulated, indicating the occurrence of EMT. On the other hand, after EDTA-Ca is endocytosed by tumor cells, it deprives Fe in the lysosomes to form EDTA-Fe, which induces ferroptosis through a Fenton reaction.

The narrow emission bands and energy-transfer processes can be tailored to respond to external stimuli, such as temperature changes and magnetic fields. The application of magnetic fields lifts the Zeeman degeneracy, creating electronic spin polarization, and giving rise to magneto-optical phenomena. Magnetic circularly polarized luminescence (MCPL) is a magneto-optical technique in which the differential emission of left and right circularly polarized light is induced by a magnetic field oriented parallel or antiparallel to the light propagation axis. In the context of lanthanide(III) materials, this technique has only been explored in a few studies as a characterization tool.

Most SABRE experiments have historically been performed in methanol, a relatively toxic and difficult-to-remove solvent. Here we demonstrate the use of a 80/20 acetone/water (A/W) solvent system (Ace-SABRE) to provide hyperpolarized [1– 13 C]pyruvate with up to 17% polarization, then implement a solvent processing protocol to achieve injectable solutions retaining 74% of the initial polarization, and lastly we demonstrate HP in vivo spectroscopy and imaging using the Ace-SABRE platform to showcase metabolic tracking in a hepatocellular carcinoma (HCC) tumor as well as HP-MRI, both in direct comparison to dissolution dynamic nuclear polarization (d-DNP) experiments.

  @article{ , abstract = {Proton-conducting materials play a key role in various fields, and their proton conduction is profoundly restricted by the proton dissociation process. This process has two components: dissociation from acidic groups (e.g., −SO 3 H) and dissociation from intermediate species (e.g., H 3 O + , C─F···H + ). Extensive research has concentrated on the former, utilizing acidic groups with minimal proton dissociation energy or low pKa values, while the latter's substantial effects have been largely overlooked. In reality, proton-accepting atoms within intermediates, such as oxygen and nitrogen, typically produce a higher electron cloud density compared to those in acidic groups. This results in a pronounced electrostatic binding effect on mobile protons, as well as high dissociation energies. Thus, diminishing the dissociation energy associated with intermediates is paramount in the development of high-performance proton conductors. Herein, we construct one covalent organic framework-based proton conductor, achieving superprotonic conduction over a wide humidity range by decreasing the dissociation energy of protons from intermediates. The success of this approach can be attributed to two key factors: the crowded guest molecules within the framework that mitigate proton hydration, and the concurrent establishment of C─H···H + interactions. These combined effects significantly reduce the electrostatic attraction exerted on mobile protons, thereby enhancing proton conduction.}, archive = {J_ANGEW}, author = {Kun Zhang and Lei Wu and Ke Gong and Shuyang Bian and Yanting Zhang and Huayu Gu and Dongshuang Wu and Linfeng Hu and Huiyuan Liu and Yusong Wang}, doi = {10.1002/anie.202421444}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {35}, pages = {e202421444}, shortjournal = {Angew.

  @article{ , abstract = {Iron is in an essential micronutrient in living systems. However, it is also potentially toxic and so the concentration of chelatable iron within cells is tightly regulated to prevent catalytic formation of harmful reactive oxygen species (ROS). Ferritins play a key role in iron homeostasis by storing excess iron as an insoluble ferric mineral within the protein. When bacterial cells become iron deficient, this store may be accessed by reduction/solubilisation of the iron. Bacterioferritins utilise heme, bound at an inter-subunit site, to support electron transfer to the stored mineral. Electrons for heme reduction are shuttled from NADPH via Bfd, a [2Fe–2S] cluster-containing ferredoxin. This raises the paradox that the synthesis of an iron-dependent protein co-factor is required under conditions of iron-deficiency so that stored iron can be utilised. Here, we show that exposure of Bfd to ROS suppresses the capacity of the protein to stimulate iron release from bacterioferritin. We propose that reliance of iron release on Bfd evolved to ensure that chelatable iron levels do not increase under oxidative stress conditions. Thus, the Bfd iron–sulfur cluster functions as a “biological fuse” in providing a fail-safe that immediately halts iron release once ROS accumulate to damaging concentrations.}, archive = {J_ANGEW}, author = {Justin M.

Notably, five-membered rings induce stronger d - p coupling compared to their six-membered counterparts, leading to a higher Fe valence state. This electronic modulation optimizes the adsorption strength of key CO 2 RR intermediates (COOH* and CO*), enhancing catalytic performance for CO production. Extensive experimental studies corroborate these theoretical findings.

  @article{ , abstract = {Covalent organic frameworks (COFs) have shown promise as photocatalysts for chemical transformations. However, their dense micropores and poor pore connectivity hinder mass transport and charge separation/transfer, limiting their efficiency. Herein, we develop a one-step self-sacrificing template strategy to synthesize three-dimensional ordered macroporous COFs (3DOM-COFs). This approach uniquely integrates in situ Tp–Tta COF crystallization with synchronized degradation of polystyrene templates under solvothermal conditions. This method introduces unreported kinetic match between template decomposition and framework growth. Such a confined growth mechanism leads to structurally robust and highly ordered macroporosity without post-processing. 3DOM architecture enables uniform dispersion of fine ZnCdS nanoparticles for the generation a 3DOM-COF based S-scheme heterojunction, which exhibits remarkable performance in the oxidation of benzylamine (BA) for simultaneous N-benzylbenzaldimine production with 99% selectivity at a rate of 15.1 mmol g −1 h −1 and H 2 generation with a rate of 17.8 mmol g −1 h −1 . The 3DOM architecture confers 50-fold faster mass transport than bulk COFs, while the heterojunction facilitates directional charge separation and interface charge transfer. Density functional theory calculations confirm that the heterojunction optimizes reaction thermodynamics by lowering the potential energy barriers of BA activation.

  @article{ , abstract = {Fe–N–C catalyst is the most promising non-noble metal oxygen reduction catalyst for proton-exchange membrane fuel cells (PEMFCs); however, their practical applications are still limited by unsatisfactory long-term stability. This is because the N atoms of the active FeN 4 moiety are easy to protonate, leading to the leaching of Fe atoms, and the H 2 O 2 generated during oxygen reduction reaction (ORR) process triggers the Fenton reaction, further accelerating the dissolution of Fe. To address these critical stability challenge, we developed a general strategy to transform FeN 4 single-atom sites to Fe 2 N 6 dual-atom sites in Fe–N–C catalysts with various carbon substrates. This is achieved by treating the presynthesized Fe–N–C catalysts in a H 2 /Ar atmosphere to break the C─N bonds near the FeN 4 sites while introducing Fe and N precursors to form the Fe 2 N 6 sites. Our theoretical calculations and experimental results demonstrate that the newly formed Fe 2 N 6 sites are structurally more stable in acidic ORR and produce negligible H 2 O 2 (<1%). Therefore, the transformed Fe–N–C catalyst exhibits an extremely low Fe demetalation ratio (0.61 at%) in 0.1 M HClO 4 after 80k cycling. More surprisingly, the transformed Fe–N–C catalyst can effectively decompose H 2 O 2 with a high decomposition rate of 15.7 mmol min −1 , approaching that of the state-of-the art Pt/C catalyst (17 mmol min −1 ).

Here, we demonstrate the first copper-catalyzed asymmetric C─O bond cross-coupling of allylamines and CO 2 in a radical strategy. The key innovation resides in the rational and strategic conversion of C 2 -symmetric oxazoline ligands to their C 1 -symmetric counterparts, which induces additional C─N axial chirality after coordination with copper.

While the majority of current research focuses on cyclic aging, the impact of calendar aging on zinc anodes has received far less attention.

Notably, intrinsic corrosion rates alone do not predict degradation severity; for instance, triflate anion shows low corrosion but induces highly porous deposits and rapid aging. To address this, we propose a comprehensive electrochemical descriptor to quantify deposition morphology beyond traditional morphological characterization. Moreover, we introduce an acetatization strategy that tailors Zn 2+ solvation and promotes dense plating, effectively suppressing side reactions and “dead” zinc formation. This approach effectively curbs calendar degradation, yielding nearly a 49-fold improvement in capacity retention.

By correlating its transport with proteinuria and urinary kidney injury molecule-1 (KIM-1), endogenous biomarkers of glomerular leakage and proximal tubular injury, respectively, we found that glomerular leakage, as indicated by a >50-fold increase in proteinuria, did not enhance its blood clearance.

Supramolecular polymers can offer intriguing properties for the same applications, such as stimuli responsiveness and self-healing owing to their dynamic intermolecular interactions. However, merging the two has remained a formidable challenge, due to the nonplanar geometry of common TADF chromophores. Herein, we overcome this challenge by utilizing a less distorted multiple resonance TADF (MR-TADF) chromophore connected to a polymerization inducing building block. The obtained supramolecular synthon is capable of assembling in aliphatic solvents due to combined interchromophore interactions and hydrogen bonding. Within the supramolecular ensemble the long-lived photoluminescence properties of the chromophore are maintained. Further modification of the photoluminescence properties could be achieved by using different supramolecular modulators in a social self-sorting approach, allowing fine-tuning of the photoluminescence lifetime and bandwidth. Notably, the extent of intermolecular interactions can switch these assemblies from kinetically to thermodynamically controlled regimes. Finally, we employ this co-assembly strategy to move from organic to aqueous media highlighting the potential toward biological applications.}, archive = {J_ANGEW}, author = {Nils Bäumer and Peiqi Hu and Miku Naruse and Soichiro Ogi and Zachary M.

  @article{ , abstract = {Micro/nanoreactors with hollow structures have traditionally focused on the design of the internal catalytic microenvironment, while precise engineering of their external surfaces at a nanoscale level is particularly rare. Here, we develop a unique approach to elaborately engineer the surface of zeolitic imidazolate frameworks (ZIF-8)-based hollow microreactor with fluff-like nanostructures that serve as an external catalytic platform. This involves the anchoring of high-density micellar brushes onto the epidermis of ZIF-8 via surface-initiated living crystallization-driven self-assembly, followed by the rapid capture of multiple species to fabricate the catalytic nanobrushes. Such a nanoscale fluff-like surface in combination with an internal cavity that encapsulates other functional components enables specific spatial isolation of various catalysts. The resultant microreactor with external PW 12 nanobrushes for esterification and internal Pt─Ni alloys for hydrogenation reveals prominent activity toward a tandem conversion of p -nitrobenzoic acid into benzocaine with a high selectivity of 95.4%. Remarkably, the microreactor decorated with PW 12 nanobrushes can greatly prompt the catalytic efficiency of esterification with the inhibited competition from the hydrogenation reaction.

The constructed MSP-IPL possesses high electrochemical stability, superior ion-transfer ability, and good air stability. Due to its high film formation uniformity and mechanical tenacity, the MSP-IPL can effectively avoid nonuniform Li deposition caused by the tip effect, thus inhibiting Li dendrite proliferation. The uniformly distributed Ti-POMs in polymer skeleton can efficiently bind with PF 6 − anions, thus increasing Li + transference number and promoting homogeneous Li + distribution. The reprocessability and self-healing ability endowed by dynamic coordination bonds enable the MSP-IPL to accommodate electrode volume changes and maintain good interface contact. Consequently, high-loading Li||LiFePO 4 and Li||LiNi 0.8 Co 0.1 Mn 0.1 O 2 batteries based on MSP-IPL-coated Li anodes demonstrate impressive cyclability and extraordinary rate capability.

  @article{ , abstract = {Constructing heterogeneous halogen-free catalysts featuring efficiently activated CO 2 and epoxides for the synthesis of cyclic carbonates via an atom-economical route is significant but remains a big challenge. In this work, we develop an atmosphere-assisted strategy for preparing mesoporous CeO 2 nanorods with tunable oxygen vacancy cluster concentrations, which boosts the performance of CO 2 cycloaddition. Pair distribution function (PDF) analysis elucidates that oxygen vacancy clusters regulate the dynamic equilibrium of the multiscale structure of CeO 2 via a synergistic “compression-expansion” mechanism. Furthermore, the high concentrations of oxygen vacancy clusters form abundant frustrated Lewis pairs (FLP) sites, which remarkably promote the adsorption and activation of CO 2 with epoxides. Thus, the performance of CO 2 cycloaddition was substantially intensified. A 95% yield of cyclic carbonate was obtained when the reaction was conducted with RNR-CeO 2 -H 2 at 110 °C.

  @article{ , abstract = {The selective upcycling of polystyrene (PS) waste into value-added aromatics has emerged as a compelling strategy toward sustainable plastic valorization, drawing significant scientific and industrial interest. While most existing methods involved oxidative C─C bond cleavage predominantly yield benzoic acid, the direct conversion of waste PS into phenolic compounds remains largely unexplored. Herein, we report the first example of photocatalytic upcycling of PS into phenol derivatives with high chemoselectivity. This economical method proceeds under ambient conditions (1 atm air and room temperature) using an inexpensive organic photocatalyst via photooxidation-induced Hock rearrangement in a single step. The use of strong acid effectively suppresses the formation of benzoic acid, playing a critical role in high selectivity. Experimental and density functional theory (DFT) calculations revealed that the cis configuration of neighboring phenyl rings in PS raises the barrier for hydrogen atom transfer (HAT) from the benzylic C─H bond, thereby contributing to the low polymer conversion. Furthermore, the novel divergent upcycling of PS to hydroquinone derivatives was achieved by a photo-electro tandem strategy.

The silicon (Si)─oxygen (O) bond energy of siloxane is larger than that of carbon (C)─O of C-siloxane (replacing Si atoms in siloxane with C atoms) because the atomic radius of Si is larger than that of C, and the Pauli exclusion of Si is smaller than that of C.

Herein, we propose a concept of decoupling the activity-selectivity trade-off in the photothermal catalytic reverse water-gas shift (RWGS) reaction by hydrogen spillover-assisted dual-site synergy. This concept is demonstrated through a hybrid catalyst constructed by immobilizing abundant Ru single sites and trace Ru clusters onto high-efficiency photothermal support of N-doped hierarchical carbon nanocages (hNCNC). Theoretical calculations reveal that the Ru─N 4 sites are highly active and selective for the RWGS reaction, contingent on the efficient migration of dissociated *H species to adjacent C atoms of Ru. Importantly, we experimentally confirm that Ru single sites dominate CO 2 hydrogenation to CO, whereas Ru clusters facilitate H₂ activation and supply hydrogen species to adjacent single sites via spillover over hNCNC. Leveraging this synergistic interaction, the hybrid catalyst achieves an exceptional CO production rate of 3.1 mol·g Ru −1 ·h −1 and selectivity over 98%. This mechanism shows universal applicability as demonstrated by the effective promotion of CO 2 hydrogenation of Ru single sites by other typical hydrogen-spillover-active metal clusters, e.g., Pt and Pd clusters.

In this article, we introduce a novel concept for catalytic 1,3-DCA that enables remarkable productivity for both endo (TON up to 4000) and the more challenging exo products (TON up to 1500). This approach, making use of modular polyfunctional Lewis acid/azolium-aryloxide catalysts, allows for precise control over endo - and exo -diastereoselectivity. The switch from endo - to exo -selectivity is accomplished by modifying the metal center, the azolium moiety, and steric factors. As detailed DFT studies reveal, both the endo - and exo -selective catalyst systems exhibit an almost perfect spatial alignment of their key functional sites, allowing for a unique interplay of Brønsted acids and bases, Lewis acids, and hydrogen bonding.

To address this issue, we develop a universal strategy to finely optimize the functionality of perylene-diimide-type CIL (PDINN) by incorporating polyfluorine-substituted copper phthalocyanine (CuPc) derivative to form a hybrid CIL. It is found that the hydrogen bonding and π–π interaction between PDINN and CuPc can address the solvent processability issue of CuPc used as CIL. The incorporation of CuPc in the PDINN layer leads to better film morphology, increased conductivity, and reduced cathode work function, enabling greater CIL thickness tolerance and significantly improved photovoltaic performance of OSCs. Notably, the PM6:D18:L8-BO-based device using PDINN:F16CuPc as hybrid CIL yields a remarkable power conversion efficiency (PCE) of 20.17%, which is a significant improvement with regard to the PCE of 19.29% for the control device based on PDINN CIL. Particularly, this strategy demonstrates a universality in multiple photoactive layers and various perylene-diimide-based CILs, offering an effective approach to developing highly efficient OSCs.}, archive = {J_ANGEW}, author = {Hang Yang and Wenjing Zhang and Xiaoxiao Li and Ya Yuan and Yue Wu and Xiaoying Xiong and Chaohua Cui and Yongfang Li}, doi = {10.1002/anie.202507294}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {34}, pages = {e202507294}, shortjournal = {Angew.

  @article{ , abstract = {Plastic disposal has become a serious environmental and social problem. Mechanical recycling of waste plastics is the most widely adopted strategy to address this issue, but if used to recycle mixed plastics, it usually requires the addition of amphiphilic block copolymers. Polyolefins account for almost half of all synthetic plastics, making them ubiquitous in the plastic waste stream. Within this perspective, polyolefin-based multiblock copolymers are highly desirable, but they are difficult to access using traditional strategies. In this contribution, a cascade ring-opening metathesis polymerization (ROMP) and reversible addition-fragmentation chain transfer (RAFT) polymerization strategy was developed to prepare various polyolefin-based multiblock copolymers with tunable polar segments and microstructures. Using this strategy, tunable amounts of the trithiocarbonate RAFT agents were installed in the polyolefin main chain via ROMP. Subsequent chain extension of various polar vinyl monomers via controlled RAFT polymerization formed various polyolefin-based multiblock copolymers with high molecular weight and good physical properties. These multiblock copolymers were used to compatibilize and upcycle mixtures of high-density polyethylene/polymethyl methacrylate (HDPE/PMMA) and high-density polyethylene/polyethylene terephthalate (HDPE/PET).}, archive = {J_ANGEW}, author = {Min Chen and Guifu Si and Wen-Jian Zhang and Changle Chen}, doi = {10.1002/anie.202507257}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {34}, pages = {e202507257}, shortjournal = {Angew.

  @article{ , abstract = {Photoredox chemistry has seen a dramatic rise in popularity in recent years, but mechanistic understanding has persistently lagged behind reaction development itself. This is particularly true for the emerging area of consecutive photoinduced electron transfer (conPET), which has attracted both great interest due to its ability to activate inert substrates selectively and under mild conditions and continuing controversy over its mechanistic feasibility. We describe herein the isolation of the key radical intermediate state of an acridinium-based conPET catalyst and detailed investigations of its photochemistry by a suite of (photo)reactivity, photoluminescence and transient absorption techniques, supported by computational studies. We observe strong wavelength and solvent dependencies in the reactivity profile, which correlate well with observations of a long-lived, fluorescent excited state that would be compatible with diffusion-limited reactivity. However, photoluminescence and transient absorption spectroscopies suggest that, counter-intuitively, this state does not actually participate in reactivity. Instead, changes occur far faster than the diffusion limit, which provides strong, direct evidence for preassembly of the photocatalyst and substrate prior to photoexcitation. Further inspection also indicates parallel formation of solvated electrons, likely providing the major pathway under previously reported synthetic conditions, suggesting that otherwise competing rationales for conPET can in fact operate simultaneously.}, archive = {J_ANGEW}, author = {Samuel J.

The dependence of recovery time on light wavelength is rationalized qualitatively via highly correlated quantum-chemical calculations of the absorption spectra of S8 chains.

  @article{ , abstract = {Radical-mediated chlorination of ethane presents a low-carbon alternative for polyvinyl chloride (PVC) synthesis, yet selectivity toward 1,2-dichloroethane remains challenged by uncontrolled over-chlorination. Lanthanum oxychloride (LaOCl) has emerged as a promising catalyst, but its structural dynamics under Cl 2 -rich conditions and the origin of selectivity loss remain elusive. Here, we integrate advanced spectroscopic techniques with theoretical calculations to address this knowledge gap. Our findings unveil a sequential LaOCl → LaCl 3 transformation that dictates product distribution shifting from 1,2-dichloroethane to trichloroethane. Mechanistic insights reveal that surface hydroxyl groups, generated during catalyst chlorination, promote bidentate adsorption of 1,2-dichloroethane via hydrogen-bond networks, thereby activating C─Cl over-chlorination. Additionally, by employing Al 2 O 3 -supported LaCl 3 model catalysts, the size-dependent chlorophilicity of the LaCl 3 species is demonstrated. The bonding of interfacial oxygen with monolayer-dispersed LaCl 3 species generates empty 4f-states above the Fermi level, creating strong Lewis acid sites that stabilize Cl radicals and selectively convert chloroethane to 1,2-dichloroethane. In contrast, aggregated nanoparticles are inactive due to their inability to stabilize chlorine radical. Our findings establish important structure sensitivity in lanthanum-catalyzed chlorination and provide guiding principles for catalyst design, highlighting the importance of stabilizing metastable LaOCl x species and modulating surface hydroxyl chemistry to overcome selectivity limitations.}, archive = {J_ANGEW}, author = {Yuting Li and Haifeng Qi and Zihan Zhu and Xia Wu and Nicholas F.

The r -Zn–MOF74–NT exhibited a space-time yield of 1035.8 g BHET g cat −1 h −1 at 190 °C. Importantly, this is an order of magnitude higher than that reported for similar MOF-based catalysts.

In situ characterizations and theoretical calculations confirm that the electron-delocalized Cu 2+ triggers a high spin-state of O in Fe Td 2+ ─O─Fe Oh 3+ , thus creating a spin channel for the spontaneous intermolecular electron transfer of PMS from the Fe Oh 3+ adsorption site to the Fe Td 2+ adsorption site through Fe Td 2+ ─O─Fe Oh 3+ .

  @article{ , abstract = {A practical strategy in synthetic organic chemistry for shutting down temporarily the nucleophilicity of thiols is to exploit their redox properties by converting them into disulfides. The stability of such a thiol protection in reductive medium can be sensitive to microenvironmental changes, including chemical modifications occurring nearby. Although difficult to achieve, large shifts in disulfide stability might provide a practical mean for bringing selectivity in a reacting system comprising multiple thiol functionalities. Here we report that the stability of a cyclic disulfide increases dramatically upon acylation of an amino group placed in the vicinity of the S─S bond. The gain in stability is so pronounced that the amide bond formation acts as a redox lock.

  @article{ , abstract = {Traditional responsive fluorescent probes are predominantly restricted to qualitative biomarker detection, incapable of delivering real-time quantitative analysis or spatial mapping of protease activity in vivo, which is essential for elucidating disease progression. To overcome this, a ratiometric second near-infrared region (NIR-II) fluorescent (FL) probe (DCNP@IR-806) was developed by conjugating caspase-3-specific peptide substrates and sensitizer molecules (IR-806) to lanthanide-doped down-conversion nanoparticles (DCNP). DCNP@IR-806 achieves single-channel emission at 1550 nm under dual excitation, facilitating self-calibrated quantification and real-time monitoring of activated caspase-3 in vivo. Radiotherapy induces tumor cell apoptosis, thereby activating caspase-3, which subsequently triggers a ratiometric NIR-II FL signal change of DCNP@IR-806. The ratiometric signal demonstrates a linear correlation with caspase-3 concentration, achieving a detection limit of 9.96 U mL −1 . Then, an early efficacy assessment system capable of predicting radiotherapy outcomes within 12 h post-treatment was constructed, markedly expediting evaluation compared to traditional methods that require weeks. This rapid, precise, and user-friendly assessment facilitates timely optimization of therapeutic regimens to enhance efficacy while minimizing side effects.

Given the significance of fluorine-containing molecules in pharmaceutical sciences, a regiodivergent [3+2] cycloaddition of gem -difluorocyclopropyl urea to olefins and [1.1.0]-bicyclobutanes was developed by employing cationic iridium complexes as photocatalysts under visible-light irradiation. By properly selecting a counteranion of the photocatalyst and tuning the reaction conditions, each regioisomeric cyclic hydrocarbon with a defined gem -difluoromethylene disposition was directly assembled with high selectivity. Mechanistic elucidation revealed the critical relevance of the basicity of the photocatalyst counteranion to the regiochemical outcome. The reaction diverges depending on the intervention of deprotonation of the initially generated urea radical cation by the pairing anion to form the corresponding neutral radical; this not only governs the regioselective ring opening of the cyclopropane moiety but also modulates the relative reactivity of the two resulting terminal carbon radicals, thereby dictating the dominant pathway.}, archive = {J_ANGEW}, author = {Tobias E.

Using scanning tunneling microscopy, noncontact atomic force microscopy, and density functional theory calculations, the atomic structures and electronic properties of O-doped GNRs are determined, demonstrating that both GNRs are direct bandgap semiconductors with different sensitivities to oxygen dopants.

This study investigated the enhancement of electron transfer and transport rates during MgH 2 de/hydrogenation by introducing a single-atom catalyst composed of Ru single atoms on a Nb 2 O 5 substrate. The Ru 0.028 @Nb 2 O 5 single-atom catalyst reduced the peak dehydrogenation temperature of MgH 2 from 429°C to 214 °C, and the activation energies for de/hydrogenation were reduced by 53.7% and 83.9%, respectively. Furthermore, the 15 wt.%-Ru 0.028 @Nb 2 O 5 -MgH 2 composite maintained 97.4% capacity after 100 cycles. Based on excellent performance and theoretical calculations, it was demonstrated that the electronic structure modulation of Nb 2 O 5 by Ru single atoms enhanced the electron transfer and transport capacities, and the synergistic effects of single-atom Ru (dominant role), multivalent Nb, and oxygen vacancies resulted in remarkable catalytic activity.

  @article{ , abstract = {The selective activation of inert C─H bonds in methanol under mild conditions to synthesize high-value C 2 products remains a formidable challenge, primarily due to the competing high reactivity of O─H bonds. Herein, we pioneer a chlorine radical-mediated strategy to redirect the photocatalytic reaction pathway for methanol conversion toward ethylene glycol (EG). Efficient C─H bond activation is achieved by constructing a Z-scheme heterojunction photocatalyst (ZnIn 2 S 4 /TiO 2 -Cl) composed of chlorinated TiO 2 (TiO 2 -Cl) and ZnIn 2 S 4 with efficient charge separation. Photogenerated holes in this system preferentially oxidize surface-adsorbed Cl − to chlorine radicals (Cl•). These radicals drive a thermodynamically favorable hydrogen atom transfer via hydrogen abstraction, cleaving the C─H bond of methanol to form hydroxymethyl radicals (•CH 2 OH). Subsequent C─C coupling of •CH 2 OH intermediates, synergistically combined with a self-sustaining Cl − /Cl• cycle, produces EG with exceptional selectivity (96.7%) and yield (21.6 mmol g −1 ) while suppressing overoxidation. In contrast, nonchlorinated catalysts predominantly utilize photogenerated holes for O─H bond cleavage under identical conditions, yielding only C 1 products (HCHO, HCOOH).

Specifically, a metastable Cu single atom (Cu 1 ) precursor as structural seed reconstructs to an exceptional acetylene semihydrogenation catalyst under moderate operational conditions, which undergoes a copper active site reconfiguration employing reactants themselves as inducing medium. This self-evolving reconfiguration creates cooperative Cu 1 and Cu nanocluster (Cu n ) ensemble sites with a dynamic active configuration, which is unavailable by conventional thermal reduction methodology, for adaptive multisubstrate H 2 and acetylene activation.

Contrary to unreactive linear species, trigonal planar variants promote β-H elimination, hydrogenolysis, and catalytic hydrogenation of unactivated alkenes at mild temperatures and H 2 pressure. The rare isolation of a naphthyridine- bis (carbene)CuH monomer further affirms two predominant competing pathways for H 2 cleavage of metal–ligand cooperativity at Cu(I)-alkyl or internal electrophilic substitution at Cu(I)-OH. Employing either isolated or in situ generated Cu(I)-OH complex, via protonolysis of alkyl precatalyst by adventitious water, significantly accelerated catalysis compared to that operating primarily by the metal–ligand cooperativity pathway.

However, the formation of a chiral polymer from achiral monomers continues to be a mystery. We exploited the ability of achiral molecules to rarely crystallize in chiral space groups to design achiral monomers for topochemical polymerization to obtain chiral polymers. One such achiral monomer synthesized, viz. a tripeptide monomer containing alkene and azide at its termini, crystallized in a chiral space group, forming a conglomerate as revealed by single-crystal X-ray diffraction. Upon heating at a temperature above 70 °C, each enantiomorphic crystal underwent a regiospecific and stereospecific topochemical ene-azide cycloaddition reaction in a single-crystal-to-single-crystal fashion to give a triazoline-linked homochiral helical polymer. We characterized several homochiral polymer crystals at atomic resolution either by SCXRD or by 3D electron diffraction.}, archive = {J_ANGEW}, author = {Divina Xavier and Sourav Pathak and Christian R.

  @article{ , abstract = {Solid-phase peptide synthesis has become an indispensable technique for the routine preparation of linear peptides of up to approximately 40 amino acids in length.

Moreover, many of the deletion impurities that can form are often chromatographically inseparable from the target sequence, which diminishes final product purity. The use of backbone N -protecting groups can ameliorate this synthetic inefficiency by increasing peptide chain solubility and suppressing aggregation. Backbone protection is also useful for promoting peptide macrocyclization, suppressing common side reactions in peptide chemistry, and improving solution-phase handling. Commercially available precursors containing benzyl-based groups and pseudoprolines have found widespread use, in academic laboratories and industry. A range of other strategies have also been investigated in a bid to increase the utility of backbone protecting groups and to develop more efficient methods for their introduction and removal.

  @article{ , abstract = {[ n ]Cycloparaphenylene ketone 4 , [ n ]CPP-CO, in which a carbonyl group is inserted into [ n ]CPP framework, with n = 6, 7, 8, and 10, was synthesized by a coupling reaction between a CPP precursor and a ketone unit, followed by reductive aromatization. Single crystal X-ray diffraction analysis and density functional theory (DFT) calculations confirmed their Möbius topology and significant molecular strain as characterized by the deviations in bond angles at the carbonyl carbon. The strain was also evidenced by size-dependent 20–50 cm −1 shifts in the carbonyl IR stretching bands. The CPP units in 4 significantly alter the electronic properties, particularly the relative orbital energies. Due to the elevation of the energy level of the occupied π-orbitals by CPP units, the highest occupied molecular orbital (HOMO) in 4 is the conjugated π-system, in contrast to benzophenone, where the HOMO is the non-bonding n-orbital. Consequently, the lowest excited state of 4 is the singlet state (S 1 ) with π–π* character rather than the conventional n–π* triplet (T 1 ) state. Furthermore, intersystem crossing from the S 1 state to the T 1 state, which is a characteristic process for typical aromatic ketones, does not occur efficiently. As a result, 4 exhibits unique photophysical properties opposite to those of typical aromatic ketones, such as fluorescing but not phosphorescing. Furthermore, the S 1 state of 4 was quenched by molecular oxygen, most likely by the energy exchange mechanism. Optical and electrochemical properties showed a clear dependence on ring size, with smaller rings exhibiting greater strain, lower oxidation potentials, and red-shifted absorption and emission. These findings highlight the unique interplay between molecular topology, strain, and photophysics in CPP-based ketones and provide a foundation for designing novel π-conjugated materials with tailored excited-state properties.}, archive = {J_ANGEW}, author = {Eiichi Kayahara and Ryota Okahara and Amiri Shibata and Manabu Abe and Shigeru Yamago}, doi = {10.1002/anie.202509754}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {33}, pages = {e202509754}, shortjournal = {Angew.

  @article{ , abstract = {Platinum (Pt) has been widely employed in photocatalytic H 2 production. However, the influence of CO on proton reduction to H 2 over Pt active species remains unknown. Herein, using Pt/Nb 2 O 5 as a model catalyst, the role of Pt active species in CO-sensitive photocatalytic H 2 evolution is evaluated. Our results reveal that Pt 4+ species exhibits superior activity in H 2 production when the CO-to-Pt molar ratio is low ( n CO / n Pt ≤ 1.3), but their photocatalytic performance is suppressed at a high n CO / n Pt ratio (>1000). By contrast, increasing the loading amount of Pt suppresses Pt 4+ species formation and the low valence state Pt species show inferior activity for H 2 production, which is almost unaffected by the n CO / n Pt ratio. The CO-TPD results, in situ FTIR spectra, and DFT calculations indicate that the role of adsorbed CO molecules is to impede the interaction between H 2 O and Pt 4+ species and prevent the generation of *H species for H 2 production. Significantly improving the H 2 production rate by purging with argon suggests the importance of inhibiting the adsorption of CO on Pt 4+ species.

Herein, we report a new series of overcrowded-ethylene (OCE) decorated (diaza)phosphinines. Combining with the main-group element and nonplanar OCE structures, new P-molecules showed the tunable folded(F)/twisted(T)-conformations and physical properties via the distinct P-hyperconjugation of the P─C and P─N bonds. Such hyperconjugation-induced tunability is different from the classical OCEs where p-π/π-π conjugation effects are the dominating factors controlling the structures and properties. Furthermore, bromination of NP-oxide derivative induced an unexpected chemochromic T→F isomerization, highlighting the dynamic conformation character. Leveraging on the different structures, CP and NP derivatives further enabled the formations of radical cations and anions having different spin characters on the P-centers. As the new example of P-Thiele's hydrocarbon family, combining the NP structure with the overcrowded anthraquinodimethane structure yielded a light-responsive open-shell NP-anthraquinodimethane diradicaloid with a triplet ground state, which was influenced by the PN hyperconjugation effect in F-conformation and the aromaticity gain in T-conformation. Overall, our new strategy, namely the hyperconjugation-regulated tunability, paves the way toward complex organic materials with tunable the structures and physical properties.}, archive = {J_ANGEW}, author = {Zhaoxin Liu and Zi Yang and Chao Li and Huanchao Gu and Xinyu Li and Yi Ren}, doi = {10.1002/anie.202508880}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {33}, pages = {e202508880}, shortjournal = {Angew.

The development of mid-far infrared (MFIR) birefringent crystals has long been shackled by the incompatibility between giant optical anisotropy and ultrabroad transparency in conventional chalcogenides. Here, we break this shackle via heterotriple-chalcogenide engineering in the first thiotellurite birefringent family, BaTeQ 3 (Q = S, Se), featuring isolated [TeQ 3 ] 2 ⁻ motifs. BaTeS 3 achieves a large experimental birefringence (Δ n = 0.193@550 nm, 15× commercial MgF 2 ). More strikingly, the assembly of three distinct Group VIA chalcogens (S, Se, Te) creates the first heterotriple-chalcogenide motif—[TeSeS 2 ] 2 ⁻ in BaTeSeS 2 , delivering giant Δ n = 0.55@550 nm—a 284% increase from BaTeS 3 and surpassing all commercial benchmarks. BaTeSeS 2 concurrently exhibit ultrabroad transparency (0.5–25 µm), overcoming the classical trade-off between anisotropy and transparency.

  @article{ , abstract = {High-voltage and fast-charging lithium metal batteries (LMBs) are crucial for overcoming electric vehicle range and charging limitations. However, conventional carbonate electrolytes face intrinsic limitations in simultaneously achieving compatibility with high-voltage cathodes and lithium metal anodes. These limitations arise from sluggish Li + transport kinetics and parasitic side reactions, both largely driven by excessive Li + solvation energy inherent to carbonates. To address these challenges, we propose a conformational engineering strategy of fluorinated solvent molecules by developing a 2,2,3,3,4,4-hexafluoropentanedioic·anhydride (HFPA)-derived electrolyte (HFPE). The chair conformation of HFPA synergizes with its high F/C ratio to establish a low-polarity solvation environment, effectively reducing desolvation energy barriers.

How to regulate their charge transfer to enhance radiative emission is an intractable challenge. Here, guided by coordination dynamics, we present a solvent mediation strategy to modulate coordination environments and intramolecular charge transfer of organic cuprous halides to achieve vibrant emissions. Mechanistic studies reveal that the coordinated clusters can efficiently absorb radiation ionization to generate electron-hole pairs and transfer them to ligands for enhanced luminescence. Conversely, ligand-free structures exhibit an absence of organic-ligand-related excited states upon excitation, leading to luminescence quenching.

  @article{ , abstract = {Sensitive detection of viral RNA is critical for accurate diagnostic testing, particularly during outbreaks of emerging infectious diseases. Rolling circle amplification (RCA) is a powerful isothermal amplification strategy that can be directly primed by RNA, eliminating the need for reverse transcription. Previous approaches have used 10–23 DNAzymes to cleave viral RNA, generating 3′-ends for hybridization to circular DNA templates (CDTs). However, the resulting RNA fragments often retained secondary or tertiary structures that hindered CDT binding and limited RCA efficiency. To address this challenge, we developed antisense oligonucleotide-assisted RCA (ASO-RCA), a general strategy that uses short upstream antisense oligonucleotides (ASOs) to remodel RNA structure and expose the CDT-binding site. Using five DNAzyme-CDT systems targeting distinct regions of the SARS-CoV-2 genome, we show that ASO inclusion improves CDT hybridization and enhances RCA output—by up to 70-fold. This enhancement was observed using both linear and quasi-exponential RCA formats and remained effective in 50% pooled saliva. When applied to clinical saliva samples, ASO-assisted RCA markedly improved diagnostic performance, achieving 100% sensitivity and up to 97.5%–100% accuracy across multiple systems. These findings establish ASO-DNAzyme-RCA as a simple, robust, and clinically relevant platform for improving nucleic acid detection in structured RNA targets.}, archive = {J_ANGEW}, author = {Amal Mathai and Jimmy Gu and Connor Nurmi and John D.

By comparing p -FPEA 2 PbI 4 and PEA 2 PbI 4 , we demonstrate that larger dipole moments amplify lattice distortion and local symmetry breaking, as confirmed by second-harmonic generation (SHG). This structural asymmetry doubles the Rashba spin-splitting energy, quantified through the circular photogalvanic effect (CPGE) and circularly polarized light excited photoluminescence (CPLEPL).

Elaborating on the molecular mechanisms of acid-induced carbamazepine (CBZ) dissolution, we suggest a molecular simulation case study of “Nernst-Brunner type” drug release to an aqueous solution featuring an interfacial “diffusion” layer. Mimicking pH = 2, we find drastic protonation of the drug crystallite model, followed by the dissolution of both single CBZH + solutes and fragments of the crystal edges. The latter lead to the release of [CBZH n ] n+ aggregates (with n = 2–8) into the solution, thus fueling a dynamic interplay of different solute species. In some analogy to so-called two-step crystal nucleation, we therefore suggest a two-step crystal dissolution mechanism encompassing solute aggregates within a “dense-solutes domain”.

  @article{ , abstract = {Sluggish hole transport kinetics are one of the key limitations of bismuth vanadate (BiVO 4 ) photoanodes in photoelectrochemical (PEC) water splitting, severely impeding the attainment of high solar-to-hydrogen (STH) conversion efficiency. Herein, a copper sulfide (CuS) hole transfer layer (HTL) with photothermal effect is reported to markedly enhance the PEC water splitting via the synergistic action of photothermal effect and hole transfer. This is demonstrated in the BiVO 4 /CuS/NiFeCoO x photoanode, where the CuS layer establishes a transport channel for photogenerated holes, effectively inhibiting charge recombination and trapping. Additionally, the thermal effect induced by localized surface plasmon resonance (LSPR) enhances the water oxidation activity of the surface NiFeCoO x cocatalyst and boosts the charge mobility. The optimized BiVO 4 /CuS/NiFeCoO x photoanode exhibits exceptional performance, achieving a water oxidation photocurrent density of 6.56 mA cm −2 at 1.23 V versus reversible hydrogen electrode (V RHE ) and a STH conversion efficiency of 7.17% when connected in series with Si solar cells. Experimental analyzes and density functional theory (DFT) calculations collectively reveal the pivotal role of CuS HTL in facilitating carrier separation and transport.

  @article{ , abstract = {Triplex DNA, a critical noncanonical nucleic acid structure, plays essential roles in gene regulation, disease pathogenesis, and therapeutic targeting. To unravel how environmental and sequence factors modulate triplex stability, we developed a high-throughput 5D fluorescence resonance energy transfer melting annealing (5DFRETMA) method. No less than 414 sets of buffer conditions were tested. Monotonically negative correlations were observed between thermal stability and pH, as well as between pH stability and temperature. These relationships are sequence dependent: triplexes with higher G•C + Hoogsteen base pair content display a higher sensitivity to pH and temperature variations. Ionic strength exerts dual effects: stabilizing the Hoogsteen hydrogen bonds in A•T base pairs while destabilizing them in G•C + base pairs, resulting in a complex ionic strength dependent stability diagram. Critically, as the G•C + content increases, the relationship between triplex stability and ionic strength shifts progressively from a monotonically positive to negative dependence. We developed predictive models that not only predict thermal stability but also pioneer the prediction of pH stability under variable temperatures and ionic environments.

Lattice selenium (Se) doping is an effective strategy to improve hydrogen evolution reaction (HER) of metal-based electrocatalysts in cathodes, but many fundamental questions concerning the actual role of Se on the active species as well as catalytic kinetics remain to be clarified, especially in those electrocatalytic self-reconstruction systems.

  @article{ , abstract = {Nitrogen/carbonyl (N/C═O) based multi-resonant thermally activated delayed fluorescence (MR-TADF) emitters are attractive due to their bright, narrowband emission and the ease with which they can be synthesized. However, their photophysics typically suffer from slow reverse intersystem crossing (RISC) because of their relatively large singlet-triplet energy gap (Δ E ST ). Thus, the organic light-emitting diodes (OLEDs) with these emitters typically show severe efficiency roll-off. Here, two MR-TADF emitters DiKTaSe and tBuCz-DiKTaSe have been designed and synthesized. The introduction of selenium in the form of an annelated benzoselenophene enhances spin-orbit coupling and increases the RISC rate. The twisted ortho -substituted tert -butylcarbazole moiety in tBuCz-DiKTaSe helps to suppress aggregation-caused quenching of the emission in films. In addition, the large size of the selenium atom and long C─Se bonds induce helical chirality in both DiKTaSe and tBuCz-DiKTaSe . Finally, the OLEDs with DiKTaSe showed maximum external quantum efficiency (EQE max ) of 22.7% while OLEDs with tBuCz-DiKTaSe showed a higher EQE max of 27.8% and less-pronounced efficiency roll-off, with EQE at 100 cd m −2 (EQE 100 )/ EQE at 1000 cd m −2 (EQE 1000 ) of 23.5/12.5%.

The incorporation of three pyrrole rings to the periphery of the bowl endows it with strong electron-rich character, showing three reversible oxidations in cyclic voltammetry (CV), and thus could be progressively oxidized into cationic radical and high-charged species upon gradual addition of the oxidant. Interestingly, the cationic radical was also generated by acids, which could be significantly accelerated by light, whether under an air or inert atmosphere. 3N-HBC exhibits interesting properties that arise from its electron-rich character and the unique curved geometry. 3N-HBC proved to be a superior organic photocatalyst for the conversion of 2-isocyanobiphenyl to phenanthridine derivatives at 1.0 mol% catalytic loading under blue LEDs irradiation.

Consequently, extended durability (4400 h at 5 mA cm −2 and 1 mAh cm −2 ), boosted coulombic efficiency (99.8% for 7500 cycles), and ultralong cycling for 8000 cycles at a high loading of 10 mg cm −2 were maintained.

However, the specific effects of Al distribution on the active Al species have not been thoroughly investigated. Herein, aluminosilicate FER-type zeolites with controllable Al distribution were developed. Al distribution, including the arrangement and location of Al atoms, was characterized using 27 Al MQMAS/MAS and 29 Si MAS NMR spectra. The arrangement of aluminum, particularly the isolated Al and paired Al in as-synthesized samples, influenced the proximity between oxidative and acidic sites in H-type samples. Al locations involved the specific positioning of bifunctional sites and affected the final product. The increased CH 4 conversion at 250–275 °C of FER zeolite with Al preferential population at T4 sites confirmed the higher activity of Al species from T4 sites. Additionally, a higher proportion of Al atoms in 10-ring channels facilitated the tandem conversion of methane to methanol on oxidative sites, followed by methanol to hydrocarbons on acidic sites at 300–375 °C.

To enhance SEI stability, numerous electrolyte additives have been designed to decompose on the anode and form desirable SEI components (e.g., LiF). However, their electrochemical reduction kinetics on the anode surface competes with other electrolyte components, leading to suboptimal interfacial decomposition efficiency and a less stable SEI structure. Here, inspired by bioremediation strategies in petroleum pollution treatment, we introduce a proton acceptor that reacts with fluoroethylene carbonate (FEC), a commercially established additive, to generate an intermediate. Such an intermediate lowers the reduction kinetic barrier, accelerating the formation of LiF and enriching it in the inner layer of the SEI. Compared to the randomly distributed LiF structure, the resulting SEI exhibits better mechanical stability and lithium-ion conduction, effectively accommodating volume changes and mitigating stress concentration caused by local overlithiation. As a result, the electrochemical performance surpasses that of previously reported works.

The manganese salts further accelerated the overall reaction rate (10 times faster reaction rate with the manganese salt than that of the manganese-free conditions).

  @article{ , abstract = {Aromatic aldehydes are pivotal synthetic intermediates with applications in fine chemicals, pharmaceuticals, agrochemicals, and advanced materials. Although the oxidation of methylarenes represents an ideal route to aromatic aldehydes due to the availability of starting materials, existing methods face significant challenges, including reliance on hazardous oxidants, costly catalysts, poor scalability, and limited compatibility with electron-deficient substrates. To address these limitations, we report a practical and scalable electrochemical method for the oxidation of electron-deficient methylarenes to access aromatic aldehydes, eliminating the need for chemical oxidants or homogeneous transition-metal catalysts. This approach operates under industrially viable conditions—high current densities (75 mA cm⁻ 2 ), minimal electrolyte loading (0.05 equiv), and operation in an undivided cell without additives—to produce aromatic acetals, which are readily hydrolyzed to the corresponding aldehydes. The use of minimal electrolyte not only reduces costs and simplifies product isolation but also significantly enhances anodic oxidation selectivity, ensuring high efficiency and practicality. This protocol exhibits a broad substrate scope, compatibility with both batch and continuous flow systems, and exceptional scalability, as demonstrated by successful kilogram-scale synthesis.}, archive = {J_ANGEW}, author = {Chong Huang and Hai-Chao Xu}, doi = {10.1002/anie.202504612}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {33}, pages = {e202504612}, shortjournal = {Angew.

Based on Sand's time formula, this study proposes a novel bidirectional ion kinetic regulator concept. Verified in lithium-sulfur batteries (LSBs), it is demonstrated that regulating the migration of anions and cations simultaneously can effectively promote the realization of dendrite-free batteries. This bidirectional ion kinetic regulator forms octahedral complexes with TFSI − , decreasing TFSI − migration, enhancing Li + desolvation and diffusion, and thus extending the dendrite formation time by over 25 times. Moreover, the attraction of the regulator towards solvent molecules and its improvement on the sulfur reduction kinetics effectively suppress the shuttle effect. Subsequently, the assembled Li||Li (1 mA cm −2 for 2000 h), Li-Cu (99.4% of CE), and Li-S (1000 cycles at 4 C) cells deliver extremely excellent cycling stability.

Although nucleic acids can assemble into programmable nanostructures through base-pairing interactions, their chemical diversity is limited to four nucleobases.

These amphiphiles self-assemble into diverse morphologies, such as spheres, fibers, or sheets, with closely packed, parallel DNA strands on their exterior. This unusual arrangement can give rise to emergent properties absent in simple DNA strands. Here, we show that the precise sequence of single-stranded DNA, independent of double helix base-pairing, can be used to program the self-assembled morphology of DNA amphiphiles.

  @article{ , abstract = {The thermodynamic stability and intrinsic kinetic inertia of CO 2 present a critical challenge for its effective activation in the synthesis of high-value dimethyl carbonate (DMC). In this work, we report the fabrication of novel O-Ce-O vacancy clusters (V O-Ce-O ) incorporated into CeO 2 nano-sheets with a near single-unit-cell thickness to construct atomically adjacent multiple active sites on their surfaces. These active sites significantly enhance the activation of both CO 2 and CH 3 OH. Impressively, the as-prepared CeO 2 with V O-Ce-O catalyst exhibits an excellent DMC yield of 31.2 mmol g −1 , surpassing previously reported Ce-based catalysts under equivalent reaction conditions. Experimental results and theoretical calculations reveal that oxygen vacancy increases the reducibility of lattice oxygen, facilitating CO 2 activation, while cerium vacancies weaken the *CH 3 O adsorption, promoting the coupling reaction between *CH 3 O and *CO 2 to form the intermediate (*CH 3 OC(O) 2 ). Notably, the formation of vacancy clusters reduces the energy barrier for the rate-controlled step (*CH 3 OC(O) 2 dissociation to *CH 3 OCO), thereby boosting the DMC yield.

This unique architecture leverages a significantly increased specific surface area, which facilitates rapid electrode–electrolyte interactions and boosts pseudocapacitive contributions. This integrated structure, featuring optimized coordination environments and interfaces, promotes synergistic multi-anionic (S/Se/O) and cationic (V) redox activity and facilitates efficient charge transfer across the interfaces, overcoming intrinsic limitations of capacity and structural instability often observed in single-phase materials, especially during prolonged cycling. This optimized cathode achieves a record-high reversible capacity of 432 mAh g −1 at 1 A g −1 , surpassing mild-oxidized and over-oxidized VSSe counterparts. Remarkably, it retains 80% capacity after 14 000 cycles at 30 A g −1 under cryogenic conditions of −10 °C, demonstrating unprecedented low-temperature durability. The structure–function relationship of heterojunction is driven by enhanced p–d orbital hybridization and spin polarization effects at the heterointerfaces, contributing to the improved redox activity and kinetics.

Here, a strong-super-cooling electrolyte with a multi-ion coordinated water network (hybrid electrolyte of dilute acid and chaotropic zinc salt) is designed for fast proton transport at low temperatures. The chaotropic zinc salt not only reduces the number of free water but also minimizes the number of strong hydrogen bonds in the electrolyte, thus inhibiting the transition of the water molecules to an ordered arrangement at low temperatures.

Herein, we report a Fe(OH) x modified Pt clusters (∼1.6 nm) catalyst supported on MgAlO x (denoted as MA) derived from PtFeMgAl-layered double hydroxides (PtFeMgAl-LDHs) precursor, which is featured with abundant Pt δ + –(OH) x –Fe 3+ interfacial sites. Impressively, the optimal catalyst Pt-Fe(OH) x /MA exhibits exceptional catalytic performance towards CO-PROX, which can completely remove CO in a H 2 -rich stream with an ultra-wide full CO conversion window (25°C−225 °C) at a rather high space velocity (130 000 mL g cat −1 h −1 ).

A comprehensive investigation based on in situ experimental studies and theoretical calculations reveals that the –OH group at the Pt δ + –(OH) x –Fe 3+ interfacial site is easily bound to the linearly-adsorbed CO at the adjacent Pt δ + site to form carboxylate intermediate, followed by its decomposition to CO 2 .

  @article{ , abstract = {The electrocatalytic oxidative cleavage of the C─C bond is highly effective for converting lignin biomass into high-value-added aromatic chemicals. However, the oxygen evolution reaction (OER) at applied oxidative potential usually competes in the aqueous environment. In this study, we found that OER does not entirely hinder the cleavage process but rather acts as a synergistic catalytic step. By using defect-rich carbon nanotubes as the electrocatalyst and combining experimental and theoretical analysis, we found that the reactive oxygen species (O 2 − ) formed before *O 2 desorption serve as the key oxygen source. These species could interact with the enolate intermediate of lignin, which facilitates the in situ production of aromatic compounds.

Comprehensive analyses of physical characterization and catalytic performance confirm the effectiveness of the SWP strategy.

Critically, such a membrane exhibits ultralow voltage decay rate (0.04 mV h −1 over 904 h at 200 °C) and high PA retention ability, coupled with mechanical robustness exceeding industrial durability thresholds.

This paper presents a versatile redox-neutral method for the alkenylation of long-chain alkyl alcohols at unactivated δ-C(sp 3 )-H sites, enabling the construction of alkenols through electrophotochemical (EPC) cerium (Ce) catalysis with free alcohols. The method demonstrates excellent substrate compatibility, facilitating the use of both primary and secondary alcohols and enabling the successful synthesis of quaternary carbon alkenols. Mechanistically, cyclic voltammetry experiments reveal that the oxidative reaction is driven by electrochemical oxidation at the anode under applied potential. Additionally, styrene boronic acid remains unoxidized during the reaction, confirming a radical addition mechanism rather than a radical–radical coupling process.

This dendrimer is well-designed by the direct covalent linkage between the flexible dendritic diphenylamine (DPA) and rigid diradical-featured CR units. The intrinsic diradical characteristics promote internal conversions in company with intramolecular donor–acceptor interactions, and the hyperfine coupling effect between the dimeric radical-ion pair excitons and adjacent magnetic nuclei assists intersystem crossing.

  @article{ , abstract = {Singlet oxygen (¹O₂) demonstrates great potential for selective wastewater detoxification, which raises the appeal to achieve a controllable, mild, and efficient generation of this reactive species for water decontamination. Herein, we present a novel cascade photoelectrocatalytic (PEC) system operated via the interaction between the photoanodic and cathodic reactions without the addition of chemical precursors, realizing highly efficient ¹O₂ production (79.7 µmol L −1 min −1 ) and low energy consumption (0.052 kWh m −3 -log) for antibiotic degradation. The enhanced 1 O 2 production is proven to benefit from the synergistic effect of multiple activation pathways under PEC excitation. With the combined action of both the built-in electric field and external electric field, the holes in the Z-scheme heterojunction photoanode are maximally retained, and electrons are transferred to cathode to undergo the oxygen reduction reaction (ORR), leading to the production of the crucial reactive oxygen species as intermediates. The occurrence of a cascade reaction is initiated by electrocatalytic 2e − ORR on the cathode and terminated by superoxide species oxidation by holes on the photoanode. The hole-involved 1 O 2 generation pathway circumvents the thermodynamically unfavorable process of traditional 1 O 2 generation.

The optimized 0.75 wt% Cu-Co 3 O 4 /OVs demonstrated exceptional efficiencies in degrading diverse micropollutants through synergistic oxidation pathways involving radicals and nonradical electron transfer process (ETP).

In addition, synergistic oxidation pathways not only enhanced the generation of reactive species but also improved their utilization efficiency by shortening the migration distance of radicals. Such system exhibited remarkable long-term stability (up to 16 h) in wastewater treatment, with its environmental applicability further validated through life cycle assessment and bio-experiments.

Then, water-soluble peptide conjugates were used to catalyze a thiol-ene reaction on cysteine in aqueous media. Finally, we achieved protein labeling via aryl azide excitation both in vitro and at the cellular level using peptide-CzIPN conjugates.

However, due to the electrophilic nature of aldehydes, incorporating aldehyde functionalities directly into DNA is challenging, particularly for highly reactive alkyl aldehydes. Inspired by natural oxidases, we herein developed a controlled oxidation strategy to generate aldehyde-functionalized DNAs from synthetically accessible DNA-conjugated amines in situ. A broad range of DNA-conjugated alkyl and aryl aldehydes were efficiently produced from the corresponding amines using O 2 /laccase/TEMPO, with feasible micromole-scale preparation. Moreover, combining oxidative cleavage of DNA-conjugated secondary and tertiary amines with reductive amination enabled switchable amine–aldehyde transformation and reversible solid-phase bioconjugation of DNA probes. Furthermore, the reactivity “umpolung” from nucleophilic amines to electrophilic aldehydes highlights its potential for synthesizing chemically diverse DNA-encoded libraries (DELs). In summary, the presented controlled oxidation strategy expands the current toolbox to introduce aldehyde functionalities into DNAs within a chemical biological context.}, archive = {J_ANGEW}, author = {Guixian Zhao and Mengping Zhu and Pengyang He and Qigui Nie and Yangfeng Li and Gong Zhang and Yizhou Li}, doi = {10.1002/anie.202507064}, journal = {Angewandte Chemie International Edition}, month = {8}, number = {32}, pages = {e202507064}, shortjournal = {Angew.

  @article{ , abstract = {Photoinitiated homolysis of element–carbon bonds is an important method for the generation of carbon-centered radicals in catalysis and organometallic or polymer chemistry. In this respect, the use of earth-abundant main group elements such as aluminum or silicon is attractive. Generally, subvalent species derived from these typically redox-inactive elements are unstable and within their high-valent configuration +III (Al) or +IV (Si) comparatively strong E─C bonds are formed. Therefore, E─C homolysis usually requires shortwave UV irradiation, which hampers their use as radical sources. Some reports in the literature show that visible-light-induced E─C homolysis is possible when a redox non-innocent ligand (NIL) is coordinated to the organometallic fragment. In a simplified view, the NILs provide chromophoric moieties, which can absorb energy in form of light and subsequently convert it to break the element–carbon bonds. The resulting main group element radicals are in turn stabilized by delocalization of the unpaired electron, effectively lowering the dissociation energy of the E─C bond. In this article, the effects of NILs as mediators for visible-light-induced E─C bond homolysis in main group chemistry are discussed on the basis of selected literature reports, and future opportunities and challenges are highlighted.}, archive = {J_ANGEW}, author = {Jonas O.

The heteroepitaxial growth process produced micelles with kinetically trapped crystalline cores that are thermodynamically less stable than the materials formed via spontaneous nucleation. This was rationalized by determining the previously unknown core lattice of PFDMG micelles, self-assembly experiments, and theoretical lattice energy calculations, providing an insight into the energetic penalty associated with heteroepitaxial growth. These methods for determining the theoretical core lattice energies in these BCP systems could provide a way to screen BCP candidates that can undergo heteroepitaxial growth.

  @article{ , abstract = {Typical nanopore sensing depends on slowed translocation through the pore to acquire effective blockade signals. However, this paradigm often suffers from low signal precision and poor resolution, making it challenging to resolve pools of analytes with diverse, similar structures. Here, we present a non-translocation blockade sensing based on an engineered aerolysin S278K that enables the identification of isomerically diverse ginsenosides—a class of glycoconjugates whose structural characterization has been a persistent challenge in glycoscience. By introducing the S278K mutation, the aerolysin acquires a highly positively charged interior and generates intense electro-osmotic flow and enhanced steric/enthalpic barriers, effectively trapping ginsenoside molecules in the K278-R220 region and preventing their further translocation. This distinct blockade sensing mode significantly improves the detection capability of aerolysin by prolonging residence time (e.g., 43-fold longer), enabling detailed molecular characterization. As a result, we demonstrate the unambiguous identification of 30 ginsenosides differing in glycosyl composition, isomerism, modification, and aglycone, as well as the quantitative analysis of complex ginsenosides in real samples by integrating deep learning.

  @article{ , abstract = {The hydrogenation of CO 2 to methanol has garnered significant interest with respect to the reduction of carbon emissions; however, the high temperatures and pressures typically required diminish the benefits of this approach. In this study, we report a hexagonal close-packed (hcp)-PdMo catalyst that exhibits the highest room temperature catalytic activity for CO 2 hydrogenation to methanol among reported catalysts, with 100% methanol selectivity and without any signs of deactivation. Structural analyses, which included various in situ and ex situ X-ray techniques and infrared spectroscopy, have revealed that Mo and Pd serve as the active sites for CO 2 adsorption and H 2 dissociation, respectively. The CO 2 hydrogenation reaction is facilitated at room temperature on the surface of the hcp-PdMo intermetallic catalyst, where the adjacently arranged Pd and Mo sites play important roles in methanol synthesis. Mechanistic studies, combined with density functional theory (DFT) calculations, have demonstrated that the reaction proceeds via a reverse water-gas shift and subsequent CO hydrogenation (R&C) pathway though a Pd-assisted Mo redox mechanism at room temperature.

However, the catalytic activity of state-of-the-art Pt-based catalysts decreases significantly due to the strong adsorption of N species. In this study, a triple-layer core–shell structured Ru@Ir@Pt model catalyst was employed to demonstrate that the relay electron transfer strategy can decelerate the adsorption of N species and increase AOR activity, a process facilitated by the built-in electric field (BEF) induced by differing work functions that drive the sequential relay of charge transfer across the interfaces between different metals. In situ Fourier Transform Infrared (FTIR) spectroscopy revealed that AOR proceeds primarily via the N 2 H 4 pathway of the G–M mechanism. Both the experimental and theoretical simulation results confirm that relay electron transfer induced by a built-in electric field enables the outermost Pt electron-rich state to reduce the intensity of N adsorbed species and lower the energy barrier of rate-determining step in the AOR, resulting in excellent activity with a mass activity reaching up to 363.5 A g −1 .

Through multiscale techniques combining XRD, XAS, and 6 Li solid-state NMR, we identify the structural degradation in spent NCM622 and monitor both long- and short-range structural evolution during repair. Our findings reveal that degradation predominantly occurs through Ni migration into Li octahedral sites, while Co and Mn demonstrate relatively lower occupancies in the Li layer. Such occupancies are primarily responsible for structural disorder and cubic-symmetry domain formation within the spent material. The repair process is demonstrated to involve re-lithiation, oxygen capture, increased transition metal (TM) oxidation states, and the migration of TM ions from the Li layer back to the TM layer, followed by cation diffusion. Both temperature and lithium compensation ratio are identified as critical factors promoting these processes.

  @article{ , abstract = {Polyether electrolytes with high Li + conductivity and excellent interfacial contact have garnered significant attention. Yet further applications of such electrolytes in high-voltage lithium metal batteries are severely hindered by the instability of the electrolyte and electrolyte/electrodes interphases. Here, we report a novel high-voltage polyether electrolyte with a “rigid exterior, soft interior” design, which involves a 3D F-contained network as a rigid exterior framework, and a unique solvation structure with intensified Li + -anion coordination as a soft interior within the framework. The achieved electrolyte demonstrates an ionic conductivity of 1.13 mS cm −1 at 25 °C, a Li + transference number of 0.85, and an extended electrochemical stability window of over 5 V. Besides, such a designed polyether electrolyte further induces salt-philic, solvent-phobic interfacial films for stabilizing electrolyte/electrode interphases. An exceptional cyclability in a Li||Li cell for over 4000 h, and a preferable capacity and cyclability in even 4.6 V Li||LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) quasi-solid-state batteries (QSSBs) are demonstrated.

  @article{ , abstract = {Intrinsically stretchable organic solar cells (IS-OSCs) are among the most promising technologies for wearable power applications. However, the development of electron acceptors that simultaneously meet the demands for high performance and mechanical stretchability remains a significant challenge. In this study, we creatively synthesized three oligomeric acceptors with flexible linkers (2YF-Br, 4YF-T, and 6YF-BT) and achieved both high efficiency and mechanical robustness in IS-OSCs. Benefiting from an improved fibrous morphology and excellent charge dynamics, rigid OSCs based on 4YF-T demonstrated a superior power conversion efficiency (PCE) of 18.76%, outperforming devices based on 2YF-Br and 6YF-BT. Additionally, the thermal stability of rigid OSCs progressively improved with increasing molecular weight, from 2YF-Br to 6YF-BT. Furthermore, the enlarged molecular weight of the acceptors significantly enhanced mechanical stretchability, with crack-onset strain (COS) values of 16.11%, 20.62%, and 25.92% for 2YF-Br, 4YF-T, and 6YF-BT, respectively. Importantly, as molecular weight increased, the mechanical robustness of IS-OSCs also improved, with 6YF-BT-based devices achieving remarkable stretchability (strain at PCE 80% = 35%).

  @article{ , abstract = {The operational stability of n–i–p perovskite solar cells (PSCs) under heat, air, and humidity has notably improved over recent years. Yet, performance degradation under light and voltage bias remains a concern for their commercial deployment. One of the main causes of such degradation relates to mobile ions in the perovskite film, which can trigger ion migration and self-accelerating chemical degradation. Here, we propose an energetics modulation strategy by developing the electron-withdrawing pyridinecarboxaldehyde oxime (PO) ligand for FAPbI 3 -based perovskites. The introduction of PO ligands increases the ionization potential of the perovskite, inhibiting the generation of mobile ions during the crystallization process and subsequent device operation. Furthermore, this additive promotes the reaction between PbI 2 and organic salts, which can help to regulate the energy level of perovskite and facilitate charge transport to the contact stacks. As a result, the optimized n–i–p PSCs exhibit a high efficiency of 26.13% and maintain over 88% of their initial efficiency after 1000 h maximum power point (MPP) tracking test under 1 sun illumination.

In this study, the rational manipulation of Cu defect sites was realized for the selective formation of C 2 H 5 OH and C 2 H 4 . Low-coordination amorphous and medium-coordination grain-boundary Cu defect sites with different *OH affinity were found to play a decisive role in the selective protonation of CH 2 CHO*. In particular, grain-boundary-rich Cu (denoted as Cu-1) that weakly adsorbed *OH and CH 2 CHO* favored the protonation on β-C of CH 2 CHO*, leading to the selective production of C 2 H 5 OH. In contrast, amorphous Cu defect sites (denoted as Cu-3) showed strong *OH adsorption and then strong CH 2 CHO* adsorption, facilitating C−O breaking and C 2 H 4 formation. In the membrane electrode assembly (MEA) configuration, a remarkably high full-cell energy efficiency (EE) of 29.0 % for C 2 H 5 OH on Cu-1 and an impressive high full-cell EE of 25.6 % for C 2 H 4 on Cu-3 were observed.

The inoculated Li 1.2 Mn 0.6 Ni 0.2 O 2 exhibits an initial coulombic efficiency of 85% and maintains ultra-high stability with 100% capacity retention after 500 cycles.

Consequently, achieving blueshifted and enhanced emission in π-conjugated systems remains a significant challenge.

Upon introducing methanol into the nanopores of CTFs, a blueshift in emission from 507.0 to 485.5 nm, accompanied by enhanced intensity, is observed under compression up to 1.22 GPa, distinctly contrasting the redshifted and quenched emission typically observed in compressed pristine CTFs and other crystalline porous materials (CPMs). Combined experimental and theoretical analyses reveal that methanol can weaken the interlayer π–π stacking and intralayer conjugation of CTFs by forming weak interactions with CTFs, such as hydrogen bonding, to realize the interlayer slip and intralayer distortions of CTFs, which results in the blueshifted and enhanced emission. This strategy also proves effective with other molecular insertions, offering a general approach to achieving anomalous piezochromic luminescence in CTFs.

  @article{ , abstract = {Sluggish interfacial reaction kinetics and unstable electrode/electrolyte interphases seriously hinder the practical applications of sodium-metal batteries (SMBs) with extremely low-temperature performance. Here, we propose an ester-based electrolyte featuring solvent-anion synergistic and self-purification functions that empowers SMBs to operate stably at record-low temperatures down to −60 °C. The weakly solvating fluorinated solvent (ethyl difluoroacetate, [EDFA]) constructs an anion-dominated solvated structure, where the high-donor-number trifluoroacetate anion (TFA − ) synergistically reduces the Na + desolvation energy barrier while triggering the defluorination of EDFA. This dynamic process in situ generates inorganic components (e.g., NaF) in the solid electrolyte interphase (SEI). Further, tris(trimethylsilyl) phosphite (TMSPi) additive effectively scavenges corrosive HF species through a self-purification mechanism, ensuring durable cathode-electrolyte interphase formation. As a result, the ester-based SMBs render a capacity retention of 96% at −40 °C (relative to the room-temperature capacity), exceptional rate capacity (81.64 mAh g −1 at 400 mA g −1 with 70.26% retention at −40 °C, which is the best rate capability at extremely low temperature compared to other ester-based SMBs), and extended cycle ability (>300 cycles at −40 °C and 100 cycles at −60 °C).

Their diverse and non-covalent structures allow for precise modulation of CT with external stimuli. Despite their potential, achieving effective CT modulation in supramolecules through external stimuli remains challenging due to a lack of rigid systems with a predictable response to such stimuli. To address this challenge, we explore the use of porphyrin-based supramolecular structures and their CT responses to light illumination. By incorporating rigid ligands to increase the spatial distance between two porphyrin units, we diminish their interactions, fabricating porphyrin-contained cages that exhibit a higher efficiency of electron-hole pair separation compared to the monomer in solid state. Leveraging this advantage, a more effective photo-responsive CT is achieved for cages in solid-state junctions compared to that of monomers. The current through cage junctions reduces upon illumination. Theoretical calculations indicate that the reduction in conductivity arises from an increased energy offset between the molecule and electrode under light irradiation. Moreover, the photo-responsive CT can be finely tuned by adjusting the metal ion coordinated within the porphyrin and the distance between the cage and the electrode.

Through a heteroepitaxial growth process, ZIF-8 was precisely coated on silicon micromotors, a typical model for EMNMs, significantly enhancing their ion tolerance.

Additionally, the micromotors maintained stable, controllable motion under 980 nm NIR light, even when passing through an artificial blood vessel covered with biological tissues.

Compared to protonated L4, the rational deuterated molecule (BT-12D) maintains SWIR photoresponse to ∼1.7 µm and exhibits lower stretching vibrational frequency (2350 cm −1 vs. 3063 cm −1 ), resulting in reduced recombination and 40% increase in specific detectivity ( D * ) at 1.3 µm for PDPPDTP: BT-12D-based organic photodetectors (OPDs). Likewise, deuterated L2-eC9-10D-based OPDs blending with PTB7-Th exhibit 14% higher D * (1.24 × 10 12 Jones at 1.2 µm) and faster rise/fall time (1.0/1.2 µs) than protonated devices (1.09 × 10 12 Jones; 1.6/1.7 µs). The optimized D * of deuterated OPDs is comparable to and even better than those of commercial detectors at 0.9–1.2 µm, while the corresponding response time is the fastest value reported for SWIR OPDs. These results highlight the broad applicability of deuteration as an effective strategy to suppress nonradiative decay pathways in SWIR organic semiconductors, unlocking new opportunities for sensitive SWIR optoelectronics.}, archive = {J_ANGEW}, author = {Zhenzhen Zhang and Yujie Yang and Tengfei Li and Huiqing Hou and Yifei Geng and Qianqian Lin and Yuze Lin}, doi = {10.1002/anie.202507637}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {31}, pages = {e202507637}, shortjournal = {Angew.

However, their practical applications are often limited by low photoluminescence quantum yields (PLQYs) caused by insufficient exciton confinement and extended charge-carrier diffusion lengths within the 2D anionic layers. To overcome these limitations, we developed a novel multicomponent structural engineering strategy that led to the design of [AMP] 2 Cu 2 PbX 8 double perovskites [AMP = 4-(Aminomethyl)piperidinium, X═Br − and I − ]. These materials feature [Cu 2 PbX 8 ] 4− monolayers consisting of alternating corner-sharing [Cu 2 X 6 ] 4− dimers and [PbX 6 ] 4− octahedra. Compared to the negligible luminescence observed in 2D [AMP]PbX 4 analogs, the [AMP] 2 Cu 2 PbX 8 compounds demonstrate strong broadband yellow-orange emission originating from self-trapped excitons (STEs), achieving high PLQYs exceeding 48%. Comprehensive spectroscopic analysis and theoretical studies reveal that the incorporation of [Cu 2 X 6 ] 4− dimers simultaneously enhances exciton binding energy, electron/hole effective mass, exciton confinement efficiency and STE self-trapping depth, which are all critical factors contributing to the improved PLQY.

Here, we present a system-wide analysis of short-range cross-links, demonstrating their intrinsic correlation with protein secondary structure. We introduce the X-SPAN (Cross-link Structural Pattern Analyzer) software, which integrates publicly available XL-MS datasets from system-wide experiments with AlphaFold-predicted protein structures.

Specifically, α-helices exhibit periodic cross-linking patterns consistent with their characteristic helical pitch, whereas coils and β-strands display nearly monotonic distributions. A context-dependent protein grammar reinforces short-range cross-link specificity. Short-range cross-links can enhance the statistical inference of secondary structures within integrative modeling workflows. Additionally, our work establishes a framework for benchmarking AlphaFold's local prediction accuracy and provides novel quality control criteria for XL-MS experiments.

The carbamate deprotonation catalyzed by the active site thiolate initiates the redirected cleavage. The C-terminal part of the inhibitors remains covalently attached to the protease.

Herein, we identified reducibility of GaO x as the key descriptor affecting the above catalyst features. Oxidized GaO x species are more active than reduced GaO x in the recombination of two H species formed from propane, which is the rate-limiting step in the PDH reaction. This process is further accelerated by Pt. The reduction of GaO x with time on propane stream leads to catalyst deactivation. Easily reducible GaO x also tend to form PtGaO x under PDH conditions, from which Pt atoms present in fresh catalysts cannot be completely recovered during oxidative regeneration, which is detrimental to catalyst durability. Regardless of the reaction atmosphere, Pt single atoms exist on the surface of PtGaO x -containing catalysts with hardly reducible GaO x .

However, the chemical stability of the wide-bandgap insulator Li 2 CO 3 severely hinders the CO 2 ER. To address this challenge, this study proposes a lattice compression strategy in which electronic localization accelerates the CO 2 RR, thereby enhancing Ir–O coupling and inducing the formation of low-crystallinity Li 2 CO 3 , ultimately optimizing the CO 2 ER process. This approach enables the Li–CO 2 battery to achieve an ultralow overpotential of 0.33 V and an exceptionally high energy efficiency of ∼88.7%. Moreover, even after over 1100 h of operation, the battery maintains a stable charging potential of 3.3 V, representing the best performance reported to date. Through in situ and ex situ characterizations combined with theoretical calculations, we reveal that lattice compression leads to changes in the coordination environment, thereby enhancing electronic localization effects. This accelerates Li + migration near the catalyst surface, facilitating its rapid participation in CO 2 RR.

Herein, we reveal for the first time that several CYP152 family members can directly degrade various aromatic pollutants without any carboxyl group, exhibiting novel aromatic hydroxylation and dehalogenation activities.

While enzymatic pericyclic reactions have been increasingly reported in recent years, there are only a few examples of enzyme-mediated electrocyclization reactions. The 2,2-dimethyl-2 H -pyran (DMP) ring plays a significant role in constituting many bioactive fungal and plant natural products. In this study, we characterize the vsc biosynthetic gene cluster of the DMP-containing natural product versicamide A ( 1 ) in Aspergillus versicolor DL0022. The biosynthetic route for DMP formation and the biochemical functions of the involved enzymes are fully elucidated. Specifically, we reveal that the berberine bridge-like oxidoreductase VscB mediates a crucial oxidative process, followed by an electrocyclization to form a C─O bridge bond, thereby affording the key DMP ring. Structural simulation, molecular modeling, mutational analysis, and quantum chemical calculations elucidate the oxidative electrocyclization mechanism.

  @article{ , abstract = {The built-in electric field (BEF) is proposed as a critical design parameter for optimizing small-molecule cathode interlayer materials (SM-CIMs) in organic solar cells (OSCs). By strategically transforming imidazole-functionalized triads from a donor-acceptor-donor (D-A-D) to an A-D-A configuration and replacing the A unit with a more electron-deficient moiety, we developed three triads: (TBT) 2 NDI, (NDI) 2 TBT, and (PDI) 2 TBT, each exhibiting progressively enhanced BEF, along with improved conductivity, work function (WF) adjustability, energy level alignment, and crystallinity. Additionally, the A-D-A triads facilitate superior electronic communication with both non-fullerene acceptors (NFAs) and polymer donors, enhancing photoexcitation utilization and reducing triplet state formation. Consequently, transitioning from (TBT) 2 NDI to (NDI) 2 TBT and then to (PDI) 2 TBT significantly boosts OSC efficiency and operational stability. Notably, devices with (PDI) 2 TBT and (NDI) 2 TBT retain 85.0% and 82.3% of their peak efficiencies, respectively, far exceeding the (TBT) 2 NDI-based device (65.9%) at an interlayer thickness of approximately 105 nm. Furthermore, (PDI) 2 TBT exhibits excellent compatibility with various active layers, and an outstanding performance of 20.10% is recorded in the PM6:L8-BO:BTP-eC9 system.

In a study of proton exchange membrane fuel cell (PEMFC), with a focus on the kinetically sluggish O 2 reduction reaction in the cathode, operando EC-MRI quantitatively illustrates the interplay between power output, water content, and TPB evolution. It reveals that the TPB maps undergo significant spatial and dynamic variations, with TPB deterioration, rather than apparent water accumulation, directly triggering flooding, as proved using catalysts with different water generation and adsorption capabilities.

  @article{ , abstract = {Enzyme-responsive active transporting nanomedicines have shown promise in overcoming the tumor-dense extracellular matrix barrier by inducing cancer cells’ intercellular transcytosis to deliver drugs deep into solid tumors. However, nanomedicine only responsive to the cancer cell-related enzyme is not very effective in pancreatic tumors because successive transcytosis cannot be established among the cancer cells, which are scattered in a large number of cancer-associated fibroblasts (CAFs). Here are reported dual-enzyme-responsive 7-ethyl-10-hydroxycamptothecin (SN38)-polymer conjugates capable of inducing transcytosis among cancer cells and CAFs to infiltrate pancreatic tumors efficiently. The conjugates are zwitterionic for long blood circulation. Once in the tumor, the γ-glutamyl transpeptidase (GGT) overexpressed on the tumor endothelial and cancer cells, or the fibroblast-activated protease (FAP) on CAFs, can cleave the γ-glutamylamide or the prolylglycine dipeptide amides, producing primary amines. The cationized conjugate then induces transcytosis among cancer cells and CAFs, establishing successive intercellular transport to infiltrate the tumor. The conjugates' enzyme reactivity and overall hydrophobicity determine their cationization and transcytosis behaviors. The conjugates with high hydrophobicity and fast cationization show potent antitumor activity in pancreatic cancer patient-derived xenograft and orthotopic tumor models.

Unlike the conventional iron atomization process, the reactive nitridation process can generate thermodynamically stable Fe 2 N intermediates by nitriding the initially formed iron oxide, thereby impeding subsequent thermal atomization to fabricate Fe 2 N nc /Fe 1 -N-C catalysts. Compared to the conventional SAC Fe 1 -N-C with Fe-N 4 active sites, the Fe 2 N nc /Fe 1 -N-C nanorods are more active for oxygen reduction reaction (ORR), yielding a record high half-wave potential of 0.957 V versus RHE in alkaline condition. The Fe 2 N nc /Fe 1 -N-C nanorods can be utilized as air-cathode catalysts for Zn-air batteries with a charge-discharge gap of only ∼0.658 V and outstanding cyclability up to 1000 h.

Here, we report the solvent-free synthesis of the first neutral alkali metal monohydrogen porphyrin, which was selectively obtained by reaction of lithium vapor with thin films of tetraphenylporphyrin (H 2 TPP) under ultrahigh vacuum (UHV) conditions.

Contrary to conventional d-band center predictions, we demonstrate that ferromagnetic ordering fundamentally dictates catalytic activity by stabilizing triplet O 2 adsorption and lowering spin-forbidden transition barriers. The Ni (210) facet exhibits superior ORR performance (half-wave potential: 0.842 V vs. RHE), outperforming Ni (310) and Ni (520) due to its optimized d-band center and enhanced saturation magnetization. External magnetic fields amplify this effect, yielding a 28% current density enhancement for Ni (210)—nearly triple that of Ni (520). Spin-polarized DFT calculations reveal that ferromagnetic ordering reduces the potential-determining step energy barrier for *OH desorption by 7.0%, overriding coordination-number effects.

  @article{ , abstract = {Viral binding and membrane fusion are essential steps in viral infection, mediated by viral proteins that bind to host cell receptors and facilitate the fusion between viral and host membranes. Targeting these steps for the development of new antiviral strategies requires methods that enable investigating virus-membrane interactions under in-situ conditions, while providing mechanistic insights on a molecular level. Here, we demonstrate the use of surface-enhanced infrared absorption (SEIRA) spectroscopy combined with tethered bilayer lipid membranes (tBLMs) for the label-free detection of virus-membrane interactions, using the Influenza A/X-31 virus (IAV) as a model. Exploiting the nanometer-scale surface-sensitivity of SEIRA, we detect the vibrational fingerprint of IAV's hemagglutinin (HA) glycoprotein, as it specifically binds to sialic acid receptors of the ganglioside GD1a in the tBLM, mimicking the host membrane. Triggering viral fusion via a pH change, we identify structural changes of HA engaging with the host membrane model. Moreover, by constructing the tBLM from deuterated lipids, we utilize the vibrational isotope effect and distinguish between viral and model membrane, providing a basis to track lipid mixing.

However, the formation of stable α-FAPbI 3 requires annealing at a temperature of at least 150 °C, which can induce significant residual stress and make the process incompatible with plastic substrates, resulting in poor crystal quality and compromised mechanical properties. To address these issues, we present a novel approach using methylammonium chloride (MACl) vapor-assisted lead iodide (PbI 2 ) to form homogeneous intermediate phases (MAPbCl 3 and Pb 3 I 8 ). This method optimizes the reaction pathway; accordingly pure α-phase perovskite can be completely formed at 100 °C, contrasting with conventional MACl component engineering in organic amine salt solution. We have intensively deciphered the reaction pathway leading to intermediate phase formation, as well as the nucleation and phase transition processes into the photoactive perovskite at 100 °C. Additionally, we have conducted a comprehensive study on temperature-dependent residual stress and cation reaction competition, meanwhile extensively dissecting the competitive implication of interface mismatch and lattice defects leading to residual stress and cation component inhomogeneity.

  @article{ , abstract = {The low immunogenicity and immunosuppressive phenotype of breast cancer significantly limit the effectiveness of immunotherapy. This study reveals that histone deacetylases (HDACs) are upregulated in breast cancer, while lower levels of HDACs and higher levels of programmed cell death ligand 1 (PD-L1) are associated with better patient prognosis. Moreover, Trichostatin A (TSA) is confirmed to suppress HDACs and increase PD-L1 expression. Building on these insights, a self-promoting targeted immunostimulant (SPT-IS) is developed to activate breast cancer immunity by epigenetically upregulating PD-L1. SPT-IS can selectively accumulate in PD-L1-overexpressing breast cancer cells for co-delivery of Chlorin e6 (Ce6) and TSA. Notably, SPT-IS-induced epigenetic upregulation of PD-L1 creates a self-promoting tumor-targeting loop that enhances drug delivery efficiency. Besides, SPT-IS generates reactive oxygen species (ROS) to kill tumor cells and release damage-associated molecular patterns, increasing tumor immunogenicity. Additionally, the epigenetic regulation ability of SPT-IS upregulates immunomodulatory cytokines and stimulates T cell cytotoxicity for immune activation. Immunological results confirm robust immunomodulatory effects of SPT-IS, significantly enhancing tumor-infiltrating lymphocytes recruitment and proliferation, leading to notable anti-tumor efficacy.

Nonetheless, phenotypic protein degrader discovery (PPDD) faces practical hurdles, such as synthetic complexity in generating chemically diverse libraries and difficulties in reliably identifying degradation-driven phenotypes in direct-to-biology (D2B) assays. In response to these challenges, we developed an integrated PPDD platform that combines optimized solid-phase parallel synthesis with a robust D2B screening workflow. Leveraging photocleavable linkers and versatile synthetic strategies, this platform facilitates rapid generation of chemically diverse, ready-to-screen bifunctional molecule libraries requiring minimal purification. As a proof of concept, we synthesized and phenotypically screened 130 cereblon-recruiting molecules, leading to several promising protein degradation-dependent hits. Subsequent hit optimization and target identification validated compound 12–60 as a structurally novel GSPT1 degrader with compelling cellular activity. Overall, our integrated platform represents an efficient and practical toolkit for PPDD, establishing a versatile foundation to accelerate future campaigns and expand the degradable proteome.}, archive = {J_ANGEW}, author = {Baoli Ding and Jiawen Hu and Rongtian Zhang and Binyan Shou and Mengdie Chen and Li Jiang and Meng Yuan and Bo Yang and Qiaojun He and Ji Cao and Cheng-Liang Zhu}, doi = {10.1002/anie.202424118}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {31}, pages = {e202424118}, shortjournal = {Angew.

  @article{ , abstract = {Herein, we report a detailed investigation of the photomediated transformation of indazoles to benzimidazoles through a nitrogen–carbon transposition. This phototransposition is known to occur in low yield when 1 H -indazoles are subjected to high-energy UVC irradiation. The 2 H -tautomer of indazole absorbs light more strongly than the 1 H -tautomer at longer wavelengths. We leveraged this improved absorbance profile to develop a general system for the high-yielding conversion of N2-derivatized indazoles (prepared from the corresponding 1 H -indazoles) to the corresponding benzimidazoles under UVB or UVA irradiation in up to 98% yield. Investigation of the substrate scope revealed a strong correlation between reaction yield and electron density at N2 of the indazole substrate, suggesting the importance of the availability of the lone pair at this position for reaction efficiency. In addition, evaluation of wavelength-dependent reactivity through the generation of a photochemical action plot revealed that the highest conversion does not only occur at the substrate's maximum absorbance wavelength but also on its red-side, enabling the use of longer wavelength irradiation to achieve high yields. Building on these insights, a continuous flow protocol was established that enables the phototransposition on preparative scale.}, archive = {J_ANGEW}, author = {G. Logan Bartholomew and Sojung F.

  @article{ , abstract = {Water drops spontaneously accumulate charges when they move on hydrophobic dielectric surfaces by slide electrification. Slide electrification generates electricity with possible applications on tiny devices. The potential of up to 1 KV generated by slide electrification alters wetting and drop motion. Therefore, it is important to know the factors that affect slide electrification. To find out how surfactants affect slide electrification, we measured drop charges of aqueous drops containing cationic CTAB, anionic SDS, and neutral C 8 E 3 sliding on different hydrophobic surfaces. The result is: addition of surfactant significantly reduces the spontaneous charging of moving water drops. Based on zeta potential measurements, confocal microscopy of deposited surface-active dyes and drop impact studies, we propose that several factors contribute to this suppression of charge separation: (1) Surfactants tend to lower the contact angles, which reduces charge separation. (2) Surfactant adsorption at the solid-liquid interface can reduce the density of primary ions, particularly for anionic surfactants. (3) Anionic and neutral surfactants are mostly transferred to the liquid-air interface at the rear of the sliding drop, retaining primary ions within the drop. (4) Deposited cationic surfactant directly reduces the charge of the drop.}, archive = {J_ANGEW}, author = {Xiaomei Li and Zhongyuan Ni and Xiaoteng Zhou and Lisa S.

  @article{ , abstract = {Organic molecules are promising candidates for aqueous organic redox flow batteries (AORFBs) due to their structural versatility, tunability, and reliance on earth-abundant elements for sustainable energy storage solutions. However, achieving stability for organic molecules in aqueous batteries remains challenging due to water-induced degradation. The conjugated systems with enhanced rigidity, such as anthraquinone or phenazine derivatives, have shown improved stability, yet often exhibit unwanted restructuring reactions in the reduced state due to overly high electron densities, leading to the loss of redox activity. In the present work, we introduce a resonance hybrid, 2,3-dihydroxyl substituted phenazine dication (HSPC), whose redox center is distributed among different resonance forms between phenazine and quinone to enable efficient reversible electron transfer in aqueous environments. The electrochemical synthesis, resonance structure, and key properties of HSPC were investigated through a framework of combined electrochemical measurements, spectroscopic analysis, and theoretical studies. A 1.4 M electron concentration cell based on HSPC exhibits a low capacity decay rate of 0.0009% per cycle, 0.006% per day.

  @article{ , abstract = {The conversion of conventional “always-on” cyanine dyes into activatable NIR probes with low inherent fluorescence remains challenging, resulting in poor imaging contrast and nonspecific response in vivo. We herein report a 5- exo-trig cyclization strategy to create diverse activatable heptamethine cyanine probes with “zero” intrinsic background fluorescence for high-contrast bioimaging. This intramolecular ring-closure approach imparts a built-in switch to regulate the fluorescence of cyanine dyes, which predominantly exist in the nonfluorescent closed-loop form at pH over 5.0 and are not affected by environmental polarity and protein interaction, thereby reducing false-positive fluorescent signals. Upon reaction with various biomarkers, including methylglyoxal (MGO), hydroxyl radical (·OH), and adenosine triphosphate (ATP), they could rapidly transform into fluorescent open-loop structures, showing significant NIR fluorescence enhancement (up to 184-fold). Furthermore, we extended this strategy to develop a variety of NIR-II ATP-activatable cyanine probes for the first time, as well as a theranostic probe 57 using host–guest chemistry. Probe 57 not only sensitively monitored ATP levels in inflammatory bowel disease (IBD) with a high signal-to-background ratio of 48/1, but it also precisely detected extracellular ATP in stools.

  @article{ , abstract = {The conventional industrial synthesis of formic acid is an energy-intensive process that contributes to the CO 2 footprint. As an alternative method, the electrochemical reduction of carbon dioxide (eCO 2 RR) to formic acid has emerged as a viable means to reduce atmospheric CO 2 concentrations and advance the energy transition to a circular, carbon-neutral economy. Despite considerable progress in this field, the scale-up of electrolyzers from laboratory prototypes to commercial-scale production remains an important challenge. Thus, this technoeconomic analysis provides a detailed evaluation of the economic viability of upscaling the electrolyzer size to an industrial level, determining whether the eCO 2 RR process can economically compete with the conventional industrial production of formic acid. The proposed technoeconomic assessment employs a bottom-up approach based on realistic cost models using the three most successful designs: dual flow (DF), direct formic acid production (DFAP), and zero-gap (ZG) electrolyzers. The results from this study underscore the necessity of implementing multiple-cell stacking to economically compete with established industrial processes. Among the three studied designs, DFAP and, to a certain extent, DF are promising. Although the scalability of the DFAP electrolyzer may initially appear inadequate, it holds potential for commercial application, particularly if technical improvements in the center compartment and solid-state electrolyte are materialized.}, archive = {J_ANGEW}, author = {Urbain Nzotcha and Sergio Sanz and Hermann Tempel and Rüdiger-A.

  @article{ , abstract = {Metal-based heterogeneous catalysts have been commonly adopted for Fenton-like oxidation of organic pollutants, but generally suffer from inadequate activity in practical water treatment applications due to surface passivation by accumulated pollutants and sluggish redox cycling of active metal. Here, we observed an unusual phenomenon of pollutant-induced activity enhancement for copper oxide (CuO) in H 2 O 2 activation and phenol degradation, which is in sharp contrast to considerable activity decay of Fe 2 O 3 catalyst. The CuO was found to stabilize and activate phenol via ligand-to-metal charge transfer route, generating surface-bound phenoxyl radicals for further mediating the H 2 O 2 activation and enabling a rapid regeneration of low-valent Cu. Based on this principle, a Fe-Cu bimetal oxides catalyst was elaborated to further augment the catalyst-phenol interaction towards self-activated Fenton oxidation. The optimal catalyst achieved 14-time faster pollutant degradation rate and 2 order-of-magnitude higher H 2 O 2 utilization efficiency than the Fe 2 O 3 control.

By designing 2-indolylacetates as a new class of four-carbon platform molecules for higher-order cycloadditions and modulating the nucleophilicity of benzofuranyl azadienes, we achieved the catalytic asymmetric synthesis of chiral indole-fused eight-membered rings and eleven- to fourteen-membered macrocycles in high yields with good enantioselectivity.

Concurrently, these cooperative effects drive the observed giant NTE, while the resulting hexagonal-closed-packed ( hcp ) K + sublattice further enhances structural contraction.}, archive = {J_ANGEW}, author = {Xin Liu and Yi-Chang Yang and Qian-Qian Liu and Shuang Zhao and Tong Yu and Li-Ming Wu and Ling Chen}, doi = {10.1002/anie.202507107}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {30}, pages = {e202507107}, shortjournal = {Angew.

  @article{ , abstract = {Bifunctional ligands that can coax protein–protein interactions have become attractive therapeutic modalities. Herein, we describe conformationally defined helix dimers as proteomimetic molecular glues . The helix dimers can be rationally designed to engage helical protein interfaces. We previously described a synthetic Sos protein mimic, CHD SOS , as a Ras ligand that inhibits wild-type and oncogenic Ras signaling. This Sos proteomimetic consisted of a crosslinked helix dimer (CHD) that reproduced two helical domains, termed αH and αI, from Sos. The native αH helix of Sos constitutes the primary contact surface for Sos, while αI has minimal engagement. We conjectured that the αI domain of CHD SOS could be reengineered to preserve Ras binding, while engaging another protein to fully leverage the contact residues available in a proteomimetic. Herein, we incorporate a second distinct binding epitope into CHD SOS , thereby generating a bispecific proteomimetic. This secondary epitope was designed based on the p53 activation domain to engage the E3 ligase MDM2 and induce complexation with Ras. The resulting lead proteomimetic, CHD BI4 , associates with both MDM2 and Ras and demonstrates reduction of cellular Ras levels.

Systematically theoretical calculations and experimental studies reveal that the fluorination-assisted ammonium molecule could form a stronger interaction with perovskites and thereby arrange the dipole alignment on the superficial layer of perovskites, which could simultaneously ameliorate the passivation effect and energy level alignment of the perovskite and hole transport layers, thereby suppressing interface recombination. Meanwhile, the coordinated bonding between the ammonium and hole transport layer facilitates charge transfer at the heterojunction interface by offering additional carrier transport channels.

Prior mechanistic studies of cobaloxime catalysis have revealed that cobaloxime(II)-catalyzed hydrogen atom transfer (HAT) process can control the site-selectivity and chemoselectivity of radical transformation. However, the relevance of HAT to the enantioselectivity is seldom reported. Herein, our density functional theory studies of the cobaloxime-chiral amine co-catalyzed enantioselective coupling of the enamine radical cation with alkene proved that it is the HAT step that determines the enantioselectivity, instead of the previously proposed radical addition. Because the metal–alkene-coupled (MAC) radical addition is a reversible process while the followed by HAT is the rate-determining step. Moreover, computational studies suggest that the dynamically changing hydrogen bonding between the radical cation and cobaloxime plays a significant role in harnessing the reactivity and tuning the enantiocontrol. The intra- and inter-molecular hydrogen bonding between the iminium and the cobaloxime fragments contributes to the lower energy barrier of MAC radical addition. Structural analysis and quantitative steric-electronic effect dissection jointly unveiled that the stronger intermolecular hydrogen bonding between the aminium and the cobaloxime fragments is the dominant factor that stabilizes the ( R )-HAT transition state and guarantees high enantioselectivity.}, archive = {J_ANGEW}, author = {Zhao Liu and Long Zhang and Sanzhong Luo and Xiaotian Qi}, doi = {10.1002/anie.202506268}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {30}, pages = {e202506268}, shortjournal = {Angew.

  @article{ , abstract = {Solving the dilemma between efficacy and cytotoxicity of cationic colloidal vectors is one of the biggest challenges in gene delivery. Cationic dendrimer assemblies with hierarchical structure, smart and biomimetic behaviors have been developed for drug/gene delivery in vivo. Among different dendrimer assemblies, the dendrimer-based nanogels were not intensively studied due to complicated synthesis and unknown properties. Here, for the first time, low-generation dendrimer nanogels with high yield and purity, tunable size, uniform morphology, and good colloidal stability were synthesized using the emulsion-free method, which cannot be obtained by the miniemulsion method. Importantly, the dendrimer nanogels integrate the advantages of low-generation dendrimer and stimuli-responsive polymer, thus achieving dual-active groups, o -hydroxyl amine units, temperature-responsiveness, polyampholyte property, and self-triggered aminolysis. With these unique properties, dendrimer nanogels can “temporarily” acquire high charge density through the covalent crosslinking of low-generation dendrimer for improved DNA compression, promoted cell internalization and lysosomal escape, and efficient DNA delivery, followed by self-triggered aminolysis into small dendrimers to control DNA release, reduce cytotoxicity, and facilitate metabolism in vivo. Compared to high-generation dendrimers, low-generation dendrimer nanogels display higher gene transfection and therapeutic efficacies, and lower side effects simultaneously. This work provides a facile strategy for the preparation of low-generation dendrimer nanogels that break up the contradiction between efficacy and cytotoxicity of cationic colloidal vectors in gene therapy. This innovative approach to construct low-generation dendrimers into smart dendrimer nanogels will have broad applicability in clinical translation.}, archive = {J_ANGEW}, author = {Xin Li and Zhijun Ouyang and Laura Hetjens and Ming Ni and Kuailu Lin and Yong Hu and Xiangyang Shi and Andrij Pich}, doi = {10.1002/anie.202505669}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {30}, pages = {e202505669}, shortjournal = {Angew.

Using oxygen-deficient TiO 2 under an air-level (20%) O 2 atmosphere, we achieved a urea generation rate of 54.31 mg g cat −1 h −1 with 100% selectivity. This rate is 38.52 times higher than under oxygen-free conditions, while further increasing the O 2 level significantly reduces selectivity.

  @article{ , abstract = {Photocatalytic oxidation of methane (POM) to CH 3 OH provides a promising pathway for sustainable chemical industry, while uncontrollable generation of reactive oxygen species (ROS) would proceed at the expense of compromised catalytic activity or selectivity of POM. Herein, we precisely control the type of as-formed ROS by introducing Au single atoms (SAs) on CuO x /ZnO (Au 1 -CuO x /ZnO), to simultaneously achieve high selectivity and productivity of CH 3 OH in POM. In situ characterizations and theoretical calculations revealed that the introduced Au SAs significantly altered the electronic structure of Cu atoms, leading to an energy level rearrangement of Cu 3d orbital and the upshift of d-band center, which increased the energy levels of bonding and antibonding states of Au 1 -CuO x /ZnO-*OOH. Thus, the hybridization between Cu active sites and the key intermediate *OOH was significantly enhanced, especially for the orbital hybridizations of d z 2 -p z and d xz /d yz -p x . This facilitated the dissociation of O─O to form *OH intermediate rather than the direct desorption of *OOH, thereby ultimately determining the ROS type in aerobic POM. Additionally, the asymmetric electronic structure of Au 1 -CuO x /ZnO could also lower the first C–H dissociation energy by structural polarization of CH 4 molecules.

This complex elevated the half-maximal inhibitory concentration (IC 50 ) against L929 cells from 9.4 to over 128 µg mL −1 while maintaining a minimum inhibitory concentration (MIC) of 2 µg mL −1 against methicillin-resistant Staphylococcus aureus (MRSA). NMR and UV–vis spectroscopic analyses confirmed that DY6 ’s aromatic backbone is encapsulated within the hydrophobic cavity of SβCD . Isothermal titration calorimetry revealed that size compatibility and electrostatic interactions are essential for stable complex formation and enhanced biocompatibility. Importantly, DY6@SβCD exhibited no resistance development over 14-day serial passages against S. aureus , significantly outperforming norfloxacin. In biofilm-based MRSA-infected wound and corneal models, DY6@SβCD more effectively reduced bacterial load and inflammation compared to the last-resort antibiotic vancomycin.

  @article{ , abstract = {Heteroatom-doped single-atom nanozymes (SAEs) hold great promise as enzyme mimics, yet their catalytic mechanisms remain unclear. This study reveals that the proton driving mechanism induced by sulfur doping in single-atom FeN 2 O 2 carbon dots (S-FeCDs) significantly enhances peroxidase (POD)-like activity. Synthesized via low-temperature carbonization, S-FeCDs exhibit FeN 2 O 2 coordination with sulfur in the second shell, as confirmed by XAFS and AC-STEM. The POD-specific activity of S-FeCDs reached 295 U mg −1 , which is 11.2-fold higher than that of sulfur-free FeCDs, with natural enzyme-like kinetics. In situ experiments, kinetic and mechanistic studies revealed that sulfur doping promotes H 2 O dissociation, enhances H + adsorption, reduces the Δ G for H 2 O 2 -to-·OH conversion. DFT revealed a lowered energy barrier for the rate-determining step (2*OH → *O + *H 2 O) from 2.50 to 1.62 eV. In vivo, S-FeCDs demonstrated broad pH efficacy in MRSA-infected wound models, achieving near-complete healing within 7 days.

In this study, we synthesized nitrobenzene-functionalized Au 6 Cu 2 (NO 2 -Au 6 Cu 2 ) clusters, integrating metal clusters with chemical radiosensitizers. The ligand 4-nitrophenylacetylene's hypoxia-selective toxicity arises from reductase-mediated radical generation under hypoxia, depleting GSH and compromising radiotherapy ROS clearance.

A primary challenge in industrializing CO 2 RR technologies for producing liquid fuel is the mass transfer limitation of CO 2 , which significantly reduces the current density of CO 2 RR. This study proposes a new enzyme-enhanced electrocatalysis platform for boosting CO 2 RR current density. This platform integrates an enzyme of bovine carbonic anhydrase (bCA), stabilized on carbon nanotubes (bCA@CNT), into formate/formic acid selective metal catalysts such as tin (Sn) and bismuth (Bi) to prepare Metal-bCA (M-bCA) hybrid cathodes. The incorporation of bCA enhances both the CO 2 hydration and the reversible dehydration of bicarbonate to CO 2 in the cathode. This dynamic catalysis of bCA facilitates rapid local regeneration of dissolved CO 2 from bicarbonate at the catalyst surface, thereby boosting the current density of CO 2 RR. Consequently, the formate current density of the Sn-bCA cathode was 3.3 times higher than that of the bare Sn cathode in a membrane-electrode assembly (MEA)-type cell.

It is desirable to develop TTA-UC materials of TTA emitters with large TTA rate constants ( k TTA ). However, molecular design to accelerate the bimolecular rate constant of k TTA has not been considered. We present a strategy to manipulate k TTA by assembling multiple chromophores linked to a boron in a rotationally symmetric manner, causing asymmetric motions by a localized triplet exciton. We have studied tri(9-anthryl)borane, which consists of three anthracenes linked via boron, as a TTA emitter. Time-resolved luminescence measurements confirmed that k TTA is improved compared to the conventional TTA-UC system using DPA, an anthracene-based monomer. Time-resolved electron paramagnetic resonance measurements showed that the improvement in k TTA is due to fast intramolecular triplet exciton hopping coupled with vibrational motions in the trimer molecule, which extends the reactivity at the collision distance between the excitons through the pseudo-rotational motions.

However, degradation of traditional electrolytes restricts high cut-off voltage < 4.4 V, while low lithium transference numbers ( t Li + ) lead to polarization and early charge/discharge termination, which typically necessitate use of multiple solvents or salt-concentrated electrolytes to enable high-voltage chemistry. To address this challenge, we developed a single-solvent, single-salt electrolyte with tris(2,2,2-trifluoroethyl)phosphate (TFEP), achieving a high t Li + of 0.78 and enabling ultra-high-voltage LMB operation up to 5.0 V. Large molecular sterics and electron density delocalization of TFEP enabled dominant presence of local aggregates (AGGs), which further populated to form large and ion-rich weakly-solvating nanometric aggregates ( n -AGGs), changing redox properties and promoting the interfacial stabilities to a greater extent. As a result, we showed suppressed dendrite formation with stable cycling for over 1500 h, and full-cell operations paired with LiNi 0.8 Mn 0.1 Co 0.1 O 2 (NCM811) at 4.7 V and with LiNi 0.5 Mn 1.5 O 4 (LNMO) at 5.0 V.

  @article{ , abstract = {Electrolytes play a crucial role in regulating interfacial chemistry, which is essential for the development of high-energy-density lithium metal batteries. Herein, we present an ether-based electrolyte system incorporating the simplest Grignard reagent, CH 3 MgCl, as an additive. This additive, endowed with Lewis-base characteristics, enhances the stability of the anode-electrolyte interface through bifunctional effects. During Li deposition, CH 3 Mg + preferentially adsorbs onto the electrode surface, attracting more anions into the Helmholtz layer. Concurrently, CH 3 − creates an electron-rich environment, facilitating nucleophilic attacks on anions and promoting its reduction to form an inorganic-rich solid-electrolyte interphase (SEI). Additionally, Mg 2+ undergoes electrodeposition prior to Li + , forming a Li-Mg alloy with subsequently deposited Li. This process lowers the nucleation barrier for Li deposition, resulting in improved deposition uniformity. Accordingly, the designed electrolyte demonstrates excellent cycling stability for Li anodes in both Li||Cu half-cells and full-cells paired with LiFePO 4 cathodes. Notably, Li||LiFePO 4 batteries using a thin-film Li anode pre-deposited on Cu retain ∼92.84% of their initial capacity after 300 cycles with an average Coulombic efficiency of ∼99.74%.

However, most XL-MS methods face significant sample loss during enrichment, limiting their applications to limited-quantity samples, and suffer from poor reproducibility (20%–40%), hindering precise quantification. To overcome these challenges, we developed a novel membrane-permeable cross-linker, 2,6-dimethylpiperidine disuccinimidyl tridecanoate (DPST), in which the dimethylpiperidinyl group enables one-step enrichment of cross-linked peptides via tandem mass tags (TMTs) antibody approach, eliminating sample loss from multi-step processes and allowing analysis from as few as 1E4 cells. DPST also allows the light and heavy isotopic labeling of cross-linked samples at the cellular level, which reduces inaccuracies from multi-step preparations. This generates reporter ions for precise MS2 quantification, improving the signal-to-noise ratio without increasing spectral complexity. Using DPST, we analyzed cross-links in primary neurons from single fetal mice and quantified the transient and weak interactions in dynamic liquid–liquid phase separation (LLPS) environments. Additionally, DPST's design supports multiple isotopic labeling configurations (e.g., 6-plex, 10-plex).

In going from 1 to 4 , by remote site substitution, there is systematic stabilization of LUMO energy, which correlates linearly with the increased OAT to PPh 3 resulting in 130 times reactivity enhancement for 4 compared to 1 . This kind of significant reactivity enhancement by tuning LUMO energy from remote site is very rare. Mechanistic study involving experimental and computational study reveals asynchronous mechanism that was hitherto not reported for any OAT. The observed increase in OAT reactivity from 1 to 4 is attributed to an increase in the extent of asynchronicity in corresponding transition states, which was controlled from remote site modification.}, archive = {J_ANGEW}, author = {Jyoti Devi and Anannya Saha and Suman K.

Although copper-based catalysts exhibit satisfactory adsorption energy for *C 1 species, the symmetrical charge distribution at adjacent copper sites leads to a strong repulsive force between adsorbed *C 1 . Herein, asymmetric copper-copper (Cu F -Cu N ) motifs with distinct adsorption behaviors have been constructed on the F-Cu 3 N substrate using the in situ isostructural substitution method. Compared to the high hybridization of Cu N 3d and N 2p orbitals, implanted F not only reduces the hybridization strength but also endows the Cu F with delocalized unpaired electrons. Accordingly, Cu F , beyond forming an isolated 3d z 2 -2p z σ bond between Cu and the key *C 1 intermediate (*CHO), offers additional 3d xz -2p z π back bonding to the *CHO. With dipole interactions in the asymmetric Cu F -Cu N motifs, the electrostatic repulsion between adjacent *CHO is diminished, efficiently promoting the C-C coupling in CO 2 RR. Therefore, the Cu F -Cu N motifs achieve an exceptional C 2 selectivity of 81.5% with a partial current density of −325.9 mA cm −2 and a C 2 /C 1 selectivity ratio of 10.47.

Fourier-transform infrared spectroscopy and continuous-wave electron paramagnetic resonance spectroscopy both reveal that this arises from the formation of paramagnetic polarons. We achieve maximal conductivities when 2DPs comprised of electron-rich nodes and electron-rich linkers are combined, which is a consequence of more delocalized polarons as unveiled by diffuse-reflectance UV–vis-NIR spectroscopy. Variable-temperature electrical conductivity measurements reveal two distinct Arrhenius regimes in all 2DPs investigated, which we attribute to the different thermally activated processes inherent to in-plane and cross-plane electronic transport in stacked 2DP multilayers.

The calculations of bond valence sum and energy distribution reveal that NFPP-holes possesses broad Na + transport path with reduced transport barrier (from 0.512 to 0.428 eV), improving Na + extraction efficiency. Additionally, photogenerated holes could regulate surface charge distribution on NFPP and thus form a film-forming agent fluoroethylene carbonate (FEC)-dominated electric double layer. Finally, it converts to a thinner (9.75 nm illumination) NaF-rich cathode interphase layer, avoiding subsequent excessive electrolyte decomposition. As a result, the NFPP under illumination delivers high capacity of 119.1 mAh g −1 at 1 C, showing 41.11% improvement compared to dark conditions.}, archive = {J_ANGEW}, author = {Mingrui Yang and Denghui Wang and Yunhua Ling and Longfei Wen and Xiaoniu Guo and Jiyu Zhang and Jiacheng Chen and Wenbin Li and Lingfei Zhao and Shunfang Li and Zhiguo Zhang and Weihua Chen}, doi = {10.1002/anie.202422732}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {30}, pages = {e202422732}, shortjournal = {Angew.

Under 65 °C and 12 kPa operation pressure, the TGTf membrane maintained a high water flux of 195 L m −2 h −1 and a salt rejection of 99.80% over 168 h of MD operation, which is the longest operation time ever reported for MD using COF membranes. In addition, the TGTf membrane showed unparalleled resistance to scaling and organic fouling, demonstrating great potential for real-world brine treatment. Experimental and simulation studies revealed that incorporation of fluorine atom not only enhanced the hydrophobicity of the COF membrane, but also created electrostatic barriers within the fluorinated nanochannels, efficiently preventing ion penetration. These results underscore the remarkable potential of fluorinated COF membranes in MD, offering a promising solution for sustainable brine desalination.}, archive = {J_ANGEW}, author = {Shuai Wang and Lishuang Gui and Di Qiao and Meiling Tao and Shilin Huang and Xuelin Tian}, doi = {10.1002/anie.202507913}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {29}, pages = {e202507913}, shortjournal = {Angew.

Here, we present a green electrocatalytic strategy for the first time that converts oximes to hydroxylamines over CuS. Specially, N -benzylhydroxylamine was achieved with 95% conversion and 80% selectivity from benzaldoxime at −0.9 V versus reversible hydrogen electrode. Mechanistic investigations reveal that CuS can optimize the adsorption energy of the reaction intermediates, making the N─O bond more difficult to cleave during the electrocatalytic hydrogenation, thus leading to a high selectivity formation of hydroxylamines.

Under low-dose US, IR&ZnPc@LNP-NO reduces in size (from ∼120  to ∼40 nm), enhancing tumor penetration, and releases NO to remodel the TME by normalizing vasculature and degrading ECM.

High-dose US irradiation triggers the generation of cytotoxic ROS, which, in combination with IR-mediated chemotherapy, induces immunogenic cell death (ICD) and enhances antitumor immunity. Additionally, combining IR&ZnPc@LNP-NO with PD-L1 antibody (αPD-L1) immunotherapy significantly prolongs survival in orthotopic PC models.

Characterized by atomically precise compositions and well-defined structures, the PCCs enable strategic manipulation of functionalized moieties and metal centers, allowing for precise control over their sonodynamic efficiency. Their small particle size enhances penetration through dense tumor extracellular matrices, significantly improving tumor permeability. Upon ultrasound stimulation, the PCCs exhibit robust sonodynamic effects, resulting in increased reactive oxygen species (ROS) levels in tumor cells, which triggers apoptosis and antigens release.

In this study, we demonstrate that a subtle variation of the linker enables interconversion between these two conformations, the in conformer being thermodynamically the most stable in water. At basic pH (>8) the out conformer is instantly converted into the in . In contrast, at acidic pH (<2), the out monomer can be kinetically trapped and can self-assemble into a supramolecular polymer.

Notably, the monoclinic α-(BuPh 3 P) 2 Cu 2 I 4 and β-(BuPh 3 P) 2 Cu 2 I 4 , both belonging to the P 2 1 / n space group, exhibit bright blue and orange emission, respectively. The orthorhombic-phase γ-(BuPh 3 P) 2 Cu 2 I 4 with space group Pbca and larger lattice volume shows vivid red emission, thus achieving tunable full-color emission wavelength spanning from blue (445 nm) to red (667 nm), representing the first instance of such broad tunability through adjusting the spatial arrangement of the organic and inorganic parts. Interestingly, α-(BuPh 3 P) 2 Cu 2 I 4 undergoes a reversible photo-induced fluorochromism, transitioning from blue to green. Furthermore, a reversible phase transformation between α- and β-(BuPh 3 P) 2 Cu 2 I 4 can be triggered by dichloromethane and ethyl acetate. As such, a photo-responsive switchable system and a multistage information encryption/decryption system are successfully devised through leveraging unique multi-stimuli-responsive properties.}, archive = {J_ANGEW}, author = {Jiajing Wu and Qiao-Feng Huang and Yi-Fan Fu and Jing-Li Qi and Li-Xiang Chen and Shu-Fang Yan and Wenlong Liu and Sheng-Ping Guo}, doi = {10.1002/anie.202506748}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {29}, pages = {e202506748}, shortjournal = {Angew.

Current protocols for the analysis of single sEV rely mainly on the advanced techniques and require lengthy isolation procedures, limiting applications in clinical diagnosis. Herein, we developed a one-step procedure for rapid isolation of single sEVs from urine, along with an analytical pipeline for the diagnosis of early bladder cancer (BCa). Single sEVs are isolated by an EV-imprinted gold nanohole (EI-AuNH) array that selectively traps individual sEVs and spatially enhances their Raman spectra. After the invalid spectral data from incomplete or absent sEVs was eliminated using Smart-Filter, a convolutional neural network model identifies the origin of the spectra and generates a digital count matrix for each patient. By integrating the digital count data of both tumor-associated and normal sEVs, our model achieves an accuracy of 97.37% in early diagnosis of BCa. Feature extraction using explainable AI identified nine BCa-related signatures, with noticeable reduction on cholesterol and lipids in BCa-associated sEVs. These signatures could further distinguish BCa from other cancers.

LCEs incorporating dynamic covalent bonds (DCBs) endowing network with rearranging ability through reversible bond exchange, facilitating the fabrication of soft actuators with tailored actuation modes and reprogrammability. However, unintended activation of DCBs during actuation, particularly under thermal perturbations, remains a critical challenge, as it damages actuation stability which arises catastrophic failure and potential security risks in practical applications. Present strategies in enhancing actuation stability either achieve only transient stability or sacrificed reprogrammability or actuation performance. Here, we propose a strategy incorporating catalyst-free α-AC/A DCB of high temperature active-threshold to fabricate stable exchangeable LCE actuators with thermally gated behavior. This design exhibits a “thermal gate” at 120 °C with inert bond exchange below this threshold, yet rapidly activated at 160 °C.

Consequently, it is still highly urgent for developing environment-friendly and effective artificial preparation methods for artemisinin.

  @article{ , abstract = {Quasi-two-dimensional (quasi-2D) perovskites have shown great potential in the application of light-emitting diodes (LEDs) due to their large exciton binding energy, tunable bandgaps, and solution processability. However, the heavily used spacer cations will cause serious deprotonation reactions in quasi-2D perovskite films, leading to lattice collapse and abundant defect states, which are notorious for fabricating efficient perovskite LEDs (PeLEDs). Herein, we develop an in situ proton-feeding strategy to restrain the deprotonation process in quasi-2D perovskites by introducing a proton-rich Lewis base, namely trifluoromethyl nicotinic acid (TFNA), into the perovskite precursor solutions. The TFNA molecules can donate protons during the growth of quasi-2D perovskite films to simultaneously compensate the deprotonated spacer cations, passivate the defects states by coordinating with Pb 2+ , and improve structural stability by forming hydrogen bonds with organic spacers.

The highest-ranked variant, psA121, shows a 3-fold increase in relative activity over the wild type at 0 °C.

Here, we report a novel host–guest interaction between one tetraurea macrocycle and two organophosphate anions with high affinity (association constant K a = 1.06 × 10 9 M −2 ). It can serve as noncovalent joints to efficiently link low-molecular-mass polyethylene oxide (PEO) diorganophosphates into long linear SPs.

As a result, the SP layer homogenizes Li + flux to achieve uniform Li deposition and significantly improves the electrochemical performance of LiFePO 4 full batteries by a factor of 285% with cycling stability over 200 cycles.

Notably, PSC performance exhibits a consistent enhancement with increasing rotational flexibility of the ammonium groups. Detailed carrier dynamics analysis reveals a direct correlation between molecular conformational freedom and defect passivation effectiveness. Theoretical calculations demonstrate that both static geometric matching and dynamic conformation adaptability to perovskite lattice defects govern the passivation quality.

However, synthesizing π-extended azulenes requires harsh reaction conditions, making it hard to achieve both functionalization and π-extension. Here, we report the synthesis of electron-deficient azulene-embedded polycyclic aromatic hydrocarbons (PAHs) with two alkoxycarbonyl groups by the rhodium-catalyzed intermolecular arylative [2 + 2 + 1] annulation of teraryl diynes with dialkyl acetylenedicarboxylates followed by oxidation at room temperature. Interestingly, for the electron-rich diyne, prolonged oxidation time after the arylative [2 + 2 + 1] annulation yields a helicene-like bis(azulene-embedded PAH) in good yield. Thus, obtained electron-deficient fused azulenes have small HOMO–LUMO energy gaps (up to E g elec = 1.52 and E g theo = 2.06), resulting in long-wavelength absorption extending into the near-infrared region.

According to electric double layer (EDL) theory, the potential difference in the Helmholtz layer critically affects electrochemical reactions at the electrode/electrolyte interfaces, which governs the solid electrolyte interphase (SEI) composition and the Na deposition process. Herein, we leverage the electric dipole effect of polymers, formed via in situ polymerization of butyl acrylate (BA), which preferentially adsorbs on the Na metal surface, to modulate the conformation of the EDL. Molecular dynamics simulations reveal that poly-BA facilitates the formation of a more compressed diffuse layer and reduces the potential difference in the Helmholtz layer. This compressed EDL with the change of species derives homogeneous SEI, enabling reversible Na plating/stripping.

Unfortunately, phosphorescence of the introduced RTP chromophores can easily be quenched in water-swollen hydrogel networks, limiting their luminescence performance and application adaptability. Herein, we propose a supramolecular confinement-entanglement synergy strategy to produce ultrastretchable RTP hydrogels by in-situ polymerizing high-concentration 2-(acryloyloxy)ethyl trimethylammonium chloride (AETC) in the presence of preassembled 4-biphenylboronic acid@β-cyclodextrin (4-BB@β-CD) emissive aggregates. The hyper-entangled poly(AETC) (PAETC) chains, formed under water-limiting conditions, synergistically densify the 4-BB@β-CD aggregates through supramolecular confinement, effectively suppressing molecular vibrations and stabilizing triplet states. Impressively, the hydrogels exhibit intense afterglow and ultralong phosphorescence lifetime up to 1.1 s under room conditions. Crucially, the entanglement-dominated physical network free of static chemical crosslinking enables continuing chain disentanglement during stretching for efficient energy dissipation. Segment length between physical entanglement points can thus be significantly enlarged to reduce network fracture and avoid crack propagation, achieving record-breaking uniaxial/biaxial (21 000%/10 000%) stretchability. Even the notched hydrogels are capable of being unprecedentedly stretched to 20 500% and exhibit a fracture energy as high as 157 kJ m⁻ 2 , demonstrating intrinsic crack-tolerance.

This small structural change gives rise to an enlarged interior cavity volume for guest encapsulation, as compared with a previously-reported trigonal prismatic capsule, where the same rectangular ligand took a “portrait” orientation with a non-methylated triangular ligand of similar size. The methylated triangular ligand contains a boron core, which can bind fluoride ions that point inward.

Thereinto, large tetrapropylammonium cations (TPA + ) surround [MnBr 4 ] 2− units, forming a zero-dimensional (0D) molecular confinement structure that promotes electron localization and achieves a notable light yield of 56800 photons MeV −1 . Meanwhile, the low dielectric constant of TPA + can enhance dielectric confinement of [MnBr 4 ] 2− units, mitigating exciton capture by deep defects. These synergistic effects in the scintillators lead to a large exciton binding energy of 1028.8 meV and an ultrafast response time of 500 fs.

To address this long-standing and inevitable obstacle, we proposed a new sensor design strategy, a dual-interface nanopipette sensor (DINS), to shield against the interferent electrochemically. The DINS comprised an anti-interference interface at the orifice of the nanopipette, and a sensing interface located at the inner wall with a certain distance from the orifice. Anti-interference interface, functioning as an “electrochemical Faraday cage”, electrochemically eliminated the interferents with high efficiency while allowed the target species to pass through and be detected at the sensing interface. With the synergy of these two independent interfaces, the GOD-modified DINS (GOD-DINS) allowed the accurate detection of intracellular glucose with effectively eliminating endogenous H 2 O 2 , facilitating the quantitative study on the glucose metabolism inside single cells.

  @article{ , abstract = {Thrombosis is a pathological condition which represents the formation of clots inside blood vessels, blocking the flow of blood through the circulatory system. A high occurrence of thrombotic events, particularly deep vein thrombosis and pulmonary embolism, has been observed in COVID-19 patients. Platelets (thrombocytes), the small cell fragments in the blood, play crucial roles in vascular haemostasis and thrombosis. The activation and subsequent aggregation of platelets lead to the formation of thrombus, a key process in the development of cardiovascular diseases. Therefore, inhibitors of platelet aggregation are important for the prevention and treatment of many thrombotic disorders. As the selenoenzyme glutathione peroxidase (GPx) is known to prevent platelet-dependent thrombosis, we have studied a series of antioxidant nanozymes for their ability to inhibit platelet activation/aggregation. Herein, we show that V 2 O 5 nanozymes with specific and morphology-dependent GPx activity effectively inhibit the aggregation of human platelets and prevent pulmonary thromboembolism in mice. Crucially, the nanozymes do not lead to the unwanted side effect of bleeding, which is important in the development of more effective and safe antithrombotic agents.}, archive = {J_ANGEW}, author = {G.

  @article{ , abstract = {Aqueous Zn-ion batteries (AZIBs) are promising for large-scale energy storage, yet Zn metal anodes face issues like hydrogen evolution, dendrite growth, and corrosion. Herein, we develop a self-healable, adhesive polymer layer for AZIBs by polymerizing thioctic acid (TA) on Zn surfaces. Thanks to the strong and spontaneous affinity between Zn metal surface and S atoms on polymer chains, this protective layer can firmly and dynamically adhere to the Zn surface. Thus, even at a thickness of <1 µm, the protective layer exhibits a strong adhesion force of up to 10.5 N with Zn surface, while the abundant carboxyl groups in the protective layer can form intramolecular hydrogen bonds, endowing its high self-healing property and enhancing its strength (Young's modulus reaches 15.1 GPa). Such a protective layer effectively inhibits the dendrite growth physically and regulates the Zn 2+ migration and deposition behavior chemically. Therefore, the symmetric cells can be cycled for more than 1000 h at the current densities of 1.0 and 5.0 mA cm −2 , respectively.

We propose that the initial metal-to-ligand charge transfer in Ce-Naph MOF, promoted by light, is essential for forming an active alkoxy-Ce(IV)-species. This species subsequently undergoes ligand-to-metal charge transfer to generate the alkoxy radical, which acts as a hydrogen atom transfer reagent to activate alkanes. Furthermore, Ce-Naph MOF demonstrated long-term cyclic stability, maintaining its catalytic activity and structural integrity over five cycles, highlighting its durability as a heterogeneous catalyst.

  @article{ , abstract = {Solvating power, a pivotal determinant of solvation structure, has been extensively studied in past few decades. However, extant descriptors such as donor number and binding energy, predominantly focus on solvation enthalpy, while ignoring crucial solvation entropy, which often leads to contradictory conclusions. Here, we surmount this issue by exploring the relationship between the solvation thermodynamics and solvating power. It is revealed that high solvation entropy of polydentate solvents (DME, DGDME, etc.) endows them with strong solvating power in spite of their low binding energy.

  @article{ , abstract = {Rechargeable zinc metal batteries (RZMBs) are promising for energy storage due to their high capacity and cost-effectiveness. However, their commercialization is hindered by challenges including dendrite growth, parasitic reactions, and cathode degradation, particularly under low current densities and negative/positive (N/P) capacity ratios. Localized high-concentration electrolytes offer potential solutions, but their reliance on high salt concentrations to replicate solvation structures of high-concentration electrolytes limits their practicality, due to diluent's inherent inertness that limits its role in interfacial chemistry. Here, we present a co-regulation strategy that integrates bulk and interfacial properties to develop an interfacial-enhanced localized high-concentration electrolyte (ILHCE). By incorporating non-coordinating 1,4-dioxane diluent and 1-ethyl-3-methylimidazolium (emim + ) cations into dilute aqueous electrolytes, dioxane molecules are pulled into electric double layer (EDL) through the interaction between emim + and dioxane, achieving a pronounced dilution effect from bulk electrolyte to the EDL. This generates an anion-rich and water-depleted EDL at both anode and cathode interfaces, enhancing Zn 2+ transport dynamics, ensuring cathode stability and deriving a robust anion-derived solid-electrolyte interphase. Full batteries using Mn 0.5 V 6 O 13 cathodes with a low N/P ratio of 1.77 demonstrate 80% capacity retention over 300 cycles at 0.2 A g −1 , highlighting ILHCE as a transformative electrolyte design toward real-world applications.}, archive = {J_ANGEW}, author = {Tao Li and Hange Yang and Xinji Dong and Hexian Ma and Jinghua Cai and Chenyu Wei and Tao Zhang and Shicong Zhang and Fuqiang Huang and Tianquan Lin}, doi = {10.1002/anie.202501183}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {29}, pages = {e202501183}, shortjournal = {Angew.

H3 efficiently transports protons while rejecting other ions and water molecules by forming multiple hydrogen bonding chains like natural proton channels. Patch clamp experiments revealed that H3 facilitates rapid proton transport ( γ H+ = 181 ± 4 pS) comparable to that of natural gramicidin A ( γ H+ = 213 ± 4 pS) and demonstrates high H + -selectivity, with P H+ / P K+ , P H+ / P Na+ , and P H+ / P Cl- values reaching 78.4, 233.2, and 167.8, respectively. H3 -induced proton transport causes elevated lysosomal pH and mitochondrial damage, ultimately resulting in severe cancer cell apoptosis (IC 50 : 0.23 µM for U87MG; 1.04 µM for B16F10).

Although ultrasound has been employed to remotely regulate biological functions by targeting mechanosensitive ion channels, existing systems are constrained by the limited responsiveness of specific channels to specific ultrasound frequencies and their applicability to only a few cell types.

Here, we introduce a new modular toolkit for regulating gene expression using ultrasound-responsive RNA carriers capable of releasing small molecule modulators in response to a broad spectrum of ultrasound frequencies. The cells contain engineered mRNA structures encoding riboswitches or aptazymes, which respond specifically to these small molecule modulators finally controlling downstream protein expression by biocompatible ultrasound. This toolkit is versatile, functioning across various eukaryotic systems—from yeast to mammalian cells—and offers control over gene expression by regulating mRNA translation. We demonstrated that this sonogenetic toolkit robustly modulates gene expression, achieving up to a six-fold downregulation of protein levels in response to ultrasound stimulation.

  @article{ , abstract = {Cisplatin (CP) is a first-line platinum-based drug used for the treatment of head and neck cancer. However, tumor cells can diminish the therapeutic effects of CP through the detoxification system mediated by glutathione (GSH) and the nucleotide excision repair (NER) pathway. Herein, we present a light-activable and pH-responsive oxidative stress nanoamplifier (FPLC@IR OSNA), comprising an amphiphilic compound (FPLC) with Fmoc-lysine acting as a connector between a nitroimidazole derivative and a pH-responsive cinnamaldehyde (CA) derivative, loaded with photosensitizer IR780. The acidic microenvironment of the lysosome can trigger the release of CA to produce H 2 O 2 , which breaks down into oxygen, further improving the phototherapy efficacy mediated by IR780 irradiation. The consumption of oxygen during the phototherapy process induces hypoxia, prompting the reduction of nitroimidazole to aminoimidazole and leading to reduced GSH synthesis, enhancing tumor cell death induced by CP. Meanwhile, the accumulation of intracellular reactive oxygen species (ROS) during phototherapy attenuates the nuclear NER pathway, further augmenting the therapy effect of CP.

Using a one-pot protocol, we first form an electrophilic chloroborazole and then react it with an aryl lithium (ArLi). By selecting the appropriate ortho -substituent, we can guide the ArLi to add to the BN-core in a specific way, ultimately controlling the stereochemical outcome of the three-substitution reaction. Rationalization of the stereochemical model through computational analysis allowed us to show that when aryl lithium nucleophiles bearing rigid long-range ortho -substituents are used, i.e., stiff substituents.

Interestingly, by adjusting the added molar proportion of C[3]A, multi-color TADF property of GPs@C[3]A could also be easily tuned. Notably, when a 20% molar ratio of C[3]A was added, GP1@C[3]A exhibited white luminescence. Especially, by using the high selectivity of C[3]A toward benzene and its differential binding affinities for acceptor guests versus benzene, rapid detection of trace benzene vapor was achieved in few seconds with the naked eyes.

However, their highly polar nature makes them challenging to handle, purify, and characterize. Boronic esters help overcome these issues, and pinacol esters (Bpin) have become the dominant boronic acid surrogate in organic synthesis. Despite its popularity, Bpin is not without drawbacks. Its formation from pinacol is intrinsically reversible in the presence of water or alcohols, which may cause premature release leading to losses during reactions and purification. This reversibility complicates the hydrolytic regeneration of free boronic acids, which often requires additional steps to destroy the pinacol by-product. Although other boronyl protecting groups exist, their removal requires harsh pH conditions. To address these issues, we developed xanthopinacol boronates (Bxpin), a robust protecting group for boronic acids with excellent orthogonality in various chemical reactions and mild irreversible removal under catalyzed photoredox conditions. Xpin boronates can be obtained directly by irradiation of a mixture of free boronic acid and xanthone with UV light, causing an in situ dimerization of xanthone to the required xanthopinacol.

Herein, we report for the first time a photoredox/nickel dual-catalyzed enantioselective decarboxylative acylation of α-hydroxy acid derivatives and aliphatic carboxylic acids, enabling efficient access to enantioenriched α-oxygenated ketones. This method exhibits a broad substrate scope, good functional group tolerance, high chemoselectivity, and excellent enantioselectivity (up to 99% e.e.). The advantage of this reaction is that it eliminates the need for metal reductants and the use of precious metal photocatalysts and utilizes renewable feedstocks. The use of a coiled-tube continuous-flow photoreactor can shorten the illumination time by half and obtain results comparable to those of a batch reaction.

Temperature-dependent PL intensity and line-width analysis unfolded strong exciton-phonon coupling in NP sample. Synchrotron X-ray pair distribution function analysis determines the local Cu off-centering, which provides the required lattice anharmonicity and softness for intense STE in Cs 5 Cu 3 Cl 6 I 2 NPs. The existence of such soft lattice structure associated with low-energy phonons was verified by sound velocity, Raman spectroscopy and low-temperature heat capacity measurements. The fluorescence microscopy and super-resolution optical imaging were implemented at single-particle level which exhibited minimal temporal PL intermittency with reasonable photostability under high-intensity illumination.

Herein, we investigate how the shape of the host alters the emission behavior of boron difluoride hydrazone (BODIHY) ( G 1 ) dye encapsulated within two iso-stoichiometric water-soluble coordination cages: MC1 (double-square cage) and MC2 (octahedral cage). Encapsulation of G 1 within MC1 results in a highly emissive solution, whereas similar confinement in MC2 leads to a non-emissive host–guest solution. A similar trend was observed with different sets of iso-stoichiometric cages MC3 (double-square cage) and MC4 (octahedral cage). Using a combination of femtosecond transient absorption and time-resolved fluorescence spectroscopy, we observed that the disparity in fluorescence behavior of BODIHY is attributed to charge transfer interactions between the guest and ligand panels of cages.

Therefore, introducing impurities or structural defects into their matrices presents a major challenge, particularly in a spatially-controlled manner.

This is achieved by directly incorporating poly(glycerol monomethacrylate) 51 - block -poly(benzyl methacrylate) 100 [G 51 -B 100 ] diblock copolymer nanoparticles into growing Cu 2 O crystals, leading to the formation of G 51 -B 100 @Cu 2 O composite crystals with structural defects localized at the G 51 -B 100 /Cu 2 O interfaces. The spatial distribution of these defects can be systematically engineered, ranging from the surface region to the entire crystal.

Based on experiments on new nonchiral monomers, dimers, and polymers, we construct a statistical theory that shows why many complex meso-structures form in two stages: continuous equilibrium growth of nano-clusters in melt through strong interactions, causing the C p -maximum, followed by establishment of positional long-range order (LRO) through a weak first-order transition. We also show why many achiral compounds additionally form an intermediate chiral Iso* liquid through what we find is a second-order transition. We propose that the first process is equivalent to “supramolecular polymerization” in solutions, where the lack of intercluster interaction rules out LRO. Furthermore, we argue that separation into a broad and a sharp transition is universal in condensed matter where strong interactions by themselves cannot lead to LRO, either because the clusters are 1D or due to strong frustration. Clusters must first grow to critical size when, at T c , the combined weak interactions reach ∼k B T c , prompting LRO formation.

Herein, we report a solution-phase strategy for surface reconstruction and passivation of InSb CQDs using sulfur-based nucleophilic covalent ligands. We find that short-chain thiol molecules remove surface metal oxides through nucleophilic attack and enable robust passivation of In and Sb via strong covalent bonds, whereas metal sulfides are less effective at oxide removal and passivation.

  @article{ , abstract = {The interaction between the microtubule associated protein Tau and the tyrosine kinase Fyn is believed to play a pivotal role in the early stage of Alzheimer's disease. Previous studies have identified the SRC Homology 3 (SH3) domain of Fyn as the binding receptor of several proline-rich motifs in Tau. However, the role of each proline-rich motif and their interplay in molecular recognition are still unclear. In this work, we investigated the mechanism of Fyn-SH3 recognition by the multiple PxxP sites inserted within the full-length Tau protein by using nuclear magnetic resonance (NMR) spectroscopy combined with computational, calorimetric and in-cell FRET (Förster resonance energy transfer) methods. Both in vitro and in-cell experiments revealed no single binding site strictly necessary for the binding. Instead, Fyn-SH3 contacts full-length Tau on multiple hot spot regions, located over a distance of 85 residues, through global moderate-to-low affinity interactions. Beyond two principal regions containing classical PxxP motifs, we identified a novel non-canonical binding site at the beginning of the microtubule binding domain. Our study indicates that multiple binding sites in Tau are involved in the interaction, making Tau an adaptable recognition surface that can function when single consensus motifs are deleted.}, archive = {J_ANGEW}, author = {Roberto Tira and Giulia Leo and Laura Prandini and Carlo Giorgio Barracchia and Mariapina D'Onofrio and Luca Mollica and Stefano Capaldi and Michael Assfalg and Francesca Munari}, doi = {10.1002/anie.202504292}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {28}, pages = {e202504292}, shortjournal = {Angew.

By programming the rigidity and length of sparsely distributed DNA bonds on M-DNA surfaces, we achieved long-range ordered assembly of triangular M-DNA 1D single-channel superlattice (3.7 ± 1.2 µm) with a macroporous structure.

Furthermore, an ultrathin gold layer grown on the triangular M-DNA superlattice exhibited a ∼3.3-fold enhancement in electrocatalytic activity compared to non-assembled triangular M-DNA, attributed to the increased surface area and narrower bandgap.

This approach involves a one-pot condensation of - Phenacetin and its homologs with formaldehyde, yielding phenacetin[3]arenes ( Ph[3] s) in yields up to 25.9%. Ph[3] exhibits an unsymmetrical hourglass-shaped architecture, featuring an upper rim adorned with amide groups and a lower rim comprising an alkoxylbenzene cavity. This unique structure facilitates reversible equilibrium between conformers via benzene ring flipping, which simultaneously reverses the orientation of amide groups, establishing equilibrium between C 3 and F conformers. Increasing concentrations of organic ammonium guests lead to a transition from a predominantly 1:1 to 1:2 host–guest complexation. The estimated binding constants for the 1:1 complexes are in the order of 10 4 –10 5 M −1 , the overall binding constants for the 1:2 complexes are greater than 10 6 M −2 . This stepwise complexation triggers a conformational shift from the C 3 to F conformer, demonstrating intriguing allosteric behavior. Furthermore, interactions with chiral guests selectively influence the equilibrium of planar chiral conformers, generating chiroptical responses suitable for chirality sensing applications.

To address these limitations, alternative platforms such as nanoparticle-mediated protein degraders (NanoPDs) have gained attention. First reported 17 years ago, NanoPDs harness a diverse array of materials, degradation mechanisms, and linker chemistries to achieve protein clearance through novel pathways. Although promising, their clinical translation remains constrained by barriers such as lysosomal entrapment, protein corona formation, and biocompatibility concerns.

So far, Turing structures are constrained by the highly cross-linked and heterogeneous porosities, impeding them from the application of molecular separations requiring loose but regular pore structures. This work reports a covalent organic frameworks (COFs) membrane with nanoscale striped Turing structures for fast and precise molecular separations. Porous and hydrophilic modulation layers based on metal-polyphenol chemistry are constructed on polymeric substrates, which are capable of enhancing the uptake and controlled release of the activator of amines during synthesis. The appropriately reduced diffusion rate triggers the phenomenon of “local activation and lateral inhibition” arising from thermodynamic instability, creating Turing structures with externally striped and internally cavitated architectures. The Turing-type COF membranes exhibit a water permeance of 45.0 L m −2 h −1 bar −1 , which is approximately 13 times greater than the non-Turing membranes, and an ultrahigh selectivity of up to 638 for two model peptides. This work demonstrates the feasibility that Turing structures with ultra-permeable internal cavities can be created in COF membranes and underscores their superiority in molecular separations, including but not limited to high-value pharmaceuticals.}, archive = {J_ANGEW}, author = {Bingjie Gao and Youxin Gong and Zhe Zhang and Qinghua Liu and Congcong Yin and Mingjie Wei and Yong Wang}, doi = {10.1002/anie.202503090}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {28}, pages = {e202503090}, shortjournal = {Angew.

Recent developments in sustainable chemistry intend to align foam lifecycles toward circular economy principles and reduce their environmental impact.

The self-blowing mechanism originates from the in situ formation and release of the blowing agent via the polycondensation of an alkylester. This alkylester, composed of a benzoxazine matrix terminated with a β -hydroxylamine, undergoes in a cascade mechanism ring opening polymerization (ROP) and irreversible transesterification exchange, which in turn generates an alcohol gas.

  @article{ , abstract = {The development of chemoselective tools that can conjugate, modify, and decouple chemical groups from biomacromolecules has enabled the study of biological processes at increasing levels of fidelity. Until recently, these tools can either couple chemical entities to biomacromolecules or decouple them, but not both. A method that can perform these functions in distinct steps on demand would be highly useful. To that end, we devised a new-to-nature strategy by bringing together and modifying two biocompatible transformations. In this new strategy, ligation is accomplished via the photoclick reaction between an allenyl motif with 9,10-phenanthrenequinone which installs an allyl group at the site of conjugation. This allyl group can then be selectively utilized as a handle for phenolic release via Pd-mediated deallylation. As a proof of concept, we demonstrated its utility in the selective labeling and delabeling of model protein scaffolds and cellular matrix. This multifunctional method paves the way for a controllable “ligate and release” strategy that enables on-demand visualization of biological entities but with an in built release mechanism to restore their original state.}, archive = {J_ANGEW}, author = {Boon Shing Loh and Hanqing Pang and Soh Wah Yong and Cheng Weng and Wee Han Ang}, doi = {10.1002/anie.202425479}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {28}, pages = {e202425479}, shortjournal = {Angew.

  @article{ , abstract = {New compounds targeting human malaria parasites are critical for effective malaria control and elimination. Here, we pursued the imidazoquinolinone AZD0156 (MMV1580483), a human ataxia-telangiectasia mutated (ATM) kinase inhibitor that completed Phase I clinical trials as an anticancer agent. We validated its in vitro activity against the two main forms of the Plasmodium falciparum parasite in the human host, viz. the asexual blood (symptomatic) stage and sexual gametocyte (transmission) stage. Resistance selection, cross-resistance, biochemical, and conditional knockdown studies revealed that AZD0156 inhibits P. falciparum phosphatidylinositol 4-kinase type III beta ( Pf PI4Kβ), a clinically-validated target for the treatment of malaria. Metabolic perturbations, fixed-ratio isobolograms, killing kinetics and morphological evaluation correlated AZD0156 inhibition with other known PI4Kβ inhibitors. The compound showed favorable in vivo pharmacokinetic properties and 81% antimalarial efficacy (4 × 50 mg kg −1 ) in a P. berghei mouse malaria infection model. Importantly, a cleaner biochemical profile was measured against human kinases (MAP4K4, MINK1) implicated in embryofoetal developmental toxicity associated with the Pf PI4Kβ inhibitor MMV390048. This improved kinase selectivity profile and structural differentiation from other PI4Kβ inhibitors, together with its multistage antiplasmodial activity and favorable pharmacokinetic properties, makes AZD0156 an attractive candidate for target-based drug repositioning against malaria via a medicinal chemistry optimization approach.}, archive = {J_ANGEW}, author = {John G.

Previous studies have revealed that the cellular prion protein (PrP C ) is frequently overexpressed in melanoma, contributing to tumor progression. This study presents the first proof of concept evidence that nucleic acid aptamers can be used to construct a molecular tethering agent that regulates PrP C protein levels by inducing membrane-bound PrP C aggregation for antimelanoma therapy. Using a screening strategy combining cell-SELEX and cell-internalization SELEX, we obtained ssDNA aptamer, TT-1e, specifically binding to melanoma cells and tissues. We identified that the binding site of TT-1e is located at the octapeptide repeat region of glycosylated PrP C . Based on the binding characteristics of TT-1e, we engineered an aptamer-based molecular tethering agent TTe-TTe. We found that TTe-TTe induces aggregation of cell surface PrP C , promoting its internalization and facilitating its lysosomal degradation. This process resulted in the inhibition of AKT pathway activation. Importantly, in vivo studies confirmed the ability of TTe-TTe to target melanoma xenografts and suppress tumor growth through this unique mechanism.

  @article{ , abstract = {Lithium–sulfur batteries (LSBs) are considered promising next-generation batteries due to their high energy density (>500 W h kg −1 ). However, LSBs exhibit an unsatisfactory energy density (<400 W h kg −1 ) and cycle life (<300 cycles) because of the shuttle effect caused by soluble lithium polysulfide (LiPS) intermediates and the sluggish conversion reaction kinetics caused by insulating sulfur (S 8 ) and lithium sulfide (Li 2 S). Although various types of catalysts, including metal-based compounds to single-atom catalysts, have been reported to address these issues, most catalysts exhibited limited catalytic activity under practical lean electrolyte conditions (<5 µL mg −1 ). A comprehensive understanding of the synthetic strategy and catalytic mechanism of catalysts is essential for their design, but understanding the electronic effects of the catalysts and LiPS is more important. Furthermore, the electronic design of these catalysts is not well understood. In this review, we introduce the catalytic mechanisms in LSBs and discuss catalyst design strategies in terms of electronic effects on the interactions between reactants and catalysts, with a primary focus on heterogeneous catalytic systems.

Chemoproteomic experiments with P7, which utilizes 2-ethynylbenzaldehyde (EBA), identified 16 endogenous BRDs, thus giving a global landscape of ligandable lysines in BRDs.

An in-depth analysis of their distinct 15 N shielding tensors revealed that bent μ -nitrides invariably possess a high-lying proton-accepting molecular orbital (MO) and a low-lying electron-accepting MO. These electronic-structure features are key to the bent μ -nitrides affecting hydrogenolysis via either two-electron oxidation of H 2 or H 2 heterolysis.

The semihydrogenation allows the selective addition of H 2 to the less substituted and electron-rich alkyl-substituted C═C bonds of allenes while enabling the suppression of competitive over-hydrogenation, proving generally to form trisubstituted E -alkenes in high chemo-, regio-, and stereoselectivity.

Among nine prepared NHCs, YC-NHC8 is the optimal ligand for Cu(I)-catalyzed asymmetric S N 2′ silylation, YC-NHC3 works as the best ligand for Cu(I)-catalyzed enantioselective conjugate silylation of simple α,β-unsaturated amides, and YC-NHC9 serves as the most suitable ligand for copper(I)-catalyzed asymmetric silylation of azadienes. Remarkably, these three reactions are successfully run under a catalyst loading of 0.1 mol%, indicating that YC-NHCs may have the potential to be broadly used in efficient asymmetric transition metal catalysis.}, archive = {J_ANGEW}, author = {Zhen-Xi Cai and Qi Zhang and Tian-Yu Wei and Hu Tian and Jia-Wei Jiang and Zhang-Yi Wei and Liang Yin}, doi = {10.1002/anie.202508572}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {27}, pages = {e202508572}, shortjournal = {Angew.

This work revealed the anode failure mechanism, identifying a water-triggered degradation process, which depletes active lithium content, and developed an atmosphere-induced protective strategy. The degradation is triggered by trace water and sustained by the CO 2 component, which results in transforming active lithium into Li 2 CO 3 . Thus, a strategy was provided to respond to the water molecules brought by the semi-hermetic system and high charging voltage. The protective layer was in situ polymerized and can interact with water molecules, leading to further polymerization, thereby inhibiting side reactions, significantly extending the battery's lifespan.

This superior scintillation performance originates from an 86.3 ± 0.19% photoluminescence quantum yield, attributed to enhanced ligand-to-metal energy transfer efficiency and the suppression of π–π stacking among organic chromophore ligands. Besides, the fabrication of flexible Eu-O-Bphen films achieves a spatial resolution of 37.0 lp mm −1 in static imaging and enables real-time dynamic X-ray imaging at 60 fps (2 K).

Li⁺ hopping networks within the electrolyte can be preserved even at low temperatures due to the coordination of lithiophilic groups in HFME molecules with Li⁺. Simultaneously, lithiophobic group induced spatial confinement effects promote the formation of anion–cation aggregates (AGGs), significantly optimizing Li⁺ desolvation kinetics and boosting the formation of inorganic-dominated solid electrolyte interphase (SEI) with exceptional thermal stability.

  @article{ , abstract = {Separation of acetylene (C 2 H 2 ) from carbon dioxide (CO 2 ) remains a challenge to achieve both high C 2 H 2 uptake and selectivity for a single material. Porous materials with open metal sites (OMSs) have been widely employed to separate various gas mixtures; however, routine OMSs often show the limitation in C 2 H 2 /CO 2 separation due to the comparable binding affinity with the two gases. Herein, we report a new strategy of anchoring highly unsaturated nickel(II) sites into a large-pore MOF (Ni 2+ @NOTT-101-(COOH) 2 ) for simultaneously improving C 2 H 2 adsorption and selectivity. The coordination geometry of the anchored Ni 2+ ion was accurately determined by SCXRD studies, featuring a two-coordination model with highly unsaturated OMSs after the activation. This highly unsaturated Ni 2+ ion can provide additional binding sites to improve C 2 H 2 adsorption and also enable highly selective binding of C 2 H 2 over CO 2 through the specific and strong π- complexation interactions, as revealed by gas-loaded SCXRD studies and theoretical simulations.

Herein, we devise a “spin-selective electron donation” strategy to tune specific d orbital electrons of Pd inspired by the Dewar−Chatt−Duncanson model theory. Co−S−Pd bridges with different spin-states of Co III have been constructed in a series of Pd–PdS 2 –Co x HNSs with tunable Co content. Experiments and theoretical calculations indicate that low-spin Co III (t 2g 6 e g 0 ) with fully occupied t 2g orbitals and empty orbitals can accurately alter the electron of Pd by σ-donation via the Co−S−Pd bridge. In contrast, the unfilled d xy orbital of high-spin Co III (t 2g 5 e g 1 ) is essential for controlling the d xy electron of Pd via π-donation. Benefiting from state optimization by σ-donation, Pd–PdS 2 –Co 4.0 delivers superior performance toward various bio-alcohols (ethanol, ethylene glycol, and glycerol) with enhanced C─C bond cleavage. Furthermore, coupling the glycerol oxidation reaction with the CO 2 reduction reaction (GOR||CO 2 RR), the electricity consumption of GOR||CO 2 RR drops 46.4% compared to the state-of-art system (OER||CO 2 RR).

  @article{ , abstract = {Developing efficient Ru-based catalysts is crucial in reducing reliance on costly Ir for the acidic oxygen evolution reaction (OER). However, these Ru-based catalysts face a fundamental stability challenge due to the highly reactive nature of lattice oxygen.

This also surpasses the performances of most reported Ru-based catalysts. In contrast, doping with other elements from the same period, such as Mn, Co, or Cu, shows negligible improvements in catalytic performance. In situ electrochemical spectroscopic analysis, couples with theoretical calculations, reveals that the p–p orbital hybridization in the Ga–O coordination within Ga–RuO x effectively reduces the reactivity of lattice oxygen, suppresses the overoxidation of Ru, and switches the reaction pathway from the lattice oxygen mechanism to the adsorbate evolution mechanism.

Herein, efficient and durable CO 2 photoreduction is realized over a Ru NPs /Ru-PHI catalyst assembled by anchoring Ru single atoms (SAs) and nanoparticles (NPs) onto poly(heptazine imide) (PHI) via the in-plane Ru-N 4 coordination and interfacial Ru-N bonds, respectively. This catalyst shows an unsurpassed CO production (32.8 µmol h −1 ), a record-high apparent quantum efficiency (0.26%) beyond 800 nm, and the formation of the valuable H 2 O 2 . Ru SAs tune PHI's electronic structure to promote in-plane charge transfer to Ru NPs, forming a built-in electron field at the interface, which directs electron-hole separation and rushes excited electron movement from Ru-PHI to Ru NPs. Simultaneously, Ru SAs introduce an impurity level in PHI to endow long-wavelength photoabsorption, while Ru NPs strengthen CO 2 adsorption/activation and expedite CO desorption. These effects of Ru species together effectively ensure CO 2 -to-CO conversion. The CO 2 reduction on the catalyst is revealed to follow the pathway CO 2 → *CO 2 → *COOH→ *CO→ CO, based on the intermediates identified by in situ diffuse reflectance infrared Fourier transform spectroscopy and further supported by density functional theory calculations.}, archive = {J_ANGEW}, author = {Bo Su and Sibo Wang and Wandong Xing and Kunlong Liu and Sung-Fu Hung and Xiong Chen and Yuanxing Fang and Guigang Zhang and Huabin Zhang and Xinchen Wang}, doi = {10.1002/anie.202505453}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {27}, pages = {e202505453}, shortjournal = {Angew.

Herein, we presented a “polycondensation–depolymerization–repolymerization” strategy for structurally diverse aliphatic polycarbonates. This involved a step growth polycondensation of dialkyl carbonate and diol to low-molecular-weight (0.5−1.9 kDa) polycarbonates under atmosphere pressure, which are then utilized to produce cyclic carbonate monomers through catalytic depolymerization. The ring-opening polymerization of cyclic carbonate led to high molecular weight (>100 kDa) polymers, which can be converted back to cyclic monomer via ring-closing depolymerization or diol/dialkyl carbonate via alcoholysis, enabling chemical recycling of polycarbonates via dual closed loops. The thermal and mechanical properties of the polycarbonates can be widely adjusted by varying the substituent, and polycarbonate with four-membered spiro-cyclic substituent shows a recorded high melting temperature (217 °C) and mechanical strength within the reported polycarbonate family.

Herein, we present a new class of rare earth single-atomic hybrid glasses, synthesized via bottom-up self-assembly, as a solution to these limitations. By harnessing the ultralong phosphorescence of Nd 3+ -doped complex glasses, these materials achieve NIR-II emission extending to 1.32 µm with a photoluminescence quantum yield (PLQY) of ∼5.7%, setting a new record among state-of-the-art rare-earth-based complexes in the NIR-II region. This exceptional performance stems from the efficient sensitization of Nd 3+ ions in hybrid glass, with a phosphorescence energy transfer efficiency of 93.55%.

Here, we developed a novel metal-free heteronuclear diatomic-based catalyst that simultaneously addresses these challenges through atomic-level triple synergy engineering. Silicon–iodine dual-atoms are precisely anchored on nickel oxide ultrathin nanosheets supported on carbon cloth (Si/I-NiO@CC) via a gradient-heating co-loading method.

Advanced in situ spectroscopic characterization combined with electrochemical evaluation reveals the triple synergy mechanism: electron-deficient Ni δ⁺ and oxygen vacancies generate abundant active sites while mitigating HER competition, iodine-mediated proton reservoirs dynamically regulate H* coverage to maintain species balance, and covalent Si─O─Ni interfacial bonding inhibits metal leaching and stabilizes the catalytic system.

Specifically, the DMF-solvated framework SHF-62-DMF , in DMF as pressure-transmitting medium, undergoes initial hyperexpansion of pore cross-section ( p ≤ 0.9 GPa), due to DMF ingress, followed by reversal/reduction at p > 0.9 GPa while pore length contracts for all pressure increases, revealing decoupling of the two framework deformations.

Exposed carboxylates enhance semiconductor-water interfacial compatibility, reducing contact resistance and accelerating charge transfer kinetics. Furthermore, the carboxylate substitution shifts polarity centers, amplifying the molecular dipole moment by 10-fold. This induces a giant built-in electric field, enabling ultrafast electron-transfer process (ca. 0.31 ps) in the hPTB7-Th:PCBM bulk heterojunction. Consequently, the hPTB7-Th:PCBM-based bulk heterojunction nanoparticles exhibit excellent photocatalytic activity, achieving an optimal hydrogen evolution rate of 111.5 mmol g −1 h −1 , four times over the ester-based counterpart (PTB7-Th:PCBM). Moreover, the electrostatic stability imparted by the carboxylates endows hPTB7-Th:PCBM with outstanding operational stability, maintaining 81% of its initial hydrogen evolution rate after 100 h operation.

For P1 , these changes can be reversed by metal-mediated single-chain nanoparticle (SCNP) formation upon base addition, giving access to a stimuli-responsive polymeric photocatalyst.

  @article{ , abstract = {Nanoscale zero-valent iron (nFe 0 ) materials hold great promise in environmental remediation, yet achieving high reactivity, selectivity, and stability in reduction remains a long-standing challenge. Here we address this challenge by employing Ni lattice and FeS surface engineering to fabricate novel nFe 0 -based nanomaterials (dubbed as FeNi x @FeS y ), featuring FeNi as the core and FeS as the shell. The FeNi 5 @FeS 10 delivered approximately 242.7- and 81.2-times higher reactivity and selectivity, respectively, over unmodified nFe° for the remediation of trichloroethene (TCE; a notorious environmental pollutant), while maintaining high stability in groundwater remediation. We found that the core composition (i.e., Ni/Fe ratio) of FeNi x @FeS y primarily determined reactivity, governed by a tradeoff between the galvanic effect and lattice strain, while shell properties mainly controlled selectivity, despite some interactions between them. Density functional theory (DFT) calculations revealed that the FeS surface served as a favorable adsorption site for TCE, and the low energy barriers (TS2, 0.19 eV) of FeNi 5 @FeS 10 facilitated the cleavage of the first chlorine from TCE. Moreover, the core-shell structure promoted electron transfer from the core to the shell and TCE.

Our findings highlight the critical role of interactions within the first and second Zn 2+ solvation shells in determining electrochemical performance.

This approach prevents the formation of a passivation interphase layer on the electrode surface, which typically occurs with higher additive concentrations, leading to increased interphase resistance and cell polarization.

Under light irradiation, localized surface plasmon resonance (LSPR) excitation of 3D AuNPs can release huge plasmonic heat and produce abundant hot charge carriers (hot electrons and holes) simultaneously.

Instead, they are regarded as detrimental to such interactions due to the assumed charge repulsion between their deprotonated, negatively charged side chain carboxylate groups and the phosphodiester. Accordingly, acidic amino acids are often purposefully introduced into proteins to abrogate nucleic acid interactions in functional studies. Here, we show that in appropriate structural contexts, glutamate side chains are readily protonated even at neutral pH and act as hydrogen bond donors to phosphodiester groups using a c-di-GMP binding protein – the GSPII-B domain of PilF from Thermus thermophilus – as an example.

We demonstrate that this designed material composes a potent photoredox catalyst for efficient aryl cross-coupling, borylation, hydrogenation, as well as Birch-type dearomatization reactions, with good recyclability and stability. In particular, when exclusively using natural sunlight as an energy source, the product yield can still reach up to 90%. Our findings introduce a straightforward yet viable way to progress toward the century-long dream of leveraging natural sunlight to produce structurally complex organic molecules, just like plants on Earth.}, archive = {J_ANGEW}, author = {Yuemei Li and Shi-Yu Guo and Hongfei Gu and Bingyu Wang and Peiwu Su and Xiuming Zhang and Haoqing Zhang and Shuping Zhang and Fanzhi Yang and Jia Liu and Qing-An Chen and Jiatao Zhang}, doi = {10.1002/anie.202425601}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {27}, pages = {e202425601}, shortjournal = {Angew.

  @article{ , abstract = {Intrinsically disordered regions (IDRs) are ubiquitous in proteins, orchestrating complex cellular signaling through higher-order protein assemblies. However, the properties and functions of intrinsically disordered peptide (IDP) assemblies are largely underexplored. This work unveiled a facile strategy for engineering IDP assemblies. We demonstrate that conjugating a structured motif derived from a protein's phosphorylation site to a self-assembling tripeptide unexpectedly yields self-assembled nanofibers with intrinsic disorder. Specifically, by using a glycine linker to attach a pentapeptide derived from a phosphorylation site within a random coil region of SRC kinase to the C-terminus of a widely used self-assembling enabler, we generated a phosphorylated octapeptide. The octapeptide exhibits cell compatibility and forms a hydrogel upon dephosphorylation of the phosphooctapeptide. Cryo-electron microscopy (cryo-EM) structural analysis of the nanofibers reveals that the peptides adopt two types of helical arrangements but exhibit intrinsic disorder at the periphery of the nanofibers. The hydrogels exhibit decreased protein adsorption with increasing peptide concentration. This study represents the first instance of a structured random coil within a protein transitioning into an intrinsically disordered state within self-assembled peptide nanofibers, expanding the pool of peptide sequences for IDPs and providing valuable insights for the engineering of peptide nanofibers with intrinsic disorder for the development of cell-compatible biomaterials.}, archive = {J_ANGEW}, author = {Yuchen Qiao and Ayisha Zia and Adrianna Shy and Grace Wu and Matthew Chu and Zhiyu Liu and Fengbin Wang and Bing Xu}, doi = {10.1002/anie.202425456}, journal = {Angewandte Chemie International Edition}, month = {7}, number = {27}, pages = {e202425456}, shortjournal = {Angew.

Their photoinitiation efficiencies are systematically assessed under both visible-light LED and sunlight. Notably, the conversions reach up to 81% within just 30 s under sunlight, demonstrating the ultrafast and efficient polymerization capabilities of the dyes. The efficient electron transfer is facilitated by the D-π-A structure, where the conjugation is reduced or interrupted by the high distortion between the electron-withdrawing and the electron-releasing units. This distortion can prevent the overlap of frontier molecular orbitals, decreasing the energy difference between the ground state and the excited state of dyes, thereby enhancing the electron transfer reactivity with additives.

Through X-ray crystallographic studies and structure-activity relationship (SAR) studies, we identify key interactions that are essential for binding and activity. We find that the macrocyclic peptide CP-06 adopts a beta-hairpin structure and binds CD59 through an intermolecular beta-sheet, mimicking protein–protein interactions of biologically relevant CD59 interaction partners. We create dimeric and lipidated macrocyclic peptide conjugates as enhanced cell-active CD59 inhibitors and show that these probes can be used to modulate both complement-mediated killing of human cells and lytic activity of bacterial virulence factors.

However, such a mechanism requires pulsed laser excitation and cannot compete when a conventional one-photon excitation is also feasible with the selected excitation wavelength range. Using several spectroscopic techniques and reactivity assays under different light color and intensity conditions, we unambiguously demonstrate that a conventional one-photon excitation followed by rather inefficient singlet oxygen generation (quantum yield <5%) is responsible for the observed photoreactivity of the Cu(I) complex. In addition, we briefly summarize general mechanistic considerations, estimate typical photon densities required for a variety of two-photon mechanisms, highlight the importance of optical filters and impurities to avoid artifacts in the emission spectra, and present some guidelines for the differentiation between one- and two-photon mechanisms.}, archive = {J_ANGEW}, author = {Julian A.

We herein isolate two distinct thirteen-membered silver cluster isomers, Ag 13 -A and Ag 13 -M , in acetone and methanol, respectively. Significantly, we demonstrate the interconversion of these isomers facilitated by solvent manipulation. Mechanistic studies on the solvent-driven Ag 13 -A to Ag 13 -M transformation reveal this transformation proceeds with a low activation energy (23.39 ± 0.81 kcal mol −1 ) and positive entropy, involving counter anion dissociation, ligand twisting, and re-coordination. The observed differences in thermal stability and reactivity between two isomers are attributed to variations in Ag–Ag interactions and surface ligand arrangements, underscoring the critical role of solvent selection in affecting the whole organic transformation through in situ formed clusters.

Stoichiometric, catalytic, and mechanistic kinetic studies, supported by DFT calculations, reveal that bis-cyclometallated ruthenium species are key intermediates in these reactions. These studies also show that oxidative addition with bromoarenes proceeds via a concerted oxidative addition pathway, as demonstrated by DFT and experimental kinetic orders. Bromoarene activation does not proceed at mono-cyclometalated species. In the catalytic process, zero order kinetics are observed on both reaction substrates, an observation that is rationalized by DFT calculations which predict a rate-limiting step within the product-release stage.

In situ measurements uncover that the photo-generated holes counteract Cu 2+ electroreduction to retain the intact structure of CuInS 2 /CuS, while *OH dissociated from water can spontaneously anchor toward S V to hinder the local proton migration, completely circumventing multiproton products. Meanwhile, the preferential desorption of *CO from Cu centers adjacent to the *OH-anchored S V renders the exclusive formation of CO. In the absence of S V , *CO can be further hydrogenated in a lower free energy/even spontaneously to afford CH 4 .

  @article{ , abstract = {Electrocatalytic synthesis of cyclohexanone oxime from rich nitrogen resources is a promising alternative to traditional industrial processes. However, the difficulties in unraveling atomic-scale catalytic mechanisms and managing selective C─N coupling still pose great challenges to realizing considerable yield and selectivity, and therefore rational catalyst design to boost collaborative C─N coupling for oxime synthesis is particularly attractive. In the present work, molecular catalysts are demonstrated to be unique for oxime synthesis under mild conditions, i.e., iron bis(pyridyl)amine-bipyridine (FeBPAbipyH) modified MWCNTs@CP (multi-walled carbon nanotubes coated carbon fiber paper) cathodes produced cyclohexanone oxime from NO 2 − and cyclohexanone, attaining mass-specific efficiency of 87.00 mg h −1 cm −2 mg cat −1 , Faradaic efficiency (FE) of 77.3%, and exclusive carbon selectivity, which is the best efficiency known to date in H-cell.

Herein, we report asymmetric α-alkenylation of carbonyl compounds using potassium alkenyl trifluoroborate as a model reaction to demonstrate the capability of primary amine catalysis under electrochemical conditions. By employing enamine redox mediator mapping (e-RM 2 ) strategy, a new organic mediator, dimethoxyl naphthalene, was found to greatly enhance reactivity. Mechanistic studies uncover an ion-pair interaction between protonated aminocatalyst and anionic substrate that accounts for the exceptional enantioselectivity.

  @article{ , abstract = {Sunlight-driven production of high-value chemicals from renewable resources represents a pivotal driver toward achieving sustainable energy supply. However, fundamental barriers include inadequate use of light energy and insufficient understanding of reactive oxygen species (ROS) regulating mechanisms in photocatalytic processes. To address this, a novel symbiotic strategy for the design of Cu x /TiO 2 single-atom catalysts (SACs) supported by density functional theory (DFT) calculations was proposed. The developed catalyst achieved nearly 100% conversion and selectivity for the directional photooxidative transformation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) or 2,5-furandicarboxylic acid (FDCA) under both vis-light and UV–vis light conditions. Importantly, compared to previous works, this catalyst exhibited the highest photooxidation activity reported to date while effectively suppressing the over-oxidation of HMF to CO 2 . Mechanistic investigations revealed that rational construction of Cu single-atoms (SAs) could effectively create the asymmetric Cu–Ov–Ti structure, which significantly enhanced the activation of O 2 and HMF, facilitating generation of oxygen vacancy (Ov) and Ti 3+ . Furthermore, Cu SAs served as hole (h + ) extractors in the photooxidation process, promoting rapid charge carrier transfer and ROS formation. The applicability of this developed strategy was further demonstrated for photooxidative conversion of various bio-feedstocks, including HMF and alcoholic substrates, indicating its great potential for harnessing light energy for sustainable valorization of biomass into high-value chemicals.}, archive = {J_ANGEW}, author = {Qiong Yan and Yang Chen and Bing Tang and Xu Wu and Heng Zhou and Hao Wang and Hui Li and Lanlu Lu and Heng Zhang and Song Yang and Chunbao Xu and Tianyi Ma}, doi = {10.1002/anie.202505718}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {26}, pages = {e202505718}, shortjournal = {Angew.

Through systematic variations in stoichiometry and metal identity to the core-shell precursor NPs, along with atomistic simulations that probe phase stabilities, we deduce that the final mixing states of the various NPs are governed by the balance between the enthalpy and entropy of mixing. Moreover, our annealing method allows us to trap NPs at intermediate states of mixing, creating distinct surface ensembles that were evaluated as catalysts for the hydrogen evolution reaction.

Yet specific ion effect, which is known to possess potent effect on intermolecular interactions, has remained unexplored for such a purpose. Here, we demonstrate our access to dynamic self-assembly of supramolecular hydrogels by orchestrating the Hofmeister effect through a simple enzymatic reaction. The involved gelators containing carboxylate moieties self-assemble into hydrogel (Gel1) at acidic pH and dissolve at basic pH. We surprisingly find that the dissolved gelators at basic pH can be driven to self-assemble into hydrogel (Gel2) by kosmotropic ions through the disruption of gelator–water interactions. By coupling to the enzymatic hydrolysis of urea, Gel1 gradually disintegrates over time because of the production of basic NH 3 . However, interestingly, with the accumulation of kosmotropic ions, NH 4 + and CO 3 2− , the dissolved gelators are driven to self-assemble into Gel2, realizing a self-regulating gel–sol–gel transition process.

When sacrificial agent and photosensitizer were added to the CO 2 RR system, the maximum CO production rates for Mo 16 Cu 36 -1 and Mo 22 Cu 30 were 5672.1 µmol g −1 h −1 and 7370.8 µmol g −1 h −1 , respectively, with CO selectivities of 90.3% and 90.6%. The Mo─O─Cu active sites play a dual role in enhancing both CO 2 adsorption and activation, as well as facilitating charge separation.

By coordinating axial Cl atoms to iron phthalocyanine (FePc) molecules on carbon nanotubes (CNTs) matrix, a Cl-modulated Fe–N–C (FePc-Cl-CNTs) catalyst is synthesized. The as-prepared FePc-Cl-CNTs exhibit an improved ORR activity with a half-wave potential of 0.91 V versus RHE in alkaline solution, significantly outperforming the parent FePc-CNTs (0.88 V versus RHE). The advanced nature of the as-prepared FePc-Cl-CNTs is evidenced by a configured high-performance rechargeable Zn–air battery, which operates stably for over 150 h. The experiments and density functional theory calculations unveil that axial Cl atoms induce the transformation of FePc from its original D 4h to C 4v symmetry, effectively altering the electrons distribution around the Fe-center, by which it optimizes *OH desorption and subsequently boosts the reaction kinetics.

Structural characterizations reveal that the TiN support experiences severe leaching during OER test, leaving minor amounts of Ti–O species trapping on IrO x clusters, which mitigate the overoxidation of Ir(III) species and elongate the Ir–O bonds. This leads to 70% reduction of lattice oxygen oxidation and the substantially reduced Ir leaching.

Although this reaction occurs at higher potentials in basic electrolytes, it shifts to lower potentials in acidic environments due to the protonation and stabilization of pyri-N.

Over the past two decades, a number of seminal studies have significantly contributed to our understanding of natural product evolution.

By combining retro-evolutionary analysis with structure-guided genome mining, we could discover a potential evolutionary ancestor that links nostopeptolide and minutumamide biosynthesis. In addition, we were able to trace nostopeptolide-related module and domain blocks in various other biosynthetic pathways, indicating a surprisingly vivid mixing and matching of biosynthesis genes in the evolution of NRPS and cis -acyltransferase PKS/NRPS pathways, which was previously regarded as a unique feature of trans -acyltransferase ( trans -AT) PKS.

This study presents an intramolecular energy transfer (IMET) strategy to enhance these critical properties. We developed xanthene-based IMET cassettes by covalently linking donor and acceptor, achieving significant improvements in single-molecule imaging performance. While extensive spectral overlap is generally beneficial in bulk systems, single-molecule imaging necessitates careful optimization to minimize direct acceptor excitation at the high excitation powers typically used. Our optimized cassettes, featuring rhodamine as donor and Si-rhodamine as acceptor, exhibit 94.8% energy transfer efficiency. This configuration effectively minimizes direct excitation-induced acceptor bleaching, as 94.9% of molecules exhibit donor photobleaching prior to acceptor photobleaching. This efficient energy management leads to a 670% enhancement in photostability, arising from the competition between IMET and photobleaching pathways, which effectively channels excitation energy away from photo-destructive processes. Time-resolved transient absorption spectroscopy revealed that IMET occurs on a picosecond timescale, significantly faster than both fluorescence relaxation (nanoseconds) and photobleaching (seconds).

However, the subtle nature of these interactions poses challenges for characterization using standard techniques. Herein, an efficient method of weak binding characterization based on the zero-field splitting of a high-spin probe by electron paramagnetic resonance is presented. Using endofullerene as the high spin center, we achieved direct comparison of the weak binding strengths in F-MTPP (M = H 2 , Zn, Ni, and Pd) and 2F-3MTPP (M = H 2 , Ni, Pd, and Pt) through the zero-field splitting parameters. The high-spin resonance spectrum is sensitive to the small variation in the supramolecular structure.

  @article{ , abstract = {Site-specific modification of RNAs with functional handles enables studies of RNA structure, fate, function, and interactions. Ribozymes provide an elegant way to covalently modify RNA of interest (ROI). Here, we report that the methyltransferase ribozyme MTR1 can be employed as a versatile tool for RNA modification and labeling. Using O 6 -alkylguanine cofactors, designed in analogy to SNAP-tag substrates for protein labeling, MTR1 installs various bioorthogonal functional groups at N 1 of a specific adenosine in the RNA target. In this application of ribozyme-catalyzed RNA labeling, MTR1 is now called SNAPR. In contrast to the self-labeling SNAP-tag, which is appended to the protein of interest, SNAPR is a truly intermolecular RNA catalyst (active in trans). SNAPR assembles with the ROI to the active ribozyme, allowing for the transfer of clickable tags, such as azide and alkyne moieties, as well as photolabile groups or cross-linkers from the guanine cofactor to the ROI. Moreover, we demonstrate a two-step approach to attach labels at N 6 of the target adenosine: first, SNAPR generates N 1 A-modified RNA, followed by preparative Dimroth rearrangement to produce N 6 A-modified RNA. We demonstrate this strategy with p -azidobenzyl groups as photocrosslinker to generate covalent RNA–protein conjugates.

The full description of this mechanism is still to be elucidated. Here, we developed original chemical compounds to interfere with MBD2 and its interaction with DNA. Through convergent chemical pathways, we modified 5-methylcytosine at position N 4 and synthesised the corresponding deoxynucleosides and CpG dimers.

  @article{ , abstract = {The prebiotic synthesis and symmetry breaking of ribose are crucial processes in the origin of life. However, the prebiotic emergence of enantiomerically enriched ribose on primitive Earth remains an unresolved challenge. Herein, we propose that the prebiotic enantioselective synthesis of ribose from glycolaldehyde and glyceraldehyde can be catalyzed by minerals naturally endowed with chiral structure. The chiral mesostructured hydroxyapatite films (CMHAPFs), which consist of lattice-distorted helical nanorods, can be formed under a hydrothermal condition in the presence of l/d- malic acid (MA), a compound that may have been present during the early stages of life's emergence. An enantiomeric excess ( ee ) of 22.5% for d- ribose was achieved on the d- CMHAPFs formed by d- MA. The adsorption conformation of d -ribose on the surface of right-handed hydroxyapatite is more stable than that of l -ribose. The different energy barriers for the transition states of ribose enantiomers result in the enantioselective synthesis of ribose, which is attributed to the similar conformation between ribose and the corresponding transition state.

  @article{ , abstract = {Chlorides and fluorides solid-state electrolytes (SEs) exhibit contrasting extremes in ionic conductivity and moisture sensitivity. In light of these conflicting factors, we introduce a NaCl-based SE reinforced by mesoporous α-AlF 3 (denoted as HS-AlF 3 ), leading to a heterostructure halide architecture, designated as NHxy (where x/y represents the mass ratio of NaCl to HS-AlF 3 ). The high dispersion of NaCl and HS-AlF 3 during mechanochemical process enables the generation of defective and amorphous structures and nanodomains in NHxy along with F-Cl anion substitution effect at grain boundaries. These factors collectively promote Na ion transport in NHxy, especially along the NaCl based heterostructures with AlF 3 and NaF. This class of SEs achieves the high ionic conductivity approaching 10 −4 S cm −1 at 30 °C.

These crRNAs are synthesized via single-site chemical modification and can be efficiently purified. By integrating distinct photo-responsive chemical linkages, we achieved selective activation of crRNA activity upon irradiation with specific wavelengths, enabling orthogonal regulation of multiple genetic targets simultaneously. This method demonstrated robust OFF-ON switching capabilities in vitro, characterized by minimal leakage and rapid activation. Importantly, the approach also proved highly effective for temporally controlled gene editing in mammalian cells in vivo, achieving considerable editing efficiency following brief photoactivation. Due to its target sequence-independent, single-site modification design, this strategy may serve as a universal solution for diverse CRISPR/Cas systems, eliminating cumbersome optimization processes.

  @article{ , abstract = {Considering that hypoxia is strongly connected with tumor proliferation, metastasis, invasion, and drug resistance, it is of significant implication for alleviating the effects of hypoxia in tumor treatment. The negligible oxygen-dependent nature of type I photosensitizers (PSs) has made them appropriate candidates for the treatment of hypoxic tumors. However, the lack of effective molecular design approaches, the phototoxicity of PSs to normal tissue before and after treatment, and the drawbacks of poor hydrophilicity severely hinder the development of PSs in hypoxic tumor therapy. Thus, developing a hydrophilic PS with good hypoxia resistance and minimal side effects is an urgent but challenging problem. Herein, we present a nanotheranostic ( NanoPcN8O ) based on the self-assembly of a hydrophilic phthalocyanine derivative ( PcN8O ), a hypoxia-responsive bioreductive phototherapeutic agent suitable for activatable photoacoustic (PA) imaging and tumor therapy. Hypoxic regions in various tumors exhibit strong reductive capability, and only in such conditions did NanoPcN8O feature multiple N -oxide groups that could be bioreduced to yield the product NanoPcN8 with abundant electron-rich tertiary amine groups, which switches on the type I photodynamic and photothermal effects, facilitating the generation of type I reactive oxygen species (ROS) and heat. Better still, NanoPcN8O achieved hypoxia-induced selective PA imaging in a preclinical model. Based on these merits, the hypoxia-induced switchable type I photodynamic therapy (PDT) and photothermal therapy (PTT) strategies demonstrated remarkable phototherapeutic efficiency with high biosafety.

Two proof-of-concept molecules, BN-PhAzCz and BN-tCzAzPh, are constructed, achieving large spectral red-shifts while maintaining narrowband emission. The distorted configuration resulting from the hetero[6]helicene structure introduces twisted π–π* transition, which effectively enhances spinorbit coupling, ultimately enabling molecule BN-PhAzCz to achieve a fast reverse intersystem crossing rate (kRISC = 6.4 × 104 s −1 ).

However, achieving the simultaneous activation of O 2 and substrate molecules at low temperatures using non-precious metal catalysts remains a significant challenge. In this study, we introduce gradient oxidative Cu─O─Ti/Cu─O─Cu dual sites that enhance bimolecular activation for catalytic oxidation reactions. The catalyst, Ti-doped CuO, is synthesized on a TiO 2 support through the immobilization of Cu 2⁺ on NO 3 ⁻-grafted TiO 2 , followed by thermal treatment. The resulting gradient oxidative Cu─O─Ti/Cu─O─Cu sites exhibit exceptional catalytic oxidation activity for NH 3 and various VOCs at low temperatures, matching the performance of precious metal-based catalysts. Notably, during NH₃ oxidation, Cu─O─Ti sites enhance the activation of both O₂ and NH₃. HNO intermediates formed on Cu─O─Ti sites react with NH intermediates on neighboring Cu─O─Cu sites—producing N₂ and H₂O via an imide mechanism—which effectively lowers the reaction barrier for catalytic NH₃ oxidation.

  @article{ , abstract = {The inferior fill factor (FF) is one of main reasons impeding further improvement of power conversion efficiencies (PCEs) in organic solar cells (OSCs). But no theoretical framework for high FFs has been established yet. Herein, an efficient strategy is developed to enhance FFs via introducing a small molecule, CNDT, into active layer. CNDT increases the electron donor/acceptor interface disorder, raises the energy barrier for charge back transfer, and thus reduces bimolecular recombination rate constant ( k rec ). We show that CNDTs distribute across electron donor/acceptor interfaces of D18:Y6+, disturbe the molecular stacking of Y6, lead to a more disordered interfaces, while maintaining higher crystal quality compared to D18:Y6. This disorder, along with a higher energy of charge transfer states magnifies the energy barrier for charge recombination, decreases charge recombination rate/ratio, reduces k rec , and inhibits bimolecular recombination in devices. Therefore, FFs of OSCs are improved from 75.78% (D18:Y6) to 81.13% (D18:Y6+), yielding a higher PCE of 19.45%. Moreover, D18:L8-BO+ based OSCs feature FFs over 83%, a record for OSCs so far, with PCEs reaching 19.80%.

  @article{ , abstract = {Molecular geometry plays a crucial role in determining the physical and chemical properties of organic semiconductor materials. However, there is little research on the molecular geometry-property relationship of A-DA'D-A type small molecule acceptors (SMAs), which are the most representative organic semiconductor materials used in organic solar cells (OSCs). In this work, we used dichlorine-substituted benzene as the A’ unit to overcome the geometry constraints imposed by the conventional A’ unit that has a large size. Four isomers of benzodipyrrole-based SMAs (C-Cl46-Cl, Ɂ-Cl46-Cl, M-Cl46-Cl, and S-Cl46-Cl) with C-, Ɂ-, M-, and S-shaped molecular geometries were synthesized, and the effect of molecular geometry on their photovoltaic performance was studied. We revealed that the molecular geometry influences the physicochemical and photovoltaic properties in three aspects: 1) intrinsic physicochemical properties, including energy levels, absorption, and reorganization energy; 2) molecular stacking pattern, which governs the exciton diffusion and charge transport processes; and 3) donor–acceptor interaction and miscibility. We found that the C-shaped molecular geometry possesses a suitable energy level and absorption range, dense and ordered molecular stacking, and improved donor–acceptor interaction and miscibility. These advantages enable a record-high power conversion efficiency (PCE) of 19.94% (certified as 19.54%) for the binary OSCs based on D18:C-Cl46-Cl active layer. The other SMAs showed weaknesses in different aspects, such as limited absorption of Ɂ-shaped SMA, large reorganization energies and loose molecular stacking of M-shaped SMA, low solubility and strong aggregation of S-shaped SMA. These properties resulted in inferior photovoltaic device performance. These findings on the molecular geometry-property relationships will be instructive for future molecular design of high-performance A-DA'D-A type SMAs.}, archive = {J_ANGEW}, author = {Yufei Gong and Senke Tan and Xiaojun Li and Shucheng Qin and Xiangjin Li and Tianwei Zou and Yuechen Li and Meng Yuan and Ziyue Zhang and Huawei Hu and Tongling Liang and Jinyuan Zhang and Lei Meng and Feng Liu and Yongfang Li}, doi = {10.1002/anie.202505366}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {25}, pages = {e202505366}, shortjournal = {Angew.

  @article{ , abstract = {Conjugating hydrophobic tags to oligonucleotides facilitates the swift and efficient creation of membrane-anchored DNA nanoprobes. However, the membrane-anchoring of these hydrophobic tag-conjugated DNA nanoprobes (HT-DNPs) lacks specificity among different cell types. To address this challenge, we herein report a conformational switching-based strategy for selectively anchoring HT-DNPs to target cells. In our design, HT-DNPs with extended or compact conformations possess weak or strong interactions with cell membrane, respectively. Thus, interactions between HT-DNPs and cell membrane can be dynamically controlled by altering the conformation of HT-DNPs. Initially, the extended HT-DNPs exhibit poor membrane-anchoring ability that is impute to their weak hydrophobic interactions with cell membrane. However, in slightly acidic conditions, HT-DNPs intercalated with DNA i-motif-forming sequences can fold into a compact conformation and exhibit strong hydrophobicity, thus achieving selective and efficient anchoring of HT-DNPs to target cells in such environments. Utilizing this method, we constructed HT-DNPs for imaging of ATP in the tumor microenvironment (TME). Our results indicate that these HT-DNPs can effectively accumulate at tumor sites for specific ATP imaging following intravenous injection.

Moreover, dissociation kinetics, mutational analysis, and molecular dynamics simulations revealed an overlap between the binding modes adopted by the natural and mirror-image proteins to natural dsDNA.

The atomically dispersed Ni sites with electron-rich state enable a Pauling-type (end-on) O 2 adsorption configuration and a modest binding strength of O 2 and OOH*, largely avoiding the O─O bond cleavage. Besides, the formation of electron-deficient S sites weakens the S─H ads bond, facilitating *H ads migration to adjacent Ni sites and accelerating the hydrogenation kinetics of O 2 to OOH* intermediate.

Specifically, the cobalt in perovskite SrCoO 3 (SC) with a low-spin state demonstrates an 18 times higher ammonia yield rate compared to that in Co 3 O 4 and 1.5 times higher than cobalt in perovskite LaCoO 3 (LC). The low spin states of cobalt in SC enable better control of the eNRR reaction pathway over the transformation of *N 2 H to *NHNH or *NNH 2 , resulting in alternating hydrogenation in SC rather than distal hydrogenation in LC with a high spin state.

  @article{ , abstract = {Functionalization of graphene derivatives is a common approach to tune material properties for use in various applications. Because of the low reactivity of the unsaturated carbon lattice of graphene, not only are few chemical approaches suitable for successful functionalization, such as those involving highly reactive in situ formed radical species or nitrene and carbene compounds, but also the degree of functionalization is usually limited, modifying only a few percent of the carbon atoms. Typically, uncontrolled side reactions such as homocoupling and oligomerization of newly introduced functional groups can occur instead of direct coupling to the carbon lattice. We want to turn this unwanted side reaction into an advantage and use intentionally formed covalent dendrimeric oligophenylene structures for secondary functionalization. We show that these oligomeric structures can be grown to specific thicknesses and used for further functionalization with bromomethyl groups at high density on the surface. This functionalization opens further avenues for subsequent nucleophilic substitution, as exemplified by the introduction of versatile azide, nitrile, and phosphonate groups. The results presented here are not only applicable to large oligophenylene structures, but also demonstrate that, in principle, single aryl moieties on graphene of any size and density can be successfully functionalized.}, archive = {J_ANGEW}, author = {Christian E.

  @article{ , abstract = {The range of functional proteins that can be prepared by chemical protein synthesis includes those bearing complex modifications and incorporating d -amino acids, and exceeds what can be accessed by biological means, but the technique is still limited by the unfavorable solution behavior of many synthetic protein intermediates in buffer, leading to inefficient ligation, purification, and in vitro folding. One approach to address this limitation is the use of temporary structural supports—chemical modifications, usually solubilizing functionalities such as polyamines or carbohydrates—that are installed on either the backbone or side chains of the synthetic protein intermediates and removed at a later stage of chemical protein synthesis. The basic processes for introducing and removing such temporary structural supports are reminiscent of the canonical protecting groups ubiquitous in organic chemistry. However, unlike the synthesis of small organic molecules, where solubility is rarely an issue, the purpose of temporary structural supports is to modulate the solution behavior of the synthetic protein intermediates to prevent them from aggregation, precipitation, or retention in unfavorable solvation-phase conformations. In this review, we summarize recent advances in the development of temporary structural supports for chemical protein synthesis and organize them into three categories: 1) Temporary structural supports to improve solubility; 2) Temporary structural supports to assist chemical ligation; and 3) Temporary structural supports to promote in vitro folding.}, archive = {J_ANGEW}, author = {Yanbo Liu and Dongyang Han and Lei Liu}, doi = {10.1002/anie.202504405}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {25}, pages = {e202504405}, shortjournal = {Angew.

The production of high-purity O 2 via non-thermal-driven pressure-swing adsorption has the advantages of portable operation and low energy consumption. However, effectively removing trace amounts of argon (Ar) impurities in this process is indispensable, and it is a fundamental challenge to achieve the preferential adsorption of inert Ar atoms over polar O 2 molecules instead of traditional thermodynamic or molecule sieving strategies. Herein, we have demonstrated this problem was addressed by integrating spheroidal shape-matched interactions to fit the spheroid Ar atoms while repulsing the linear O 2 molecules. Using this strategy, customized TYUT-20 enables the exceptional recognition of Ar atoms over O 2 molecules, demonstrating an unprecedented Ar adsorption capacity of up to 14.5 cm 3 g −1 and a top-performing Ar/O 2 (1.54) selectivity at 298 K and 1 bar.

Artificial co-transporters remain difficult to construct since they have a much more complex ion-sieving property.

We here demonstrate a method to construct artificial co-transporters, using a porous organic framework membrane which has a relatively disordered stacking structure and rich quaternary ammonium groups paired with counter-ions. This imparts the membrane with extremely narrow pores (∼0.3 nm) and almost no surface charge, enabling size-based high alkaline ion selectivity against other cations, high Cl − selectivity against other anions, but almost no alkaline ion/Cl − selectivity.

Despite the vivid research on Eu 2+ -activated alkali lithooxidosilicates, little to nothing is known about the possible luminescence with other activator ions than Eu 2+ . The more abundant transition metal ion Mn 2+ is a potential alternative emitter with tunable emission over the visible spectral range. Mn 2+ -activated alkali lithooxidosilicates show two emission bands in the green and red spectral range, respectively, making them intriguing candidates for one-component phosphor-converted white light-emitting diodes. A total of seven Mn 2+ activated compounds were prepared to elucidate possible trends. The results show that the ratio between green and red emission correlates to the size of the available activator sites and is easily controlled by the composition of the alkali lithooxidosilicate host compounds. Temperature-dependent luminescence studies reveal that thermal quenching occurs slightly above room temperature for those compounds, which may be connected to the comparably low band gaps for silicates ( E g < 6 eV) and a consequent thermal ionization of excited electrons into the conduction band.

  @article{ , abstract = {Precise, controlled, and living polymerization of cyclosiloxanes is garnering considerable attention due to the distinct properties and promising applications of polyorganosiloxanes in various fields. In this contribution, photo-induced living anionic ring-opening polymerization of cyclosiloxanes is achieved by developing an efficient photobase generator (PBG). Structure-photoactivity analysis of the photo-latent catalyst is undertaken by synergistic density functional theory (DFT) calculations and experimental investigations. DFT calculations predict the superior photoactivity of the synthesized PBG2 (i.e., 2-[(9-oxo-9H-thioxanthen-2-yl)oxy]acetic-1,5,7-riazabicyclo[4.4.0]dec-5-ene) and provide insights into the structure-catalytic activities, which is confirmed through the experiments. Polyorganosiloxanes with predetermined molar masses and low dispersities ( Đ < 1.30) are produced through on-demand cleavage of PBG2 under various light intensities, different PBG2 loadings, and sequential addition of monomers. On–off light switching enables the polymerization in a rate-controlled manner. Later on, mechanistic insights by DFT calculations identify the anionic species for nucleophilic attack and reveal that the reversible equilibrium involving anionic species, catalyst cations, and ion pairs contributes to precise control over chain growth during photopolymerization. Furthermore, deterministic kinetic simulation disentangles the effects of the cleavage rate and loading of PBG2 on polymerization kinetic behaviors.

Inspired by the low and low speed of sound of fluorinated liquids, we explored whether this behavior in liquids can be extended to polymers. We synthesized seven partially fluorinated (9%–17% atomic fraction F) and ten conventional polyurethanes. Fluorinated polyurethanes exhibit a reduction in up to 50% compared to their nonfluorinated counterparts.

  @article{ , abstract = {The α-methylene-γ-butyrolactone tulipalin A, a defense compound found in tulips, can polymerize via addition at the vinyl group or via ring-opening polymerization, making it a highly promising monomer for bio-based polymers. Since the biosynthesis of tulipalin A in plants remains elusive, we propose an alternative pathway for its synthesis starting from the terpenoid intermediate isoprenyl acetate. While fungal unspecific peroxygenases showed a preference for the unwanted epoxidation of the exo- olefin group, bacterial alkane monooxygenases were selective for terminal hydroxylation. By combining protein engineering based on de novo structure prediction of the membrane enzymes with cell engineering, the specific activity was increased 6-fold to 1.83 U g cdw −1 . Oxidation of the formed allylic alcohol by a three-enzyme cascade and subsequent lactonization yielded tulipalin A.

Using multi-temperature high-resolution single-crystal X-ray diffraction, we investigated the structural dynamics of the wine-rack-like framework of Cd-Tz and compared it with that of positive thermal expansion (PTE) CPs Zn-Tz and Mn-Tz with similar framework topology. We show that nZTE in Cd-Tz is a consequence of two monotonic and opposing trends with PTE ( α a , α c ∼22 MK −1 ) in the ac plane and negative thermal expansion (NTE) in the b direction ( α b ∼−47 MK −1 ). A new mechanism for the uniaxial NTE is established based on concerted out-of-plane single atom libration of similarly oriented adjacent triazole rings in the wine-rack motifs. X-ray electron density analysis and modeling of low-temperature vibrational anharmonicity reveals the role of Cd-triazole bonds and hydrogen bonds in promoting the single atom libration.

Herein, two nonfullerene acceptors, namely BTP-N6 and BTP-V6, are designed and synthesized to construct as-cast OSCs by introducing linear alkyl chains adjacent to the pyrrole moiety. The reduction of steric hindrance attributable to linear chains engenders diminished dihedral angles of molecular skeletons, thereby promoting compact and face-on oriented molecular stacking. Moreover, BTP-V6 featuring vinyl-functionalized linear chains manifests additional interaction sites with neighboring molecules to instigate enhanced π–π stacking during rapid film-formation process and engenders the formation of a refined double-fibril network morphology, which facilitates exciton dissociation, bolsters charge carrier transport, and suppresses recombination loss.

These DNA sequences are designed to hybridize, creating a “locked” hairpin-like structure. Upon proteolytic cleavage, the initiator strand is released, triggering the activation of CRISPR-Cas12a enzymes and producing an amplified fluorescence response. CLIPs generate more than 20-fold turn-on signals at room temperature (25 °C), significantly outperforming commercial probes by yielding ∼40-fold lower limits of detection (LOD) at 100-fold lower concentrations. Their versatility enables the detection of various disease-relevant proteases—including the SARS-CoV-2 main protease, caspase-3, matrix metalloproteinase-7, and cathepsin B—simply by altering the peptide sequence. Importantly, CLIPs detect cathepsin B in four different colorectal cancer cell lines, highlighting their clinical potential. Taken together, the sensitivity (LOD: ∼88 pM), selectivity, and rapid assay time (down to 35 min), combined with the ability to operate in complex biological media with minimal sample preparation, position CLIPs as powerful chemical tools for activity-based sensing of functional enzymes.}, archive = {J_ANGEW}, author = {Dylan M.

Herein, we investigate the optimum deposition sites for Li 0 atoms within typical LPS configurations, encompassing crystalline, lithiated, and degraded structures, with their ionization levels employed as descriptors to determine the preferential state (Li 0 /Li + ) of the interstitial Li. Our results suggest that both bulk LPS and solid electrolyte interphase (SEI) layer are predicted to be electrochemically resistive upon Li 0 deposition.

This Hoogsteen base pair, located adjacent to a dinucleotide apical loop, exists in dynamic equilibrium with a minor Watson-Crick conformation (population ∼11% and lifetime ∼55 µs). Extending the apical loop to three residues inverted the equilibrium, making Watson-Crick the dominant state and the Hoogsteen conformation recognized by TnpA a minor state (population ∼14% and lifetime ∼28 µs).

In this study, we present an enzymatic reductive amination strategy to attain this objective. By engineering the enzyme pocket of the sole imine reductase (IRED) M5, we successfully synthesized over 80 cis / trans and axially chiral 4-substituted cyclohexylamines in a stereo-complementary fashion, adhering to industrial standards, via the reductive amination of 4-substituted cyclohexanones. Mechanistically, the reshaping of the enzyme pocket allows the optimized variants to distinguish between different imine precursors and selectively bind their specific configurations with favorable binding energies, thereby facilitating the generation of stereochemically distinct products.

  @article{ , abstract = {Selective capture of paraffin from olefin that permits one-step purification of olefin is significantly important, yet developing adsorbents with high selectivity and hydrophobicity remains a daunting challenge. Although aromatic environments can enhance paraffin affinity and hydrophobicity through nonpolar interactions, water adsorption still occurs in regions distant from the aromatic rings, as well as in secondary pores that are always overlooked. Herein, we reported an ultramicroporous porous coordination polymer (ZnFPCP) featuring blade-like circular phenyl paraffin nanotraps. As further validated by density functional tight binding (DFTB) calculations, grand canonical Monte Carlo (GCMC) simulations, and in situ Fourier-tansform infrared absorption (FT-IR) analysis, these ultramicroporous paraffin nanotraps created by surrounding benzene rings enhance the paraffin-selective adsorption, and the segmented spaces between adjacent nanotraps in the blade-like structure, combined with hydrophobic petal-like secondary pore channels enclosed by fluorinated functional groups, further mitigate the water co-adsorption. Remarkably, ZnFPCP exhibited outstanding ideal adsorption solution theory (IAST) selectivity (C 3 H 8 /C 3 H 6 : 2.08, C 2 H 6 /C 2 H 4 : 2.93) under ambient conditions and record-breaking C 3 H 8 /C 2 H 6 uptake at low pressures.

Its high optical dispersion, extraordinarily high mechanical strength, and unparalleled thermal conductivity have long made it a material of interest for applications such as high-temperature electronics and as wear-resistance coatings. More recently, diamond has emerged as a material with a wide range of applications in chemistry and biology. The high intrinsic stability of diamond, coupled with the ability to modify diamond surfaces with a wide range of inorganic, organic, and biological species via highly stable covalent linkages, provides a wealth of opportunity to couple diamond's chemical properties with its extraordinary physical properties. The practical utility of diamond has been greatly expanded in recent years through dramatic advances in the ability to produce diamond in bulk, thin film, and nanoparticle form, with controlled doping and purity at modest cost. These advances, together with diamond's highly stable and tunable surface chemistry with versatility of physical structure enable a wide range of emerging applications of interest to chemists, including quantum science, biomedicine, energy storage, and catalysis. Yet, to fully exploit the unique properties of diamond, some formidable chemical challenges lie ahead.

  @article{ , abstract = {The intracellular reduction of Pt(IV) prodrugs is crucial for their anticancer efficacy. However, the major components responsible for the reduction of Pt(IV) complexes within live cells remain elusive. Herein, we developed an aminoluciferin-functionalized Pt(IV) complex, Pt-Luc , that can be used as a bioluminescent reporter for real-time monitoring of Pt(IV) reduction in live cancer cells by capturing immediate bioluminescent signals from the released aminoluciferin. Utilizing this powerful reporter, we found that the reduction of Pt(IV) prodrugs in live cancer cells significantly slows down when cysteine levels are reduced, while the levels of glutathione do not impact the reduction rate. Further investigation reveals that reactive cysteines in proteins, rather than small-molecule thiols, play a primary role in reducing the Pt(IV) complex. In vivo studies reveal a substantial 63% decrease in bioluminescence from Pt-Luc in thiol-blocking tumors in mice, reinforcing the pivotal role of reactive cysteines in Pt(IV) reduction.

Using solution-state NMR and biophysical techniques, we discovered an unexpected sequence-specific effect of C m on the folding kinetics of bcl2Mid G4. Specifically, substituting cytosine at position C6 with C6 m slows down G4 folding kinetics and influences the equilibrium between major and minor structures in the presence of K + ions. Notably, the increased population of the minor structure enabled the characterization of its previously unidentified topology. Additionally, the presence of a single C m residue induces local structural rearrangements in the major G4 structure and decreases its thermodynamic stability. Furthermore, we found that the zinc finger 3 motif of the Sp1 transcription factor preferentially binds to the minor G4 structure.

In this study, we propose a symmetry-breaking-induced amorphization strategy to achieve an exceptionally high Ce 3+ ratio by B doping, which facilitates the reduction of Ce 4+ to Ce 3+ in amorphous CeO 2 . First-principles calculations and infrared spectroscopy reveal that B doping with three excess electrons induces the formation of planar triangular B–O₃ units by disrupting the original high-symmetry structure of CeO 2 , facilitating the spontaneous transition to the amorphous phase. Electronic structure analysis confirms that even a modest 7.5% B doping can significantly elevate the Ce 3+ ratio to 85.7%.

Combining in-situ characterization with computational calculations, we reveal that compared to COF-BD1 containing two diversion charge transfer pathways, the charge transfer pathway in COF-BD2 is confined to a confluence due to the electron-deficiency effect of nitrogen, which greatly accelerates the intermolecular and out-of-plane charge transfer.

  @article{ , abstract = {The electrochemical synthesis of organic compounds from CO 2 can potentially alleviate climate change by hampering the atmospheric accumulation of greenhouse gases. The production of carbohydrates from CO 2 reduction will have promising applications for the manufacturing of valuable, multi-carbon compounds that are traditionally produced from the petrochemical or agricultural industries. In this work, we analyzed the copper-catalyzed electrochemical reduction of glycolaldehyde, a commonly observed trace CO 2 RR product that has been previously proposed as an intermediate for alcohol formation. We determine that glycolaldehyde is not the main intermediate on polycrystalline copper-based electrocatalysts that selectively produce ethanol. In an unbuffered electrolyte, the cathodic hydroxide ions produced induce the coupling of glycolaldehyde to tetroses in the solution phase, yielding a maximum glycolaldehyde-to-sugar conversion of 47.2% under ambient conditions. Using in situ infrared spectroscopy coupled with density functional theory (DFT) calculations, we show that glycolaldehyde reduction to alcohols proceeds via adsorption of its enol tautomer, η 2 (C,C)─CHOH═CHOH. Our findings not only shed light on the C 2 alcohol formation pathways during CO 2 RR, but also imply that a CO 2 electrolyzer can potentially produce C 4 carbohydrates via CO 2 reduction to glycolaldehyde followed by C─C coupling in the solution phase, with only a high local pH needed to drive the tetrose formation step.}, archive = {J_ANGEW}, author = {Ernest Pahuyo Delmo and Haichuan Zhang and Jessa Vispo De Guzman and Rans Miguel Nunag Lintag and Juhee Jang and Yao Yao and Yinuo Wang and Shangqian Zhu and Tiehuai Li and Mingguang Pan and Hongming Xu and King Lun Yeung and Minhua Shao}, doi = {10.1002/anie.202505274}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {24}, pages = {e202505274}, shortjournal = {Angew.

Our investigations demonstrate that the CH 4 selectivity exhibits a volcano-type dependence on the Cu─O bond length, and the optimized value is accessible at about 1.951 Å.

Stable isotope labeling experiments reveal all biosynthetic building blocks for celluxanthene assembly.

Furthermore, the recovered Li + in solution leads to the elevated ionic strength in the electrolyte, enhancing the concentration of [Fe(CN) 6 ] 4− to a remarkable level of 1.74 M. Utilizing the above catholyte, an AZFFB cell demonstrates the cycling life extending to 11 000 cycles with a degradation rate as low as 0.00019% per cycle and 0.09% per day at a current density of 120 mA cm −2 . This study introduces a straightforward and efficient protocol that eliminates additional intermediate processes, achieving effective Li + recovery from spent LFPs and subsequent utilization in flow batteries. The resulting AZFFB exhibits high energy density and long lifespan, positioning it as a promising candidate for large-scale energy storage solutions.}, archive = {J_ANGEW}, author = {Junqiang Wang and Zhexuan Liu and Zhizhao Xu and Mei Ding and Bo Lu and Chuankun Jia and Guangmin Zhou}, doi = {10.1002/anie.202503109}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {24}, pages = {e202503109}, shortjournal = {Angew.

The yield of phenolic monomers reached 46.0wt.% (rich in 4-propylguaiacol and 4-propylsyringol) in the RCF of birch wood under high H 2 pressure and using methanol as the solvent. But, under N 2 atmosphere the dominant monomers shifted to 4-(prop-1-enyl)guaiacol and 4-(prop-1-enyl)syringol (79.6% selectivity) with 35.8wt.% yield of total monomers using the same catalyst. The developed catalyst can also transform native lignin in other biomasses such as pine and corn stover. Mechanistic investigation using different model compounds and deuteration indicates that removal of the C γ ─OH in methanol-extracted lignin fragments occurred before obtaining the monomeric lignin fragment, and the C α ─OH and β─O─4 bonds were then cleaved simultaneously to form 4-(prop-1-enyl) substituted monomers.

To address these issues, a functionalized molecule with multiple hydrogen bond acceptors, 4-Carboxyphenylboronic acid (4-BBA), is designed in the perovskite precursor for modulating perovskite crystallization, which achieves uniform and stress-relaxation perovskite film and forms a robust bridging structure anchored at the buried interface.

Extending this principle to temporally self-sorted synthetic assemblies is key to developing multi-component biomimetic systems. Herein, we present a strategy towards this direction, to achieve sequential self-sorting of supramolecular assemblies through differences in the chemical-reactivity of monomers, coupled to redox-reactions. This approach exploits the distinct redox potentials of monomers to achieve precise temporal-control over self-sorting, while inherent structural mismatches among monomers ensure the kinetic stability of self-sorted state. Reduction reactions transiently disrupt their assemblies into dormant inactive monomeric states, while subsequent kinetically controlled reassembly occurs via reversible oxidation reactions. Finally, utilizing this sequential self-sorting, we aim to mimic multicomponent cellular self-organization by demonstrating the kinetically controlled growth of self-sorted structures in the presence of model protocells, using lipid vesicles as compartments.

Upon visible light irradiation the small number of oxidized rhodamines, Rhod-PM, acts as a photosensitizer to generate singlet oxygen capable of oxidizing the OFF state LRhod-PM thereby switching it to its ON state.

Traditional methods for electrochemical olefin hydrofunctionalization, for example, hydrocarboxylation, rely on anion intermediates and follow an electrochemical–chemical–electrochemical–chemical (ECEC) mechanism involving olefin reduction, carboxylation, further reduction, and protonation. Enhancing terminal carboxylate selectivity often requires a proton source, reducing functional group tolerance and favoring proton reduction over olefin reduction. Alternating polarity, a nascent technique in organic electrochemistry, can improve product selectivity by influencing electron transfer rates and electrode surface species. Herein, we report the use of alternating polarity to selectively generate radical anions from styrene derivatives, using electrochemical hydrocarboxylation as a model. This approach shifts the mechanism to an electrochemical–chemical–chemical (ECC) pathway, where the final step involves hydrogen atom transfer.

Subsequently, the locations with more defects could be preferentially etched to form voids or mesopores, meanwhile oriented recrystallization interconnects the nanoshells into a unified architecture along the [001] direction. Benefiting from the easily accessible bifunctional metal/acid sites and the capability for reactant accumulation, the resultant multi-shell hollow Ni-loaded zeolite catalysts show significantly enhanced catalytic activity in the hydrodeoxygenation of stearic acid into liquid fuels.

  @article{ , abstract = {Photocatalytic C 2 H 4 synthesis from CO 2 and H 2 O by utilizing solar energy represents a promising sustainable process, yet its efficiency remains significantly limited. Herein, we proposed a dual-engineered strategy integrating 3D ordered macroporous (3DOM) architectures with heteronuclear dual-metal active sites to synergistically promote the photocatalytic C 2 H 4 production. As an example, the Cu/3DOM-In 2 O 3 photocatalyst was synthesized by in situ incorporating Cu single atoms (Cu SAs) into 3DOM In 2 O 3 through a template-assisted pyrolysis process. The strong interaction between Cu SAs and In 2 O 3 resulted in the formation of charge-polarized Cu─In active sites along with abundant oxygen vacancies (O V s). 3DOM architectures serving as special nanoreactors displayed significant advantages in promoting CO 2 enrichment and confining key intermediates, thereby increasing *CO coverage. Meanwhile, the charge-polarized Cu─In active sites effectively mitigated electrostatic repulsion and promoted the formation of *CO + *CHO intermediates, resulting in a thermodynamically spontaneous C─C coupling step. Therefore, the Cu/3DOM-In 2 O 3 photocatalyst exhibited robust CO 2 reduction to C 2 H 4 , achieving high C 2 H 4 evolution rates under various CO 2 concentrations, including pure CO 2 , 10% CO 2 in Ar (simulated flue gas), and 0.04% CO 2 in Ar (simulated air).

Here, we introduce J-type supramolecular polymerization as an effective strategy to address this challenge. By attaching amide groups to point-chiral anthraquinone luminophores, the formation of directional hydrogen bonds facilitates efficient chirality transfer from peripheral stereocenters to anthraquinones, resulting in supramolecular polymers with amplified chiroptical asymmetry. More importantly, the incorporation of acetylene spacers reduces torsional angle of the anthraquinone core compared to the nonacetylene control compound (1.81° versus 33.4°), promoting J-aggregation and increasing emission intensity. This structural optimization enables the supramolecular polymers to achieve a circularly polarized luminescence brightness of 13.8 M⁻¹cm⁻¹, marking a significant advancement in point-chiral luminophore systems. Furthermore, the integration of Förster resonance energy transfer into these supramolecular polymers allows for the fabrication of color-tunable circularly polarized electroluminescent devices.

Compared to the non-mannosylated nanomotors, mannosylated c-CLEnM exhibited enhanced motion and higher targeting efficiency to cells in glucose-containing ionic environments. The unexpected acceleration in speed resulted from the surface modification of these nanomotors with a glycopolymer layer, which increased the zeta potential and created a shielding effect that mitigated the influence of the surrounding ions.

Here, we present an azetidinecarboxamide strategy that addresses these challenges by integrating brightness enhancement and ligand conjugation capabilities within a single molecular framework. The azetidinecarboxamide core suppresses twisted intramolecular charge transfer (TICT), thereby enhancing fluorescence quantum yield. Its carbonyl group provides a versatile site for conjugating a wide range of targeting ligands, enabling the rapid development of diverse and tunable fluorophore–ligand conjugates. This streamlined approach reduces synthetic complexity, accelerates probe development, and is compatible with a wide variety of fluorophores, such as coumarin, naphthalimide, NBD, rhodol, rhodamine, and silicon–rhodamine, facilitating the creation of high-performance, multifunctional probes for advanced cellular imaging.}, archive = {J_ANGEW}, author = {Ning Xu and Qinglong Qiao and Chao Wang and Wei Zhou and Pengjun Bao and Jin Li and Shaowei Wu and Xiaogang Liu and Zhaochao Xu}, doi = {10.1002/anie.202505579}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {23}, pages = {e202505579}, shortjournal = {Angew.

As a structurally programmable molecular building block, SrPd 12 is used to evolve from monomer via dimer to supramolecular aggregates in a controlled manner. In such process, the open-shell-type monomers are covalently integrated into bowl- or cage-like dimers via a direct or indirect splicing strategy. Upon that, hydrogen bond and hydrophobic effects are further hired to fabricate supramolecular aggregates of varied host–guest archetypes, thereby completing a hierarchical construction. In consideration of the combined advantages of noble metals and polyoxometalates in cancer treatment, both in vitro and in vivo anti-tumor assays of these SrPd 12 -derived POPs were studied in detail.

Intriguingly, by freezing this slow equilibrium, facilitated by strong and stable H-bonding, we could achieve selective isolation of the tetranuclear species ( 3a , b - II ). On the other hand, encapsulation of an anionic guest, ClO 4 , led to exclusive formation of the guest encapsulated trinuclear Ag I -NHC complex, 3a - I . This is unprecedented and marks the first instance where selective isolation of both the species involved in an equilibrium using a C-donor ligand could be attained. In contrast, distinct behavior was observed with the Au I ion, possessing the same linear geometry, however, with stronger M–C NHC bonds. In this context, a stable non-exchangeable ≈1:1 mixture ( 4a , b ) of the tri- and tetranuclear Au I -NHC complexes were obtained via transmetalation of both equilibrating ( 3a , b ) and the H-bonded tetranuclear Ag I -NHC complexes ( 3a , b - II ). Moreover, by aptly adjusting the reaction parameters of transmetalation process, the trinuclear Au I -NHC complex ( 4a , b - I ) could indeed be obtained selectively.

  @article{ , abstract = {Aside from activity and selectivity, catalyst stability is a key focus in heterogeneous catalysis research. Although sintering of metal species has been considered the primary cause for deactivation of metal catalysts, our study reveals that the loss of activity at low reaction temperatures in the CeO 2 -supported Pt (Pt/CeO 2 ) catalyst in complete propane oxidation is due to the dispersion of Pt ensemble sites (nanoclusters) and their subsequent operando conversion into Pt single atoms under reaction conditions. These Pt single-atom species exhibit low reactivity and act as spectators in the low-temperature reaction region. To address this issue, we engineered the surface of CeO 2 by introducing NbO x , which does not directly interact with Pt. Instead, NbO x blocks the strong binding sites for Pt on CeO 2 , thereby preventing Pt redispersion/fragmentation and preserving reactive Pt ensembles. This strategy led to a remarkable 37-fold increase in the reaction rate compared to the Pt/CeO 2 catalyst. Our findings emphasize the importance of suppressing the formation of noble metal single-atom spectators through innovative surface engineering strategy.

  @article{ , abstract = {Rechargeable aqueous metal batteries offer inherent safety and low cost due to the predominance of water in their aqueous electrolytes, yet their practical applications are severely limited by electrolyte freezing under subzero conditions. Drawing inspiration from the mechanism of antifreeze proteins (AFPs) that protect living organisms from freezing damage, we synthesize oxidized quasi-carbon nitride quantum dots (OQCNs) featuring a regularly in-plane structure commensurate with the prism face of hexagonal ice crystal. At an ultralow concentration, the as-synthetic OQCNs effectively mimic AFP functionalities by controlling ice crystal morphology, suppressing ice growth kinetics, and inhibiting ice recrystallization. This synergistic mechanism preserves continuous ion transport pathways while mitigating physical damage to battery components caused by ice crystal growth. Molecular dynamics simulations demonstrate that the Gibbs–Thomson effect underpins the suppression of ice growth, avoiding complete solidification of the electrolyte under subzero conditions.

We report here a pyridyl-tethered isolable azomethine ylide ( AY ) that activates a series of H−E bonds (E═B, Si, Al, O) in FLP-like fashion. The reactions are probed mechanistically by DFT calculations and each case appears to be distinct from others. While the HBpin activation is stepwise, the same of PhSiH 3 is concerted. The AlH 3 activation is also stepwise but takes place across the 1,5-(C + /N − ) dipole. The hydrolysis of AY fits better with a “relay” mechanism with two H 2 O molecules working in tandem. The B−B bond of B 2 pin 2 is also cleaved but in an intriguingly different way, by delivering both the Bpin moieties at the carbenic site. Though the challenging H 2 activation fails, a transfer hydrogenation of AY by NH 3 •BH 3 is readily achieved. AY also undergoes cycloadditions with various dipolarophiles including unactivated alkene and alkynes. In this regard, AY makes an interesting distinction between CO 2 and CS 2 by staying inert to the former but easily cycloadding the latter. DFT analysis justifies this dichotomy by showing the cycloaddition of CO 2 as thermodynamically disfavored.}, archive = {J_ANGEW}, author = {Sudip Baguli and Subham Sarkar and Dibyendu Mallick and Debabrata Mukherjee}, doi = {10.1002/anie.202504737}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {23}, pages = {e202504737}, shortjournal = {Angew.

Although these modifications preserve the frontier molecular orbital distribution with large oscillator strengths, they significantly influence excited-state dynamics and molecular aggregation even at low doping concentrations. Introducing Ph substituents extends the π–conjugation extension of CzBN, promoting closer molecular packing, detrimental molecular aggregation, and significantly broadening the excited-state absorption (ESA) band, which negatively impacts lasing performance. In contrast, CzBN-tBu, incorporating t -Bu groups as nonconjugated substituents, demonstrated reduced molecular aggregation and a distinct separation between the ESA band and stimulated emission region. Consequently, the optimal distributed feedback lasing performance is achieved by CzBN-tBu across various doping concentrations, resulting in the lowest lasing threshold of 3.4 µJ cm −2 .

This coassembly undergoes spontaneous and highly efficient borate esterification under ambient conditions, inducing nanoscale morphological evolution, and an inversion of supramolecular chirality.

This study explores the catalytic interconversion of pyruvate and lactate, mediated by lactate dehydrogenase in biochemical systems, using inorganic zeolite Y-supported Ni nanoparticles (Ni/Y) under mild hydrothermal vent conditions. Our results demonstrate that Ni/Y effectively catalyzes the hydrogenation of pyruvate in an inert environment, facilitated by the in situ generation of H₂ through an autocatalytic reaction between Ni/Y and H₂O.

Unlike conventional synthetic slippery coatings requiring laborious surface pretreatments, biofilm sheets formed on demand assemble a durable nanotextured framework on diverse substrates with multiple material categories and surface topologies, serving as hydrophobic lubricant reservoirs. Employing this renewable material enables the scalable and sustainable coating production. The resulting optically transparent and highly flexible coatings manifest exceptional self-cleaning properties, readily shedding both waterborne and oily liquids over a broad viscosity range. Notably, the synergy between the corrosion-protective extracellular matrix and nonstick slipping motion confers unprecedented antibiofouling efficacy and corrosion resistance.

  @article{ , abstract = {Single-atom catalysts (SACs) depend significantly on their support properties, and organic polymers have emerged as promising candidates due to their tunable physicochemical properties and diverse functional groups. However, the high-temperature carbonization commonly required for conventional organic polymer-supported SAC fabrication often leads to the loss of these functional groups, thus weakening metal-support interactions and catalytic performance accordingly. Herein, we report a sustainable strategy to synthesize nitrogen-functionalized lignin-based phenolic resin (N-LPR) supports for stabilizing atomically dispersed palladium (Pd) without carbonization. Using ammonia solution (NH 3 ·H 2 O) as both the nitrogen source and catalyst, high molecular weight lignin fractions (L3) were transformed into N-L3PR-50% supports with a unique nano-chain-like structure, high surface area, and abundant amine groups, which can directly anchor Pd sites under room temperature. The resulting Pd@N-L3PR-50% catalyst achieved approximately 100% vanillin conversion and 97.91% selectivity for 2-methoxy-4-methylphenol at 80 °C with excellent cycle stability and adaptability to lignin-derived aldehydes, benefiting from the stable Pd-N coordination and the good adsorption capacity provided by the N-L3PR-50% support.

  @article{ , abstract = {Membranes integrating 1D materials are rapidly emerging as highly promising platforms for osmotic energy harvesting.

Herein, we demonstrate a cation pumping strategy by designing mesoporous silica coated multiwalled carbon nanotubes/aramid nanofiber (MCNTs@mSiO 2 /ANF) composite membranes as osmotic power generators. Cations can be initially enriched in the negatively charged and small-pore-sized (∼ 3 nm) interfacial mesopore channels, establishing a strong cation concentration gradient toward the interfiber nanochannels. The gradient continuously drives cations into the interfiber pores, facilitating charge separation, and improving ion selectivity. Additionally, the hydrophilic nature of the mesoporous silica shells promotes ion transport and contributes to high ion flux. Consequently, the fabricated MCNTs@mSiO 2 /ANF composite nanochannel membranes can deliver a notable power density of 8.24 W m −2 with an excellent ion selectivity of 0.91 under a 50-fold NaCl salinity gradient. Importantly, the membranes demonstrate long-term stability for osmotic energy capturing.

The following in vitro test using two Roseburia species belonging to this family validated labeling by the probe. We then discovered that the labeling site is the first amino acid (L-alanine in most bacteria), which links the stem peptide with N -acetylmuramic acid, a process catalyzed by a highly conserved enzyme MurC. An enzyme assay of Roseburia MurC demonstrated its ability to conjugate a fluorescent L-amino acid and other non-L-Ala amino acids to UDP- N -acetylmuramic acid. Subsequent X-ray crystallography analysis uncovered a substantially enlarged inner space in this enzyme, which can partially explain its tolerance to these atypical substrates.

Here, we observe the transition of p-type to n-type characteristics in a perovskite layer via buried interface engineering. The perfluorinated copper phthalocyanine (F 16 CuPc) molecules with strong electronegativity are employed to modify the NiO x /Me-2PACz substrate, which not only facilitates the crystallization of the perovskite, but also induces the formation of p-type perovskite at its buried interface. We observe a gradual shift of the Fermi level from near valence band at the perovskite buried interface to near conduction band at the perovskite top surface, manifesting the transition from p-type to n-type within the monolithic perovskite layer.

In this study, two isomeric donor–acceptor–donor (D–A–D) type small molecules, namely HBT and HiBT, were developed and used as dopant-free HTMs, using 2,1,3-benzothiadiazole or benzo[ d ][1,2,3]thiadiazole as acceptor moieties.

By analyzing this process experimentally and theoretically, we show that surface chemical speciation (oxidation-driven generation and self-organization of different species of the alloy components) in core-shell particles (CSPs) can perturb the entropy production to an extent that a continuum equilibrium phase transition is not possible. Speciation of the surface causes divergence of associated stress vectors that generate nonequilibrium fluxes and frustrates homogeneous nucleation hence deep undercooling. The asymmetry of the speciation-derived surface tensor skews the minimum entropy production criterion. We analyze a set of nonequilibrium models, one showing and one averting the entropy catastrophe. Applying thermodynamic speed limits to these models, we show that the KP takes another form.

We show that the solution pH can be precisely controlled by choice of illumination wavelength and intensity, and sufficient protons are released from the photoacid to achieve meaningful pH change in samples where the molecule of interest has significant buffering capacity, such as a >100 µM protein sample. The pH is monitored in situ using internal standards with pH-sensitive chemical shifts. This method enables precise, calibrated, and noninvasive change of sample pH within an NMR magnet, dramatically reducing the necessary sample handling. These findings highlight the potential of light-induced pH control in NMR experiments and increase the robustness and reliability of pH-dependent studies.}, archive = {J_ANGEW}, author = {Aarav Barde and Ruixian Han and Martin A.

The intermediate chiral trans -isomer was detected by step-scan FTIR, displaying a lifetime of 130 µs (r.t., CH 2 Cl 2 ). Ensuing Diels–Alder reactions of the trans -isomer occurred smoothly and produced chiral trans -fused cycloaddition products (14 examples, 24%–98% yield). Benzylation led to esters, which were separated by chiral HPLC and which were employed to evaluate a possible enantioselective reaction course. It was discovered that a chiral phosphoric acid with a pendant sensitizing group induces a notable enantioselectivity in the photoisomerization step. The planar chirality of the trans -cycloheptene translates into point chirality in the Diels–Alder reaction (seven examples, up to 38% ee ). Computational studies suggest that the chiral conformation of the cis -isomer adopted within the assembly to the chiral phosphoric acid induces the enantioselectivity in a one-bond flip (OBF) toward the trans -isomer. Trajectory surface hopping (TSH) simulations showed exemplarily how a chiral trans -cyclohept-2-enone is formed from a chiral cis -conformer.

The concentrations of these substrates often fall below the threshold for direct detection. The 3 ¹P CEST technique amplifies their responses, making them detectable via the ST effect to the 3 ¹P resonance of the selected reference signal. The method was first validated in vitro on mouse breast adenocarcinoma cell pellets (TS/A), where the intracellular Pi signal was monitored to assess the ST effect associated with the saturation of phosphoester-containing molecules. The use of a glycolysis inhibitor and different experimental temperatures (37 °C or 4 °C) provided insights supporting the rationale behind the method.

The promising strategy of selective molecular interaction would balance the crystallization rate.

Herein, we take advantage of thermodynamics and molecular orbital theory to reveal the competitive coordination of additive, i.e., methyl 5-aminolevulinate hydrochloride (5-AH), with SnI 2 and PbI 2 . The SnI 2 competes with PbI 2 in coordinating with 5-AH to form the thermodynamically favored SnI 2 -5-AH adducts with stronger SnI 2 -Cl − , thereby mediating the crystallization rate of the Sn- and Pb-based perovskite. Such crystallization regulation improves the composition uniformity and crystallization quality, which effectively suppresses nonradiative recombination. Additionally, the strong interaction between Sn 2+ and 5-AH as well as reductive grain boundaries inhibits the oxidation of Sn 2+ .

Herein, we investigate the effects of HO*/O* poisoning and H* coverage on SACs with varied metal centers and coordination environments using pH-dependent surface Pourbaix diagrams at the reversible hydrogen electrode (RHE) scale and microkinetic modeling. Our findings reveal that HO* poisoning, realistic H* adsorption strengths at active metal sites, and the potential HER activity at the coordinating N-sites are crucial factors that should be considered for accurate descriptor development. Experimental validation using a series of M-phthalocyanine/CNT catalysts (M = Co, Ni, Cu) confirms the theoretical predictions, with excellent agreement in exchange current densities and the role of N-sites in Ni/Cu-phthalocyanine/CNT catalysts. This work provides answers to a long-lasting debate on HER descriptors by establishing Δ G H* and Δ G HO* as a combined HER descriptor for SACs, offering new guidelines for catalyst design.}, archive = {J_ANGEW}, author = {Songbo Ye and Fangzhou Liu and Fangxin She and Jiaxiang Chen and Di Zhang and Akichika Kumatani and Hitoshi Shiku and Li Wei and Hao Li}, doi = {10.1002/anie.202425402}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {23}, pages = {e202425402}, shortjournal = {Angew.

  @article{ , abstract = {Composite solid electrolytes (CSEs) are promising candidates for solid-state lithium metal batteries. However, the poor cross-phase Li + transport restricts the rate performance and cycle life of the batteries. Herein, we revealed the Li + percolation behavior in poly(vinylidene fluoride) (PVDF)-based CSEs with Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 filler. The de-coordination barrier from Li + clusters determines interfacial Li + transport capability. We then employed a designed N -methyl-2,2,2-trifluoroacetamide (NMTFA) ligand to lower the de-coordination energy and activate interfacial Li + exchange. The ionic conductivity is therefore increased from 3.32 × 10 −4 to 7.30 × 10 −4 S cm −1 . By tracking the 6 Li and 7 Li substitution process, it was identified that the proportion of interfacial Li + transport increases from 11% to 26%. The NMTFA also contributes to the formation of inorganic-rich interphases with electrodes. As a result, the Li||LiNi 0.8 Co 0.1 Mn 0.1 O 2 solid-state batteries exhibit ultra-long lifespans of 2400, 3000, and 10 000 times at 2, 5, and 10C, respectively, as well as achieve 1000 cycles at 50 °C and 300 cycles at −30 °C.

  @article{ , abstract = {The passivation of detrimental perovskite-based defects is critically acknowledged for fabricating highly effective perovskite solar cells (PSCs). The presence of a high-quality electron transport layer (ETL) is also considered a pivotal factor for effective charge extraction and transport dynamics. Herein, a simple small organic molecule, aminomethyl phosphonic acid (AMPA), is introduced as a multifunctional additive in the SnO 2 ETL. The defects in the SnO 2 ETL are effectively suppressed by passivating the oxygen vacancies upon the SnO 2 surface. Simultaneously, the carrier mobility and crystallinity of SnO 2 are enhanced, and the upward-regulated conduction band minimum (CBM) is beneficial for constructing a favorable energy level alignment with the perovskite layer. Notably, the introduced residuals on the SnO 2 surface can function as crystalline seeds for growth of large perovskite grains, which can passivate the defects in the perovskite bulk phase, boundaries, as well as the SnO 2 /perovskite interface. Consequently, the power conversion efficiency ( PCE ) value of the AMPA-modified PSCs is enhanced from 19.91% to 24.22%. Most importantly, the unencapsulated PSCs with AMPA maintained 94.9% of the initial PCE during 720 h of storage at a relative humidity of 10%, attributed to the improved hydrophobicity of both the SnO 2 and perovskite layers after AMPA modification.}, archive = {J_ANGEW}, author = {Yujie Gao and Wenyu Gong and Zeqi Zhang and Jianing Guo and Jingyuan Ma and Xuan Li and Yanli Zeng and Mingxing Wu}, doi = {10.1002/anie.202424479}, journal = {Angewandte Chemie International Edition}, month = {6}, number = {23}, pages = {e202424479}, shortjournal = {Angew.

Furthermore, the high hydrophobicity of the auxiliary coordinated ligands (trialkylphosphines) to Ni center, particularly tributylphosphine, creates a nanoconfined space that enhances both the accessibility of CO 2 and the utilization of Ni II catalytic active sites while inhibiting hydrogen evolution.

  @article{ , abstract = {Strong metal-support interaction (SMSI) can be normally induced by the surface free energy differences between metal nanoparticles and supports. To gain deeper insights into the effect of SMSI on heterogeneous catalysis, we use prototype Pt, Pd/TiO 2 (anatase) systems to demonstrate different reverse water gas shift (RWGS) reaction activity changes, especially with increasing the metal nanoparticle (NP) loading. Our experiments show that the conventional surface-free-energy change law regarding the incremental NP size is no longer applicable to these systems due to the overlook of the change of support properties owing to the disparities of the metal anchoring mechanisms. Both experimental measurements and density functional theory (DFT) calculations show that Pt atoms strongly favor anchoring on the oxygen vacancies (O v ) over the OH-sites on the anatase TiO 2 support. In contrast, Pd atoms lack such O v -site preference compared to Pt atoms, thereby leaving higher content of O v on the support than the Pt counterpart. Moreover, high density of residual O v on the support can cause the Pd NPs to be in higher degree of contact with the support, either in NP-encapsulation state (experiment) or NP-spreading state (simulation). The enhanced CO 2 conversion of Pt/TiO 2 A is attributed to the synergistic effect of O v and hydrogen spillover from Pt sites.}, archive = {J_ANGEW}, author = {Yuxuan Xie and Xiongyi Liang and Zhao Li and Biao Zhou and Ping Ning and Xin Sun and Kai Li and Ken-ichi Shimizu and Xiao Cheng Zeng and Fei Wang}, doi = {10.1002/anie.202505820}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {22}, pages = {e202505820}, shortjournal = {Angew.

  @article{ , abstract = {Benzylic and allylic electrophiles are well known to react faster in S N 2 reactions than aliphatic electrophiles, but the origins of this enhanced reactivity are still being debated. Galabov, Wu, and Allen recently proposed that electrostatic interactions in the transition state between the nucleophile (Nu) and the sp 2 carbon (C2) adjacent to the electrophilic carbon (C1) play a key role. To test this secondary electrostatic hypothesis, molecular rotors were designed that form similar through-space electrostatic interactions with C2 in their bond rotation transition states without forming bonds to C1. This largely eliminates the alternative explanation of stabilizing conjugation effects between C1 and C2 in the transition state. The rotor barriers were strongly correlated with the experimentally measured S N 2 free energy. Notably, rotors where C2 was sp 2 or sp-hybridized had barriers that were consistently 0.5–2.0 kcal mol −1 lower than those for rotors where C2 was sp 3 -hybridized. Computational studies of atomic charges were consistent with the formation of stabilizing secondary electrostatic interactions. Further confirmation came from observing the benzylic effect in rotors where the first atom was varied, including oxygen, sulfur, nitrogen, and sp 2 -carbon. In summary, these studies provided strong experimental support for the role of secondary electrostatic interactions in the S N 2 reaction.}, archive = {J_ANGEW}, author = {Binzhou Lin and Hao Liu and Xiaolong Huang and Harrison M.

In this study, we employed a Cu 2+ -loaded metalized porphyrin-based covalent organic framework (Cu-Por-COF) as a conductive porous layer (CPL) at the perovskite bottom interface. Experimental results showed that a Cu-Por-COF coverage of 19% significantly enhanced electron transport and effectively suppressed long-distance electron diffusion. Moreover, the carefully designed Cu-Por-COF provided abundant active sites, which improved the film-forming quality of the perovskite layer, thereby facilitating the beneficial synergy of electron injection and defect passivation.

Theoretical calculations have demonstrated that the cascaded metalation with the introduction of secondary Ni sites not only strengthens * CO adsorption but also accelerates proton generation for the hydrogenation of *CO toward CH 3 OH.

This study introduces a novel structural design that enables precise control of both the mode and amplitude of deformation. This design integrates photo-reactive o -nitrobenzyl moieties and temperature-dependent hydrogen bonds into the LCE structure. The o -nitrobenzyl moieties enable irreversible reconfiguration of the LCE crosslinked network through photoreactions, allowing for easy alignment and reshaping of the material. Meanwhile, the hydrogen bonds act as “temperature-dependent locks”, regulating the mobility of polymer chains during thermal deformation. By adjusting the heating temperature, the deformation amplitude can be finely tuned across a wide range (0%–103%). The synergy of these two mechanisms—light-induced irreversible reconfiguration and temperature-induced reversible H-bond exchanges—empowers LCEs to achieve customizable and continuous deformations.

Upon activation by APN, ANA- o -BODIPY produces a reactive intermediate, aza-quinone methide, which covalently binds to proximal proteins.

To circumvent these problems, transition-metal complexes (e.g., Cu 2+ and Ni 2+ ) were intercalated in 2D perovskites and reported, for the first time, the photoluminescence (PL) profiles. 2D perovskites incorporating transition-metal complexes can be considered a molecular “type II” heterostructure where the “conduction band” is localized on the complexes and the “valence band” on the haloplumbate layers. As evident in the absorption and PL spectra of the materials, the “type II” configuration allows inter-band transitions to occur in addition to intraband within 2D Pb─Br layers. This makes the material's PL excitation wavelength dependent, allowing activation of only inter-band or inter-band plus intraband transitions by certain wavelengths.

Although benzannulation has been used successfully as a structural constraint to control the excited state properties, fusion of the N-aryl groups to the phenazine backbone has rarely been explored. Herein, we report the first examples of dihydrophenazines, in which the N-aryl groups are fused to the phenazine backbone via B←N Lewis pair formation.

The redox-active piperazine units enable to storage electrons, thus accelerate the electron transfer to the catalytic sites. Furthermore, the introduction of ─OH group-containing building blocks induces keto-enol tautomerism (enabling reversible ─OH / ─C═O interconversion), improving framework polarity with a dipole moment of 6.87 Debye (5.8 times increase compared to non-hydroxylated COFs).

  @article{ , abstract = {Rechargeable magnesium (Mg) batteries represent a promising energy storage system by offering low cost and dendrite-less propensity. However, the limited selection of cathode materials, and often with low voltage and capacity, constrain Mg batteries. Herein, by exploiting the ion-docking effect between two halogen species—iodine cations (I + ) and chlorine anions (Cl − )—we activate the cathodic activity of halogens and develop a magnesium–iodine/chlorine (Mg-I/Cl) battery prototype with high energy and power density. The ion-docking effect enables I + and Cl − to mutually balance and disperse their charges, and weakens the coordination strength between Cl − and Mg 2+ while enhancing the stability of I + , thus facilitating the multi-electron (2 + 1/3) redox reactions of halogens. We also find the solvation state of iodine species determines the reaction process of the I 0 /I 3 − /I − redox couples. The here-developed magnesium–iodine/chlorine battery features an impressively high discharge plateau of up to 3.0 V with a high capacity exceeding 400 mAh g −1 , and demonstrates a stable lifespan for 500 cycles, with the ability of ultra-fast charging at 20C and low-temperature cycling under −30 °C.

Fullerene derivatives, such as PCBM, are widely employed ETL materials in PSCs due to their excellent electron affinity and energy level alignment with the perovskite layer. However, PCBM suffers from high energy disorder, self-aggregation predilection, and insufficient defect passivation ability, leading to significant charge carrier recombination and accumulation at interfaces. Herein, a phosphate-substituted fullerene derivative, FuPE, is developed to enhance the performance of PCBM-based ETLs for PSCs. Incorporating FuPE efficiently compacts molecular stacking, enforces crystallinity and intermolecular interaction, suppresses self-aggregation, and improves interfacial compatibility of the FuPE:PCBM blend. Such endows the FuPE:PCBM blend film with enhanced electron mobility (0.183 cm 2 V −1 s −1 ), lower trap density, more uniform film morphology, and superior defect-passivation ability, compared to the PCBM pristine one.

In this work, the cell polarization of DES is effectively reduced to a level comparable to that of pure aqueous electrolytes by increasing the entropy of DES via the disorder-making strategy of solvation structure. Theoretically, constructing the high-entropy deep eutectic solvent (HEDES) promotes the formation of more aggregates with high disorder, which accelerates mass transfer kinetics. As a result, the proposed HEDES (configuration entropy 17 times higher than traditional electrolyte) can achieve durable zinc plating/stripping behavior for more than 2000 h with low polarization and still maintain good stability even in extreme environments. The cylindrical zinc-ion capacitor under gram-level loading can achieve a high discharge current up to 3 A, providing ideas for the design of electrolytes for zinc-based energy storage devices.}, archive = {J_ANGEW}, author = {Nengze Wang and Ming Zhang and Xiaohe Ren and Mengxuan Sun and Tianning Pian and Pinji Wang and Yang-feng Cui and Xiaojun Yao and Chunyang Jia and Hui Ying Yang}, doi = {10.1002/anie.202502761}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {22}, pages = {e202502761}, shortjournal = {Angew.

  @article{ , abstract = {The serious voltage hysteresis phenomenon in Na 3 MnTi(PO 4 ) 3 has received extensive research interests, which is determined by the intrinsic-antisite-defects (IASDs) of Mn 2+ resided in Na vacancies (Mn/Na □ ) in structure. However, a general guideline to decrease IASDs is still lacking for the design of a higher-performance Na 3 MnTi(PO 4 ) 3 system. Herein, we find that generation of Mn/Na□ IASDs in Na 3 MnTi(PO 4 ) 3 system is mainly related to Na vacancies and weaker Mn─O bonds in structure. The more Na vacancies, the more probability for Mn 2+ occupation on Na sites. Meanwhile, the weaker Mn─O bond, the more probability for Mn 2+ delocalization/migration to other sites, finally leading to the Mn/Na □ IASDs. To decrease Mn/Na □ IASDs, we propose to introduce dopants with lower valence (vs. Ti 4+ ), lower electronegativity (vs. Ti 4+ ), and good solid solubility in Na 3 MnTi(PO 4 ) 3 system. Based on the guiding rule, we have selected several doping cations (including Cr 3+ , Ti 3+ , Fe 3+ , and V 3+ ) to construct a Na-rich environment and enhance Mn─O strength. Among various dopants, the substitution of V 3+ for Ti 4+ leads to the strongest Mn–O interaction, thus demonstrating the most effective suppression of Mn/Na □ IASDs.

It is worth noted that the change of group IVB elements in Bi 8 M 7 -TBC4A can specifically modulate the LUMO-HOMO orbitals to distribute on different active metal atoms. This allows it to be an excellent model system to verify the effect of the transport paths of photogenerated charges on photoreactivity.

Endogenous gasotransmitters, such as carbon monoxide (CO) and hydrogen sulfide (H₂S), exhibit potent anti-inflammatory and immunomodulatory effects. However, their therapeutic application is limited by challenges in targeted delivery to affected tissues. Here, we propose a novel strategy for targeted gut delivery of CO/H 2 S through engineering Escherichia coli Nissle 1917 (EcN) with CO/H 2 S-releasing copolymer (POSR) loading. This engineered probiotic (POSR@EcN) enhances EcN colonization in the intestine and enables controlled, localized release of CO/H 2 S at inflamed sites. The release of CO/H 2 S modulates inflammation, restores intestinal barrier integrity, and reshapes gut microbiota by promoting beneficial bacteria and increasing short-chain fatty acids production, effectively alleviating IBD symptoms. Notably, targeted CO/H 2 S delivery also elevates neuroprotective metabolites like indoleacetic acid and γ-aminobutyric acid, reducing neuroinflammation via the gut-brain axis and mitigating anxiety- and depression-like behaviors in IBD mice.

Optical studies initially probed the symmetry-breaking charge separation events in these dimers wherein solvent polarity-dependent quenching was witnessed.

Free-energy calculations supported symmetry-breaking charge separation in polar solvents and the ortho dimer even in nonpolar solvents under isoenergetic (endothermic by ∼40 mV) conditions. Molecular electrostatic potential maps generated on DFT-optimized structures revealed quadrupolar charge transfer states, more so in polar media. The time-dependent DFT calculations revealed the conversion of the quadrupolar charge transfer states to bipolar charge-separated states from different singlet–singlet excitations. Femtosecond transient absorption studies covering broad temporal and spatial scales provided evidence for the charge separation process, including that for the ortho dimer in toluene, where an isoenergetic process was predicted.

By functionalizing the azobenzene ring, we showed that the responsiveness of the system is maintained in seven distinct AODs.

An activatable afterglow probe (i.e., BDIS-NPs) is fabricated, which can simultaneously activate fluorescence and afterglow signals in the presence of hydrogen disulfide (H 2 S). Owing to the elimination of autofluorescence and high activation contrast of the afterglow signal, BDIS-NPs enables early monitoring of lipopolysaccharide (LPS)-induced acute lung injury within 15 min and sensitive visualization of H 2 S accumulation in the brain of schizophrenia mice with a high signal-to-background ratio (SBR), which is not achievable by fluorescence imaging.

  @article{ , abstract = {In conventional electrodes, concentration polarization by unbalanced charge transport and solid-state diffusion resistance result in sluggish reaction kinetics, hindering the practical application of zinc-ion batteries. Here, we propose an integrated mixed electronic–ionic conductor by spatially coupling charge transport pathways, which could achieve redistribution and fast transport of charge (Zn 2+ /e − ). Operando electrochemical quartz crystal microbalance and electrochemical impedance spectroscopy revealed the charge transport mechanisms and intrinsic conducting characteristics at timescale. Through confinement by vanadium oxide, dual-conductive pathways were self-assembled at the nanoscale and provided effective charge storage. This provided high charge density and accelerated ionic diffusion in the bulk phase, resulting in more active sites and faster reaction kinetics. Moreover, reversible ionic channels from the self-doping/de-doping process reduced the dissolution of active materials by protons and enabled conversion chemistry, improving cycling stability at low current density. Consequently, the modulated cathode (PEDOT-SO 3 -ZnVO) delivered a high-rate performance of 310/148 mAh g −1 (0.2/10 A g −1 ) at 10 mg cm −2 . Importantly, the conventional electrode at 21 mg cm −2 achieved an ultra-high areal capacity of 6.0 mAh cm −2 and superior cycling stability (79.1% retention over 100 cycles at 0.2 A g −1 ).

Among these six cationic surfactants we identified a prime candidate, which possessed an impressive antibacterial effect against gram-positive and gram-negative bacteria, including drug-resistant strains.

  @article{ , abstract = {Fabricating high-quality perovskite layers is essential for achieving high-performance solar cells. Considering the significant advancements made in additive engineering for optimizing perovskite crystallization using single additive, exploring the collaborative effect of dual additives on precursor for perovskite crystallization may be an effective way for further advancing device performance. Herein, a binary additives strategy is proposed, where phenylmethylammonium iodide (PMAI) and [2-(9 H -carbazol-9-yl)ethyl]phosphonic acid (2PACz) are introduced into the precursor. Compared with the precursor with no additives or a single additive (PMAI or 2PACz), the use of dual additives more effectively cleaves edge-shared Pb-I octahedra to expedite the transformation from PbI 2 to PbI 3 − complexes as prenucleation clusters and produces much larger colloidal particles with accelerated nucleation. Concurrently, the crystallization in both spin-coating and annealing processes is significantly retarded due to the stronger interaction between perovskite and binary additives. Benefiting from such rapid nucleation and slow crystallization, high-quality perovskite layer with larger-sized crystals and fewer defects is formed, resulting in mitigated microstrain, enhanced charge extraction, and suppressed nonradiative recombination.

  @article{ , abstract = {Hollow multi-shell covalent organic frameworks (COFs) with abundant modular interfaces, high loading capacity, and various microenvironments are expected to hold great potential for chemical separation, heterogeneous catalysis, and energy storage/conversion. However, the synthetic methodology of COF hollow multi-shell nanoarchitectures has not been established. Herein, we demonstrate an ingenious “crystallinity wave”-induced regional difference ripening strategy to synthesize a series of hollow multi-shell COF particles with controllable shell numbers and shell thickness. The methodology relies on the isolation effect of the local crystalline COF thin layer inserted between the two layers of amorphous covalent organic polymer by the short-time Ostwald ripening, so that different regions of the particles exhibit distinct reaction stages before reaching chemical equilibrium in the subsequent dynamic imine exchange reaction, and then regions that tend to hydrolyze dissolve during the complete ripening process to form a hollow multi-shell structure. Remarkably, this strategy can be extended to prepare other hollow multi-shell COFs by altering monomers. As a proof-of-concept application, the obtained hollow multi-shell COFs are used as the electrode materials for supercapacitor. Benefiting from the short mass transfer path of the hollow multi-shell structure, ordered channels of the COF, and their high surface area, the as-prepared particles exhibit remarkably enhanced specific capacitance.}, archive = {J_ANGEW}, author = {Yuanbo Sun and Bin Zhao and Ji Han and Guangrui Chen and Ruigang Sun and Chengyue Yang and Zhaohui Shi and Bohan Liu and Wenbin Tu and Shanshan Li and Benzheng Li and Guiyuan Zhong and Song Lin Zhang and Wei Feng and Dan Wang and Buyuan Guan}, doi = {10.1002/anie.202423088}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {22}, pages = {e202423088}, shortjournal = {Angew.

  @article{ , abstract = {Precise modulation of dynamic and complex tumor microenvironment (TME) to disrupt tumorigenesis and reshape intratumoral immune infiltration has emerged as promising approaches for enhanced cancer therapy. Among recent innovations, proteolysis-targeting chimeras (PROTACs) represent a burgeoning chemical knockdown technology capable of degrading oncogenic protein homeostasis and inducing dynamic alternations within carcinoma settings, offering potential for antitumor manipulation. However, achieving selectivity in PROTACs that respond to disease environmental stimulation and precisely perturb on-target proteins remains challenging. The multi-step synthesis and limited permeability, attributed to high-molecular-weight and heterobifunctional structures, further hinder their in vivo efficacy. Herein, we present a unique TME-responsive enzyme-activated clickable PROTACs, which features a short peptide-tagged pomalidomide derivative to undergo tumor-specific cleavage by cathepsin protease to induce orthogonal crosslinking of the exposed cysteine with 2-cyanobenzothiazole-labeled epigenetic protein-ligand JQ1, facilitating in situ degrader formation within tumor regions only. Systematic protein profiling and proteomic analysis revealed that such TME-specific clickable-PROTACs not only selectively eliminate epigenetic proteins without tedious pre-synthesis to bridge disparate small-molecule bi-warhead fragments, but also demonstrated superior tumor penetration compared to conventional high-molecular-weight PROTACs. Importantly, these clickable-PROTACs efficiently downregulated immune checkpoint programmed death-ligand 1 (PD−L1) both in vitro and in vivo, remodeling TME for enhanced therapeutics, especially in anti-tumoral immunomodulation.}, archive = {J_ANGEW}, author = {Caixia Sun and Songhan Liu and Jun Wei Lau and Hanyu Yang and Yun Chen and Bengang Xing}, doi = {10.1002/anie.202423057}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {22}, pages = {e202423057}, shortjournal = {Angew.

The “Four-in-One” surface chemistry enables various single-crystal-to-single-crystal (SC-SC) structural transformations, involving ligand modification, cation exchange, post-synthetic metalation, and metal elimination, successfully achieving the first reversible SC-SC transformation from cluster structures to infinite frameworks. The fundamental reason behind these dynamic structural changes lies in the exceptional balance between rigidity and flexibility provided by the intercluster tri-pyrazole sites on the Archimedean cages. This diverse structural transformation characteristic offers extensive application potential for solid-liquid and solid-gas serial adsorption.

A unique puckered rather than planar conformation of central core is adopted, caused by the 4n πe − feature, great ring strain and largely the insufficient p–π orbital overlap of lone pair on sulfur of thianthrene and coterminous benzene planes. As a result, the absorption of thianthrene-based acceptors (CS1, CS2, and CS3) shows unexpected blue shift comparing to the phenazine-based counterpart (CH20), regardless of the intrinsically strong electron-donating characteristic of low valence sulfur atoms.

Blue quantum dots (QDs) with giant CdZnSeS alloy cores are expected to improve the internal confinement of excitons due to the nonmonotonical energy landscape of their conduction band, while they haven't shown high performance in QLEDs due to insufficient optimization of their shell structures. In this work, giant CdZnSeS alloy cores were synthesized by diffusing Zn atoms into CdSeS cores, so that the core/shell lattice stress was released due to the optimized gradient compositions. As a result, exciton transfer and Auger recombination are both suppressed, leading to a breakthrough external quantum efficiency (EQE) of 24% in blue QLEDs with giant CdZnSeS alloy cores. Compared to the more extensively studied blue quantum dots with CdSeZn alloy cores, blue QLEDs with giant CdZnSeS alloy cores also benefit from the suppressed Fermi level and nonmonotonical energy landscape of the conduction band minimum (CBM), which are crucial for confining the wavefunctions of the excitons.

Single-molecule techniques enable real-time tracking of stereochemical transformations. These techniques include electrical methods (such as scanning probe microscopy, single-molecule junction techniques, and nanopore technology) and non-electrical approaches (such as circular dichroism spectroscopy and surface-enhanced Raman spectroscopy). This review highlights recent advances in monitoring and regulation of stereochemical properties at the single-molecule level.

Key isomerization phenomena (constitutional, configurational, and conformational isomerizations) are explored to demonstrate how light, electric field, and mechanical force regulate molecular states. The use of chiral molecules in optical tweezers, chiral-modified scanning tunneling microscopies, and graphene-based single-molecule junctions to leverage the chirality-induced spin selectivity effect for enantiomer discrimination and manipulation is highlighted. Despite progress in this field, challenges persist in resolving ultrafast isomerization pathways, understanding chiral origin mechanisms, and integrating single-molecule devices.

  @article{ , abstract = {Fluorescence super-resolution microscopy has enabled nanoscale imaging of intracellular structures, but it remains challenging to simultaneously achieve structural imaging and quantitative functional characterization, such as pH measurement, within the same region. Here, we introduce two-color single-molecule blinking ratiometricity (2C-SMBR), a novel method that integrates structural and functional imaging with single-molecule precision. By loading lysosomes with two pH-dependent spontaneously blinking fluorophores of distinct colors, 2C-SMBR leverages single-molecule localization of either fluorophore to achieve nanoscale structural imaging of lysosomes, whereas the ratiometric analysis of blinking dynamics between the two fluorophores provides quantitative pH measurement at the single-lysosome level. This dual-color ratiometric approach at the single-molecule level enables precise quantification of lysosomal pH with exceptional spatiotemporal resolution. Using 2C-SMBR, we reveal that lysosomal pH is highly heterogeneous at the single-lysosome level, with distinct subpopulations exhibiting diverse pH values. Our measurements show a pH range of 4.0–6.0 within lysosomes, with perinuclear lysosomes averaging a pH of approximately 4.88, whereas peripheral lysosomes average around 5.64. Crucially, 2C-SMBR enables real-time correlation between lysosomal dynamics and pH changes, overcoming a key limitation of super-resolution imaging.

  @article{ , abstract = {Nanovaccines hold significant promise for the prevention and treatment of infectious diseases. However, the efficacy of many nanovaccines is often limited by inadequate stimulation of both innate and adaptive immune responses. Herein, we explore a rational vaccine strategy aimed at modulating innate cell microenvironments within lymph nodes (LNs) to enhance the generation of effective immune responses. Inspired by the structure and natural infection process of viruses, we developed a versatile antigen and adjuvant co-delivery platform, termed virus-mimetic vaccines (VMVs). Specifically, polyarginine-tagged antigens were noncovalently assembled onto nucleic acid nanogels containing cytosine-phosphate-guanine oligodeoxynucleotide via a salt-bridge zipper mechanism, which can activate Toll-like receptor 9. Upon intramuscular immunization, VMVs effectively drained into the LNs, recruiting and activating multiple innate cells, including CD8 + dendritic cells (DCs), CD103 + DCs, macrophages, plasmacytoid DCs, and neutrophils. This activation modulates the innate cell microenvironments and relocates antigen-presenting cells within LNs, optimizing adaptive immune responses. VMVs induced a robust antigen-specific immune response, characterized by high levels of neutralizing antibodies, augmented memory T cell activity, and enhanced development of germinal center B cells. Together, our findings demonstrate that dynamic modulation of innate cell microenvironments by VMVs leads to optimized generation of both humoral and cellular immunity against infectious diseases.}, archive = {J_ANGEW}, author = {Runping Su and Tingting Yao and Chong Cao and Yaqi Yang and Mingshan Chen and Jianxiao Wu and Yue Zhao and Xiaoxiao Liu and Sha Li and Junqiang Ding and Rong Yang and Shun Shen and Chuan Zhang and Changyou Zhan and Xihui Gao}, doi = {10.1002/anie.202503845}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {21}, pages = {e202503845}, shortjournal = {Angew.

  @article{ , abstract = {Non-canonical DNA junction structures are important in human disease and in nucleic acid nanoscience and there is a growing interest in how to bind and modulate them. A key next step is to exert “on command” control over such binding.

This inactive cylinder bears six flexible arms each with a quinone group at the termini. Reduction by the enzyme leads to all six arms being removed, transforming the inert cylinder into a new and active metallo-supramolecular agent that binds junctions. This gives the ability to “switch-on” DNA junction formation and binding in response to the presence of two external stimuli – a human enzyme overexpressed in many disease states, and NADPH – and absence of inhibitor, giving NAND logic control. Modelling indicates the binding activation originates not in steric unblocking but changes in conformational flexibility.

  @article{ , abstract = {Tailored syntheses of non-centrosymmetric (NCS) second-order nonlinear optical (NLO) crystals, particularly those of metastable NCS polymorphs, remain extremely challenging due to the complex interactions of their constituent primitives. In this work, we report the first successful synthesis of a set of three nitrate supramolecular polymorphs (C 2 H 5 N 4 )(NO 3 ) (α-, β-, and γ-phases) by a pH-modulation secondary-bond strategy, via the assembly of two types of π-conjugated planar primitives. Solutions of different pH result in differing orientation of secondary bonds between [C 2 H 5 N 4 ] and [NO 3 ] primitives. Secondary bonds dominate the packing of primitives in crystal lattices; varying these secondary bonds can afford NCS or centrosymmetric nitrate supramolecular polymorphs, with 2D α-phase irreversibly transformed to 2D β-phase in a solution of appropriate pH. These two polymorphs display distinctly different SHG responses and birefringences, ascribed to variation in stacking of 2D hydrogen-bond layers resulting from the differing environmental pH. Supramolecular crystal structures comparison and theoretical studies confirm the crucial role played by secondary-bond interactions between adjacent primitives in the rare nitrate supramolecular polymorphs.

The key to overcoming these long-term obstacles lies in the rational design of the Li + solvation-desolvation behavior in SPEs. Herein, we propose an electric-dipole coupling ion-dipole strategy to modulate the Li + solvation structure and enhance Li + desolvation kinetics. The experimental characterizations and theoretical calculations indicate that the free solvents and FSI − are anchored by ion–dipole interactions, which facilitate the transfer of Li + and obtain a wide electrochemical stability window. Coupling the electric-dipole interactions that promote lithium salt dissociation and rapid ion desolvation contributes to obtaining more mobile Li + and realizing an inorganic-rich electrolyte/electrode interface. Benefiting from the above benefits, the assembled lithium symmetric cells and the full cells demonstrate ultralong cycling life.

  @article{ , abstract = {Photosynthesis of hydrogen peroxide from earth-abundant water and air over organo-based semiconducting materials is a promising alternative to the traditional anthraquinone (AQ) method. However, the generally hydrophobic nature of organic semiconductors has led to their poor dispersibilities in aqueous systems, which built huge barriers for photon capture and reactant contact in water-based photocatalysis. Aiming at this issue, this study reports the facile synthesis of AQ-based porous aromatic frameworks (AQ-PAFs) by coupling AQ fragments with thiophene-derived linkers via robust carbon–carbon bonds. Remarkably, the interfacial hydrogen bonding interactions between water molecules and AQ sites on the surface improve the general hydrophilicity of AQ-PAFs, which can be well-dispersed in water-only systems with uniform particle size distributions. Moreover, the AQ moieties also function as mediators of photoinduced electrons, and the protons produced from water oxidation reaction (WOR), which would kinetically favor the charge separation and subsequent electron transfer reactions.

Here we suggest a new strategy for tuning and maximizing Δ E ST based on a detailed analysis of the underlying quantum mechanical energy terms. We present a model based on the transition density and derive three straightforward design rules: Δ E ST values can be maximized by (i) minimizing the overall number of π-electrons, (ii) reducing delocalization, and (iii) optimizing specific geometric interactions. The validity of these rules is first exemplified for a set of 18 hydrocarbon backbones before proceeding to a varied set of dye molecules, highlighting their transferability to realistic settings.

Tricyanofuran photoacids are synthesized with absorption maxima of varying wavelengths across the whole visible spectrum. Protons released by the photoacids upon selective irradiation reversibly mask the more basic receptor-bound ligand, leading to ligand exchange that can be observed as a shift in the circular dichroism (CD) spectrum of the reporter complex. A ≈90 nm separation between the absorbance maxima of the photoacids allowed each to be selectively photoisomerized in the presence of the other. The concentration of released protons, and hence the magnitude of the shift in CD response, are controlled by changing the wavelength of the incident visible light.

Chemically controlling the activity of potent cytokines could mitigate unwanted T cell stimulation and widen their therapeutic window. In this study, we developed a strategy for the conditional activation of proteins utilizing removable peptide nucleic acid (PNA) masking groups. Site-specific installation of “Lock”-PNAs containing a cleavage thioester linkage enabled steric blockage of receptor binding sites. Rapid unmasking and activation were performed by the addition of a complementary “Key”-PNA containing a cysteine (Cys) residue, which forms a PNA–PNA duplex leading to a proximity-accelerated cleavage step and release of the active protein. We exemplified the versatility of this methodology on de novo cytokine neoleukin-2/15 (Neo-2/15) through the preparation of PNA conjugates including homodimers, PNA-stapled conjugates, and dual PNA-bridged dimers. All constructs were effectively unmasked at low micromolar concentrations. Further, we demonstrated the conditional activation of a masked conjugate of Neo-2/15 in binding studies to the IL-2 receptors and in an ex vivo T cell signaling assay displaying a 480-fold potency increase upon activation.

  @article{ , abstract = {Defect passivation is widely acknowledged as a crucial strategy for enhancing the efficiency and stability of perovskite solar cells (PSCs). However, it remains a formidable challenge to effectively address multiple defects simultaneously on both the top and bottom surfaces of perovskite films, as well as within the bulk, through a facile method. To tackle this dilemma, we have devised a triple passivation strategy, aiming to achieve a holistic passivation of defects at the aforementioned locations using a singular passivator. Specifically, a multifunctional molecule, tris(2,2,2-trifluoroethyl) phosphate (TTFP), is meticulously engineered as an additive in the antisolvent. This approach capitalizes a top-down gradient distribution of TTFP along the perovskite film, thereby enabling to mitigate the interfacial and bulk defects. Meanwhile, the unique molecular structure of TTFP facilitates simultaneous interactions with both cationic and anionic defects. Additionally, TTFP exerts a pronounced influence on the crystallization kinetics, thereby promoting the formation of highly crystalline perovskite films with substantially enlarged grain sizes. Consequently, the TTFP-based devices exhibit a champion power conversion efficiency (PCE) of 25.69%, accompanied by a notable improvement in stability.

Typically, the incorporation of trivalent metal ions into titanium silicalite-1 (TS-1) framework can provide the two types of active centers, but this often results in decreased oxidative activity.

This synergistic interplay endows Li–O 2 batteries with a highly active and stable bidirectional self-regulating capability during the process of circulation, exhibiting an ultra-low charge polarization (0.42V) and exceptional cycling stability (1680 h). V o and Ru 1 synergistically modulate the d -band center at the Ti site to establish an adaptively tunable Ru–Ti dual-active site. This adjustment effectively balances the binding strength with the interface oxygen intermediate ( * O), thereby significantly reducing the activation barrier. The Hamiltonian layout further revealed the crucial role of remote orbital coupling in maintaining the structural stability. This study not only provides profound insights into V o -dependent electron transfer kinetics but also proposes new strategies and theoretical guidance for the activation of inert materials.}, archive = {J_ANGEW}, author = {Yaning Fu and Chunmei Liu and Lina Song and Shaoze Zhao and Mengyao Huang and Zhongjun Li and Huabiao Tang and Youcai Lu and Jijing Xu and Qingchao Liu}, doi = {10.1002/anie.202501837}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {21}, pages = {e202501837}, shortjournal = {Angew.

Here a unified platform is reported to achieve direct cyclization of unprotected oximes with enals, as well as other coupling partners through dual copper/organophotoredox catalysis under green light irradiation. This protocol enables concurrent activation of both N─OH and α -C(sp 3 )─H bonds of free oximes to form multisubstituted pyridines with exceeding structural diversity and functional group tolerance. In this process, Rose Bengal serves as a hydrogen atom transfer agent to generate radical intermediates. In the meanwhile, copper catalyst activates of free oximes via single-electron reduction-induced N─O bond fragmentation and controls the selectivity for intermediate trapping.

  @article{ , abstract = {Cells execute mesmerizing functions using supramolecular polymers (SPs) formed through the self-assembly of biological precursors. Integration of the vast array of synthetic SPs with living cells would offer a powerful way to remold cellular functions and bridge the gap between synthetic materials and the biological realm, yet remains a challenge because of the lack of robust abiotic SP systems that can be triggered to self-assemble inside cells. Here, we report how fully abiotic SPs can be synthesized inside living cells via an organocatalysis-responsive self-assembly strategy, and how the in situ-generated SPs are capable of interfering and can interfere with cellular functions. The incorporation of a nucleophilic organocatalyst ( CAT ) into living cells accelerates the intracellular conversion of hydrazide ( H ) and aldehyde-derived precursors ( A ) to hydrazone-based monomers ( HA 3 ) that locally self-assemble into SPs. Interestingly, the in situ-generated SPs possess ignorable effects on cell viability and proliferation but remarkably hinder cell migration. Furthermore, the presence of SPs is found to retard intracellular diffusion and alter the organization of the actin cytoskeleton, both of which are suggested to be responsible for the hindered cellular migration. In considering the vastly wide range of synthetic SPs, tremendous non-natural cellular functionalities can be obtained by in situ-synthesizing SPs.}, archive = {J_ANGEW}, author = {Hucheng Wang and Ya-Ting Zheng and Jiahao Zhang and Yuliang Gao and Jingjing Chen and Peiwen Cai and Junyou Wang and Jan H. van Esch and Xuhong Guo and Hui Li and Yiming Wang}, doi = {10.1002/anie.202500998}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {21}, pages = {e202500998}, shortjournal = {Angew.

Herein, we designed an anchor peptide-based immobilization strategy for Pickering emulsions to achieve efficient glycosylation of natural products by glycosyltransferases (GTs). Firstly, through enzyme mining, natural GTs were utilized to synthesize pharmaceutically important acacetin glucoside and galactoside. However, the best-performing enzymes, BacGT and BarGT-3, still showed low conversions for acacetin glucoside (<40%) and galactoside (<10%). Then, Spy chemistry was employed to cyclize these two GTs (Spy_BacGT and Spy_BarGT-3) for improved robustness, and a Pickering emulsion was formed with the free two Spy_GTs, using 20% 2-hexanone and 1% mesoporous silica nanoparticles (carriers of mesoporous, CM), achieving 70% and 66% conversions of acacetin glucoside and galactoside, respectively. Further immobilization of the cyclized GTs onto CM via the anchor peptide liquid chromatography peak I (LCI) (Spy_BacGT/BarGT-3_LCI@CM) further enabled the system to reach more than 90% conversions of acacetin glycosides, retaining 90% conversions after 6–8 cycles.

Here, an ultrathin, hydrophobic copper phosphate (CP) membrane is introduced that selectively masks active Zn sites with electrochemically inactive copper through a galvanic replacement reaction (Zn 0 + Cu 2+ = Cu 0 + Zn 2+ ). Copper is deliberately chosen for its higher redox potential (Cu 2+ /Cu 0 ; +0.34 V vs SHE), which effectively inhibits both the corrosion reaction (H + /H 2 ; 0 V vs SHE) and dendrite formation (Zn 2+ /Zn 0 ; −0.76 V vs SHE).

Applying a combination of tandem-mass spectrometry, quantum-chemical computations, and statistical rate-theory calculations, we find several different fragmentation reactions, among which the homolytic cleavage of metal-carbon bonds and radical dissociations are particularly prominent.

Specifically, the acidity/alkalinity and binding strength are preliminarily tuned using different functional groups of -PO₃H₂, -COOH, and -NH₂, and further finely adjusted by altering the chain lengths between the benzene ring and the functional groups. The results show that strong binding is indispensable for effectively suppressing voltage loss. However, the commonly used benzylphosphonic acid (BPPA) for firm surface binding exhibits too strong acidity that can etch the perovskite surface, resulting in halide-vacancy defects and pronounced hysteresis. Increasing the side chain length of BPPA to (2-phenylethyl)phosphonic acid not only enables a suitable acid dissociation constant (p K a) to avoid acid-induced etching but also achieves robust anchoring to the perovskite surface with a parallel adsorption orientation, which reduces the charge transport barrier at the interface.

Attractively, such a damaged catalyst and its active sites can be effectively regenerated by an in situ redox reaction followed by electrochemical oxidation through switching the anode into the different solutions, resulting in the full recovery of the OER activity to its initial value.

Here, we report the structural investigation of a class of lytic peptides that self-assemble into filamentous nanomaterials. CryoEM analysis was employed to determine the structure of one of the filaments, which revealed that the peptides are self-assembled into a bilayer nanotube, in which the interaction between layers of amphipathic α -helices was mediated through hydrophobic interactions. The relative stability of the filament peptide assemblies depended on the influence of sequence modifications on the helical conformation. Antimicrobial assays indicated that cytolytic activity was associated with dynamic disassociation of the filamentous assemblies under the assay conditions. Structural modifications of the peptides that stabilized the filaments abrogated lytic activity.

  @article{ , abstract = {Room-temperature sodium–sulfur (RT Na–S) batteries are garnering attention for large-scale energy storage. However, their practical application is hindered by challenges, such as the shuttle effect of sodium polysulfides (NaPS) and dendrite growth. The high solubility of NaPS in the electrolyte is particularly problematic. It disrupts electron transfer and obstructs mass transport in the electrical double layer (EDL) region. The EDL plays a pivotal role in governing the interfacial chemistry between the electrode and electrolyte, significantly impacting the overall electrochemical performance. Through simulations and experimental screening of various solvents, including 1,2-dimethoxyethane (DME), tetrahydrofuran (THF), and tetrahydropyran (THP), along with ethyl 1,1,2,2-tetrafluoroethyl ether (ETFE) as a diluent, the relationship between NaPS solvation structure and EDL chemistry has been elucidated. Our findings reveal that THP-based localized high-concentration electrolyte (LHCE) not only reduces the solubility of NaPS by altering its solvation structure but also promotes the formation of a stable inorganic solid-electrolyte interphase (SEI) and improves compatibility with sodium metal. Consequently, Na–S batteries with LHCE-THP/ETFE exhibit long-term stability over 500 cycles at 1C rate with a capacity decay rate of only 0.07% per cycle.

  @article{ , abstract = {Glyphosate ( N -phosphonomethyl glycine, GPh) is an industrial herbicide used worldwide in modern agricultural practices. With the growing concerns regarding cumulative environmental and health effects, pathways for catalytic GPh degradation to benign products are becoming a pressing societal need. This report demonstrates that Zr-based metal–organic framework (MOF-808) with different crystal sizes and designed defect sites can be employed as an efficient heterogeneous catalyst for the complete degradation of GPh at room temperature. Importantly, the degradation mechanism produces N -formyl glycine and hydroxymethyl-phosphonate, which are largely innocuous chemicals, especially when compared to more common GPh degradation products. Nanocrystalline MOF-808 (nMOF-808) exhibits enhanced reactivity than larger MOF-808 crystals, attributed to the higher coordination of hydroxyl and water molecules to the secondary building units (SBU) as determined using a range of X-ray absorption spectroscopy (XAS) techniques. These studies indicate that the crystal size-dependency in GPh degradation is related to structural modifications on coordinative unsaturated Zr site that promote the fast exchange of weakly bonded ligands. Taken together, this study demonstrates that GPh degradation can be optimized through ligand field tuning in MOFs, which can help improve overall reactivity while also pushing the reaction toward desirable, nontoxic products.}, archive = {J_ANGEW}, author = {Jhair A.

Unlike conventional electrolyte additives that favor (002) deposition, SPS enables dense (100) growth through a unique symmetrically aligned concentration-controlled adsorption network, affording structural uniformity and compactness to the Zn deposit layer. The dual-action symmetrical SPS additive adsorbs onto the Zn surface via vicinal sulfur atoms, blocking electrolyte access to the Zn anode, enhancing the transportation kinetics of Zn 2+ , and simultaneously promoting desolvation by displacing water molecules from the solvation shell.

Herein, a polymer additive was copolymerized by 1-vinyl-3-ethylimidazolium trifluoromethanesulfonate (VEImOTf) and methacrylamide (MAAm) (PVEMA) to alleviate the above issues. The polymer chain of PVEMA endows amphipathic properties for Zn 2+ diffusion and solvation structure regulation, and the α-methyl of MAAm enhances the hydrophobic properties to avoid side reactions on Zn metal. In addition, the imidazole groups adsorb onto Zn metal with electrostatic shielding effect for further side reaction alleviation and mitigate shuttle effects by electrostatic interactions with polyiodides.

Retinoic acid-inducible gene I (RIG-I) is a cytoplasmic receptor of the innate immune system that triggers antiviral responses upon detection of viral RNA. RIG-I can be specifically activated by short double-stranded (ds) RNA with a blunt 5′ end bearing a triphosphate, mimicking nascent viral transcripts. Tumor cells are specifically sensitive to RIG-I-induced cell death. Here we developed a potent oligonucleotide ligand for spatiotemporally controlled activation of RIG-I by light exposure. Through structural considerations and functional studies we identified a combination of two nucleoside positions in a RIG-I oligonucleotide ligand for which the substitution of both respective 2′-hydroxy groups of the ribose by photolabile protecting groups (2′-photocages) resulted in a complete loss of RIG-I ligand activity, whereas photocaging the individual positions was not sufficient to turn off RIG-I. Light exposure fully restored RIG-I activation by the photocaged RIG-I ligand, enabling light-controlled RIG-I-mediated cell death of human cancer cells which had internalized the photocaged RIG-I ligand prior to light exposure. This novel photoactivatable RIG-I oligonucleotide ligand may be applicable for precise light-controlled induction of tumor cell death in superficial cancer such as melanoma.}, archive = {J_ANGEW}, author = {Sandra Anika Lewash and Vivien Rose McKenney and Christine Wuebben and Janos Ludwig and Racha Hosni and Dirk Radzey and Marieta I.

Nevertheless, this process suffers from inferior NO3RR kinetics and nitrite accumulation owing to the linear scaling relation limitations for SACs. To break these limitations, a single-atom Cu-bearing tungsten oxide catalyst (Cu 1 /WO 3 ) was developed, which mediated a unique dual-driven NO3RR process. Specifically, WO 3 dissociated water molecules and supplied the Cu 1 site with ample protons, whereas the Cu 1 site in an electron-deficient state converted NO 3 − to NH 3 efficiently. The Cu 1 /WO 3 delivered an impressive NH 3 production rate of 1274.4 mg N h −1 g Cu −1 , a NH 3 selectivity of 99.2%, and a faradaic efficiency of 93.7% at −0.60 V, surpassing most reported catalysts. Furthermore, an integrated continuous-flow system consisting of a NO3RR cell and a vacuum-driven membrane separator was developed for NH 3 synthesis from nitrate-contaminated water. Fed with the Yangtze River water containing ∼22.5 mg L −1 of NO 3 − -N, this system realized an NH 3 production rate of 325.9 mg N h −1 g Cu −1 and a collection efficiency of 98.3% at energy consumption of 17.11 kwh g N −1 .

In this work, we report the design and synthesis of simple and stable short peptides ( D-FFxFFs ) that could specifically trigger ER-phagy, which further induces pyroptosis and activates the immune response against tumor cells. D-FFxFFs locate preferentially in ER and readily self-assemble to form nanosized misfolded protein mimics, which lead to distinct upregulation of dedicated ER-phagy receptors with no obvious autophagy of other organelles. Significant unfolded protein response (UPR) is activated via IRE1-JNK and PERK-ATF4 pathways. Interestingly, the persistent ER-phagy triggers ER Ca 2+ release and a surge in mitochondrial Ca 2+ levels, resulting in GSDMD-mediated pyroptosis other than apoptosis.

Herein, a porous noble-metal-free framework ( Cu-TCA) was synthesized, which can highly effectively catalyze the multicomponent conversion of CO 2 by modulating reaction pathways.

Control experiments and NMR spectroscopy revealed that CO 2 and propargylamine in the pores preferentially reacted to form oxazolidinones, which further reacted with phosphine oxide outside the pores to produce phosphorylated 2-oxazolidinones. Therefore, the reaction pathways and sequence of the substrates were controlled by the confinement effect of the pores in Cu-TCA .

In this study, we introduce a selenium-doping strategy to unlock the potential of EHAE in host molecules. To demonstrate this approach, we developed a straightforward method for synthesizing structurally diverse pyridine-fused, selenium-containing heteroacenes via an intramolecular radical cyclization of 2-(arylselanyl)pyridin-3-amine derivatives. This method facilitates the rapid construction of a novel host molecule, DCz-BSeP, by incorporating two carbazole groups into the benzo[4,5]selenopheno[2,3- b ]pyridine (BSeP) core. Compared to its oxygen-based (DCz-BFP) and sulfur-based (DCz-BTP) counterparts, the introduction of selenium in DCz-BSeP significantly enhances spin-orbit coupling and accelerates the reverse intersystem crossing rate of thermally activated delayed fluorescence (TADF) emitters by threefold, while also improving bipolar transport properties. These enhancements make DCz-BSeP an ideal bipolar host for high-performance, wide-color-gamut TADF-OLEDs, with notably reduced efficiency roll-off.

  @article{ , abstract = {The high selectivity and permeability of aquaporin proteins in water transport inspired the design of artificial water channels (AWCs). The water transport efficiency of both AQPs and AWCs is influenced by charged groups at the pore entrance. Here, we explored the mechanism of charge effects in pillar[5]arene AWCs using molecular dynamics (MD) simulations. The simulations demonstrate that the positively charged AWCs ( Ch + ) exhibit higher water permeability compared to the negatively charged AWCs ( Ch − ). The higher permeability of Ch + channels stems from the shorter hydrogen bond lifetimes between water molecules at the entrance region. In line with this, the rotational dynamics of water is faster in the entrance region of Ch + . Further analyses revealed two factors contributing to the distinct water dynamics in Ch + and Ch − channels: the direct interactions of the NH 3 + /COO − groups with water and the counter ions (Cl − /K + ) around these charged groups. NH 3 + groups in Ch + channels exert less stable H-bond interaction with water than the COO − group in Ch − channels. K + ions concentrated around the COO − groups retard the water rotation more effectively than the Cl − ions around the NH 3 + groups.

In this study, we demonstrate that anodic borohydride oxidation has great potential to successfully replace the use of such sacrificial anodes for a variety of electroreductive organic transformations.

  @article{ , abstract = {Long wave infrared (LWIR) birefringent crystals are essential for infrared optical applications but such materials are rarely reported due to the requirements of large birefringence and wide infrared transmission range. This study proposes a facile route to create new LWIR birefringent crystal by oxygenation strategy in halides with cations containing lone pair electrons. Given the tendency of such cations to form holodirected geometry, a divalent oxygen was introduced to substitute the monovalent halogen to decrease the coordination number and activate the lone pair electrons.

The holodirected SbCl 6 in Rb 13 Sb 8 Cl 37 has been successfully translated to hemidirected SbOCl 4 in Rb 3 Sb 2 OCl 7 and Rb 2 Sb 2 OCl 6 , which are the first examples in alkali metal antimony(III) oxyhalides. The birefringence of Rb 2 Sb 2 OCl 6 reached to 0.191@550 nm, which is 11.2 times that of Rb 13 Sb 8 Cl 37 (0.017@550 nm).

  @article{ , abstract = {Carbonyl dehydrogenation is one of the most valuable transformations in modern synthetic chemistry. As compared to traditional chemical synthesis methods, enzymatic dehydrogenation offers a greener and more selective alternative. However, except for a few rare natural dehydrogenases for desaturation, current enzymatic methods predominantly rely on enzyme promiscuity, which often suffers from lower efficiency and limited reaction controllability. Herein, we employed sequence similarity networks to mine natural dehydrogenases from a vast array of sequences with potential dehydrogenation activity. This approach led to the discovery of an uncharacterized FAD-dependent enzyme capable of efficiently performing the desymmetrizing desaturation of cyclohexanones, thereby generating diverse cyclohexenones bearing remote γ-quaternary stereocenters. The current method has enhanced the turnover frequency (TOF) by approximately 178-fold as compared to the best existing biocatalytic strategies and displayed almost no overoxidation reactions. Through a combination of experimental assays and computational studies, we elucidated that this enzyme enhances its dehydrogenation capability through an unconventional proton relay system, absent in previously reported enzyme promiscuity systems. Additionally, this streamlined enzymatic process demonstrated scalability to gram-scale synthesis with maintained efficiency and selectivity, offering robust and sustainable alternatives for the synthesis of chiral cyclohexenones with high optical purity.}, archive = {J_ANGEW}, author = {Yujing Hu and Jie Chen and Shaofang Qi and Hui Wang and Zhaoxuan Zhu and Yongzhen Peng and Wenjing Wang and Guixiang Huang and Zheng Fang and Yuxuan Ye and Zhiguo Wang and Kai Guo}, doi = {10.1002/anie.202501425}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {20}, pages = {e202501425}, shortjournal = {Angew.

A series of Ru-based c -SACs (Ru d =6.2 Å , Ru d =7.0 Å , and Ru d =9.3 Å ) are synthesized with predetermined SAD values, which are comprehensively characterized by various techniques.

L-Alanine benzyl ester hydrochloride (L-ABEHCl) containing carbonyl functionalized ammonium cation is incorporated into perovskite precursor solution, increasing the nucleation rate and reducing the crystal growth rate because of its strong interaction with precursor components, leading to increased grain size and crystallinity.

Herein, we report the facile “grafting-from” preparation of a nanourchin-like uricase-poly( L -proline) conjugate, namely UOx-PLP, with high grafting-density, enhanced thermal, lyophilization, freeze-thaw, and proteolytic stability. Through a transient preblocking strategy in the synthesis, the UOx-PLP overcomes activity loss and retains ~82 % enzyme activity. In Sprague-Dawley rats, UOx-PLP stimulates minimum complement activation and anti-UOx antibodies. Unlike PEG-UOx gave a significantly reduced half-life after repetitive administrations, UOx-PLP shows no sign of ABC effect. Moreover, the half-life of UOx-PLP remain almost unchanged when cross-administrated to rats previously received PEG-UOx and with high titers of anti-UOx antibodies. Finally, UOx-PLP shows minimum loss of efficacy after five straight administrations in a UOx knock-out hyperuricemia mice model, whereas PEG-UOx experiences sharp loss of efficacy upon the same treatment. Overall, the simple preparation and outstanding nonclinical results highlight the enormous potential of UOx-PLP for future clinical translation.}, archive = {J_ANGEW}, author = {Ruichi Zhao and Yangming Zhang and Banlai Ruan and Hairuo Zhang and Niannian Lv and Jiayi Li and Yuhe R.

Through in vitro triT acetylation and bioactivity assays, we show that acetylation functions as a resistance mechanism. Genomic searches of triculamin BGC genes across bacteria show that triculamin is more widely distributed than previously anticipated, as triculamin-like core peptides are found in at least three phyla in contrast to previously described lasso peptides that are typically restricted to one phylum. Triculamin BGCs with both canonical and non-canonical RiPP biosynthetic genes were identified. Two strains containing canonical triculamin-like BGCs were chemically characterized and shown to produce the novel triculamin-like lasso peptides palmamin and gelatinamin, the latter of which appears to have an unprecedented additional ring formation.

  @article{ , abstract = {Challenges like hydrogen evolution reaction (HER) and dendrite formation on zinc anodes hinder the practical application of aqueous zinc batteries (AZBs), primarily due to the lack of an exceptional passivating solid-electrolyte interphase (SEI). To effectively prevent water decomposition, it is essential to in situ construct SEI prior to water reduction. This study shifts the focus from aprotic to protic SEI chemistry and predicts reduction potentials of mild protic compounds using thermodynamics. Based on this insight, mild protic 2-mercapto-1-methylimidazole (MMI) is introduced and found to be reduced prior to water at higher electrode potentials, as MMI exhibits slightly higher proton activity than water due to its thiol group. The reduction of MMI produces isothiocyanate species via a proposed electrocatalytic ring cleavage mechanism, which deposit on zinc anodes to form an SEI predominantly composed of organic compounds supplemented with Zn(OH) 2 . Benefiting from the unique advantage of preferential reduction before water, the MMI-derived SEI exhibits a superior passivating effect, as evidenced by a two-order-of-magnitude reduction in corrosion current of zinc anodes from 1170 μA cm −2 to 13.6 μA cm −2 .

  @article{ , abstract = {Solid polymer electrolytes (SPEs) are widely recognized as promising candidates for enabling solid-state lithium metal batteries (SSLMBs) with improved safety, high energy density, and extended cycling life. The traditional perspective posits that increasing the mechanical modulus of SPEs enhances their capacity to regulate Li 0 deposition and suppress dendrite penetration. However, this study reveals a distinct failure mechanism: a rigid SPE with a high storage modulus suffers from delamination-induced cell failure due to its inability to accommodate the volumetric changes of the Li 0 anode. To address these limitations, we developed a hierarchical SPE incorporating an adhesive adaptation layer (AAL) positioned between the Li 0 anode and the rigid SPE. The AAL combines strong adhesive strength, effectively mitigating delamination, with flowability, allowing it to eliminate interfacial voids and defects. Structural characterization via Cryo-TEM and SEM demonstrates that this hierarchical design facilitates uniform, dense, and whisker-free Li 0 deposition, in sharp contrast to the uneven and porous morphology observed with the rigid SPE alone. Furthermore, the enhanced interfacial stability promotes the formation of an inorganic-enriched SEI layer, contributing to long-term cycling stability.

  @article{ , abstract = {Carbon, nitrogen, and hydrogen are among the most abundant elements in the solar system, and our understanding of their interactions is fundamental to prebiotic chemistry. CH 4 and N 2 are the simplest archetypical molecules formed by these elements and are both markedly stable under extremes of pressure. Through a series of diamond anvil cell experiments supported by density functional theory calculations, we observe diverse compound formation and reactivity in the CH 4 -N 2 binary system at high pressure. Above 7 GPa two concentration-dependent molecular compounds emerge, (CH 4 ) 5 N 2 and (CH 4 ) 7 (N 2 ) 8 , held together by weak van der Waals interactions. Strikingly, further compression at room temperature irreversibly breaks the N 2 triple bond, inducing the dissociation of CH 4 above 140 GPa, with the near-quenched samples revealing distinct spectroscopic signatures of strong covalently bonded C−N−H networks. High temperatures vastly reduce the required pressure to promote the reactivity between CH 4 and N 2 , with NH 3 forming together with longer-chain hydrocarbons at 14 GPa and 670 K, further decomposing into powdered diamond when temperatures exceed 1200 K.

  @article{ , abstract = {Acetaldehyde (CH 3 CHO) is of great industrial importance and serves as a key intermediate in various organic transformations. Photocatalytic production of acetaldehyde from CO 2 represents a sustainable route compared to conventional oxidation processes. However, current photocatalytic systems often face challenges, including limited product selectivity and dependence on sacrificial reagents. Here, we present a Cd 0.6 Zn 0.4 S (CZS) photocatalyst co-modified with sulfur vacancies and atomically dispersed Cu (Cu/CZS−Vs) for the efficient conversion of CO 2 to acetaldehyde. Charge density analysis reveals that sulfur vacancies induce charge accumulation around the adjacent metal atoms, creating active sites that strongly anchor CO 2 and H + , thereby promoting CO 2 conversion while suppressing the competing hydrogen evolution reaction. The atomically dispersed Cu sites facilitate the conversion of key intermediates (i.e., *CHO and *CO) to the crucial C 2 intermediate *OCCHO, which can subsequently be converted to acetaldehyde. As a result, this catalyst achieves an acetaldehyde yield of 121.5 μmol g −1 h −1 with a selectivity of ca. 80 % via photocatalytic CO 2 conversion in the absence of sacrificial agents, along with a quantum efficiency of ca. 0.53 % at 400 nm, underscoring its potential for practical CO 2 conversion applications.

Herein, we develop an atomically isolated Pt on RuO 2 (Pt 1 /RuO 2 ) catalyst composed of high-density Pt−Ru interfaces that ensure single-site adsorption of EG, enrich surface *OH coverage and weaken *CO−CH 2 OH intermediate adsorption, thereby synergistically promoting GA generation.

  @article{ , abstract = {Non-ribosomal peptide synthetases (NRPSs) are key enzymes in pharmaceutical synthesis, with condensation (C) domains catalyzing amide bond formation between aminoacyl substrates. However, recent research has elucidated that the catalytic capabilities of C domains extend beyond the traditional formation of peptide bonds. In this study, we elucidate the cyclization mechanism of the NRPS-derived natural products hangtaimycin (HTM), characterized by the formation of a 2,5-diketopiperazine (DKP) moiety which involves an intramolecular vinylamide-mediated nucleophilic attack instead of an N-terminal amino group. This cyclization is catalyzed by a terminal condensation-like (C T ) domain within the NRPS enzyme HtmB2. We investigated the evolutionary specificity of the HtmB2-C T within Streptomyces spectabilis CCTCC M2017417. Employing a multidisciplinary analytical approach, we have delineated the molecular underpinnings of DKP formation within the HTM biosynthesis. This process is facilitated by residue R2776, which modulates the formation of reactive species and stabilizes the amidate through electrostatic interactions. Besides, we found a positive correlation between the alkaline strength of the residue at position 2776 and the activity of HtmB2-C T .

The use of charged peptides instead of canonical phospholipid head groups offers advantages with respect to ease of acylation and chemical diversity. Here we demonstrate that native chemical ligation (NCL) enables in situ synthesis of diacylated lipopeptides (D-ALPs), which spontaneously self-assemble into micron-sized vesicles resembling cellular membranes. Diacylation occurs between non-amphiphilic peptides possessing an N -terminal cysteine, and acyl thioesters. Peptide head groups endow unique membrane functions, which is demonstrated by incorporation of an arginine-glycine-aspartic acid (RGD) motif, resulting in vesicle targeting to α v β 3 integrin-overexpressing cancer cells.

Tin halide perovskites (THPs) have garnered significant attention for IPVs due to their excellent optoelectronic properties without the environmental risks of lead exposure. However, THPs face challenges in controlling their fast crystallization process. Here, we introduce a novel approach to precisely control the crystallization kinetics of FASnI 2 Br perovskite via the formation of the 6H-intermediate phase, supported by the mesomeric (+M) interaction effect of 4-aminopyridine hydrochloride (4APCl) in the perovskite precursor. The grazing-incidence wide-angle X-ray scattering measurements indicated the formation of 6H-intermediate phase for the FASnI 2 Br-4APCl perovskite during the crystallization process. The in situ ultraviolet-visible absorption spectroscopy during the spin coating and annealing process confirmed the reduction of crystal growth rate after the 6H-intermediate phase formation. Thus, high-quality perovskite films were obtained with reduced defects. The resulting IPVs achieved an efficiency of 21.55 % under indoor illumination at 1000 lux, exceeding all types of lead-free perovskite IPVs.}, archive = {J_ANGEW}, author = {Muhammad Abdel-Shakour and Junfang Wang and Junjie Huang and Zhen Gao and Yongle Pan and Xiangyue Meng}, doi = {10.1002/anie.202421547}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {20}, pages = {e202421547}, shortjournal = {Angew.

  @article{ , abstract = {The development of synthetic methods capable of converting elemental sulfur into conjugated porous sulfur-rich polymers remains a great challenge, although direct utilization of this readily available feedstock can significantly enrich its uses and circumvent environmental problems during sulfur storage. We report herein mechanochemical (MC) nucleophilic aromatic substitution (S N Ar) that enables sulfur conversion into thianthrene-bridged porous ladder polymer networks with dense donor-acceptor (D−A) molecular junctions. We demonstrate that the key lies in the generation of bent thianthrene units through a solid-state ball-milling condensation reaction between 1,2-dihaloarenes and elemental sulfur. We also show that the assembling of D−A structural motifs into porous networks affords efficient visible-light-driven photocatalytic reduction of carbon dioxide (CO 2 ) with water (H 2 O) vapor, in the absence of any additional photosensitizer, sacrificial agents or cocatalysts. Exceptional photoinduced charge separation along with boosted exciton dissociation results in a high-performance of carbon monoxide (CO) production rate of 306.1 μmol g −1 h −1 with near 100 % CO selectivity, which is accompanied by H 2 O oxidation to O 2 , as confirmed by both experimental and theoretical results.

  @article{ , abstract = {Calcium sulfate, and especially its hemihydrate form (bassanite), is crucial in the construction industry, primarily used as a hydraulic binder in cements, mortars, and wallboards. Because of the rapid transformation of bassanite into thermodynamically stable gypsum (calcium sulfate dihydrate) upon contact with water, natural deposits are scarce, rendering it one of the most extensively produced inorganic materials worldwide. Currently, bassanite is derived from mined or waste gypsum through a thermal dehydration process, which is energy-intensive and costly. As sustainability has become a key target for industrial processes and products, a series of studies aiming to increase the energy efficiency and reduce the carbon footprint of bassanite production was published recently. Two primary approaches are pursued: conversion of gypsum and direct precipitation of bassanite from solution. In both cases, organic solvents, (specific) additives and/or elevated temperatures have been used to control the activity/availability of water in the reaction medium and thus direct phase selection towards bassanite.

  @article{ , abstract = {Linking-site engineering, used to graft two or more monomers, is crucial for achieving high-performance Y-series giant molecule acceptors (Y-GMAs). However, the reported Y-GMAs all use a single-typed linking site, making it difficult to finely-tune their optoelectronic properties. Herein, we develop a non-fully conjugated Y-GMA (named 2Y-we), with hybrid linking sites at the wing and end-group of monomers, to combine the respective advantages of the wing and end-group site linked counterparts. Compared to its parental monomer, 2Y-we shows different intermolecular interactions, crystallinity, packing, and glass transition temperature, allowing optimized active layer morphology (including appropriate phase separation and ordered molecular packing) and stability. Consequently, the D18/2Y-we-based organic solar cells (OSCs) obtain an improved power-conversion-efficiency (PCE) of 17.4% with both higher open-circuit voltage ( V OC ) and short-circuit current density ( J SC ), due to the reduced energy loss and efficient exciton dissociation. Inspired by its high V OC × J SC , 2Y-we is introduced into D18:L8-BO to fabricate ternary devices. Thanks to the further optimized morphology and improved charge transport, the ternary OSCs achieve a superior PCE of 19.9%, which is the highest value among the reported nonfully conjugated Y-GMAs.

The inclusion of an aldehyde group in the synthesis enhances polymerization reactivity, reduces the amount of superacid required, and ensures that the piperidinium is suspended from the ether-free polymer backbone. The accelerated aging analysis demonstrates that the pendant structure of piperidinium effectively suppresses the Hofmann elimination, resulting in PAMP AEM with exceptional alkali stability, surpassing that of the commercial PiperION-A40.

  @article{ , abstract = {Hydrogen vacancies (V H ) were considered major non-radiative recombination centers in hybrid perovskites. By employing a multiscale approach that combines first-principles calculations and molecular dynamics (MDs) simulations, our findings indicated that the V H impact was overestimated due to the previous metastable V H configurations. The organic molecules with V H located on either the nitrogen or carbon atom act as the ligands that form energetically stable dimers with Pb 2+ cations. These dimers lower V H energy by 0.35–0.97 eV in MAPbI 3 and by 0.88–1.01 eV in FAPbI 3 , compared to non-bonding configurations. These dimers significantly boosted potential energy barriers of hole capture, resulting in a dramatic reduction in carrier capture coefficients by over 10 orders of magnitude. Consequently, the total capture coefficients ( C total ) for the dominant V H in MAPbI 3 and FAPbI 3 are on the order of 10 −17 and 10 −31 cm −3 s −1 , respectively.

  @article{ , abstract = {Both reducing singlet-triplet energy gaps (Δ E S1T1 ) and enhancing spin-orbit couplings (SOCs) are key to improving reverse intersystem crossing rates ( k RISC ) in thermally activated delayed fluorescence (TADF) materials. While considerable efforts have focused on reducing Δ E S1T1 , investigations on SOCs remain limited. Here, blocking π-conjugation in carbonyl-embedded polycyclic heteroaromatic (PHA) molecules as potential approach to elevate ππ* excitation energy, allowing its hybridization with nπ* excitation, thereby increasing SOCs is proposed. Two proof-of-concept isomers, DNDK-1 and DNDK-2 are synthesized, with different orientations of carbonyl units. DNDK-1 adopts a heavily twisted structure that hinders π-conjugation, while DNDK-2 remains quasi-planar, maintaining stronger π-conjugation. Experimental measurements reveals stark differences in their photophysical properties, with DNDK-1 exhibiting faster k RISC and much higher electroluminescence efficiency. The ab-initio calculations elucidate that hindered conjugation in DNDK-1 elevates ππ* excitation energy, enabling nπ*-ππ* mixing, thus significantly boosting SOCs. In contrast, smooth π-conjugation in DNDK-2 leads to marginal nπ*-ππ* mixing. In addition, utilizing groups composed of meta-arranged carbonyl-Ar-carbonyl and meta-arranged N-Ar-N units emerges as another approach to block π-conjugation and enhance SOCs.

Detailed structure characterizations demonstrate the controllable construction of Pd single-atom and Pd ensemble sites modified Cu surfaces and PdCu alloy via fine tuning the Pd/Cu ratios. Catalytic tests, kinetics analysis, and temperature-programmed experiments demonstrate that the presence of Pd ensemble sites on Cu surface directly catalyzes the hydrogenation of propyne that occurs on the Cu sites in other cases, and enables a facile activation for hydrogen and simultaneously promotes the desorption of propylene against its hydrogenation. Accordingly, the selectivity to target propylene is up to 95.3% at the full conversion of propyne on the corresponding Pd 0.1 Cu catalyst.

To address the challenge, we propose an alkali-ion-H 2 O-poor coordination strategy to effectively regulate water migration by incorporating low molecular polarity index (MPI) anions. In situ Raman, synchrotron spectroscopy, and molecule dynamic simulations reveal that the repulsion of low MPI anions to water effectively disrupts the hydration patterns around the alkali cations, and thereby minimizes the concomitant water migration.

The findings emphasize the crucial role of solvent effects in modulating catalytic performance, with a 75% CH 3 CN solution offering the most efficient recovery. The solvent not only influenced the oxidation and coordination steps crucial for Au extraction but also facilitated electron and mass transfer, accelerating the generation of reactive species that promote Au dissolution. Furthermore, water amplified the effect of the solvent by modifying the chemical potential of surface species, thus optimizing catalytic reactivity. Under ultrasonic vibration, the piezocatalytic system achieved 100% Au recovery from various types of E-waste, exhibiting excellent adaptability across a broad pH range.

  @article{ , abstract = {Polyethylene (PE) is the most widely produced plastic but accumulation and resistance to degradation has significantly contributed to the plastic waste crisis. Upcycling has presented promising solutions to transform PE waste into value-added products. In this study, mixed post-consumer PE was successfully repurposed into reprocessable and chemically recyclable cross-linked polyethylene (XLPE). This process involved converting PE into telechelic oligomers, followed by repolymerization using a hybrid cross-linking system consisting of a dynamic cross-linker 2,4,6-triethoxy-1,3,5-triazine (TETA) and non-dynamic cross-linker tris(6-isocyanatohexyl)isocyanurate (Tri-HDI). In the resulting XLPE, TETA facilitated iterative reprocessing with minimal property degradation across cycles, whereas Tri-HDI helped preserve functional performance throughout service life. Compared to PE, XLPE exhibited enhanced mechanical properties, reduced creep deformation under application-relevant temperatures, and high temperature structural stability. Notably, copolymerizing PE oligomers with commercial macrodiols was employed to create composite XLPEs, enabling tuning material properties. After use, XLPE can be efficiently and selectively depolymerized under mild conditions, even when mixed with commercial insulator cables. This depolymerization allows for the recovery of the constituent building blocks, enabling purification and subsequent repolymerization for reuse.

  @article{ , abstract = {Aliphatic polyesters synthesized via ring-opening polymerization (ROP) have properties competitive to incumbent plastic (PE, PP), while simultaneously opening up for chemical recycling to monomer (CRM). However, not all aliphatic polyesters are prone to undergo CRM, and the ability to shift the equilibrium between polymer and monomer is tightly associated with the initial monomer structure. The standard strategy to measure CRM is to evaluate the change in free energy during polymerization (∆G ROP ). However, ∆G ROP is only one-dimensional by assessing the equilibrium between initial monomer and polymer. But under active catalytic conditions, the depolymerization of polymers can lead to formation of larger rings, such as dimers, trimers, tetramers, and so on, via the ring-chain equilibrium (RCE), meaning that the real thermodynamic recycling landscape is multi-dimensional. This work introduces a multi-dimensional chemical recycling to all rings (CRR) via a highly active catalytic system to reach RCE. Thermodynamically ∆G RCE is completely different from ∆G ROP . Using ∆G RCE instead of ∆G ROP allows us to achieve CRR for polymers notoriously difficult to achieve CRM for, as exemplified within by CRR for poly(ε-caprolactone), poly(pentadecalactone), and mixed polymer systems.

  @article{ , abstract = {The operational perovskite/organic tandems are subjected to light irradiation and driven by a higher bias voltage than single-junction solar cells, posing a severe challenge to their stabilities. Light irradiation can trigger halide phase segregation in the perovskite subcell, exacerbated under higher bias voltage through electron–phonon coupling. To address this, dimethylammonium ion (DMA + ) incorporation delays perovskite crystallization by forming an intermediate phase, enhancing crystallinity, and reducing lattice structural defects. DMA + with a larger ionic radius entering the A-site of lattice tilts the [PbX 6 ] 4− (X: I or Br) octahedral, enlarging the perovskite bandgap, shortening Pb─I bonds, and reinforcing the lattice. This mitigates halide escaping from the lattice and subsequent ion migration. Phase segregation in the perovskite subcell is significantly suppressed under high-power irradiation and bias voltage. Consequently, the perovskite subcell exhibits increased and stable quasi-Fermi-level splitting values, delivering a high open-circuit voltage of 1.34 V.

  @article{ , abstract = {The practical application of sulfur (S) cathodes in lithium-sulfur (Li-S) batteries is hindered by the shuttling of soluble lithium polysulfides (LiPSs) and sluggish sulfur redox kinetics. Addressing these challenges requires advanced catalytic host materials capable of trapping LiPSs and accelerating Li-S redox reactions. However, single-site catalysts struggle to effectively mediate the complex multi-step and multi-phase sulfur conversion processes. In this study, we present a novel dual-site catalyst, Ni-MoC-NC, featuring nickel single atoms anchored to nitrogen sites (Ni-N 4 ) within a carbon nitride (NC) matrix and molybdenum carbide (MoC) nanoclusters. Experimental and theoretical analyses reveal that MoC sites efficiently catalyze the reduction of long-chain LiPSs (Li₂S₈ to Li₂S₄), while Ni-N 4 sites drive the reduction of short-chain LiPSs (Li₂S₄ to Li₂S), resulting in a synergistic enhancement of the complete Li-S redox process. When incorporated as a coating on the cathode side of a commercial polypropylene (PP) separator, the Ni-MoC-NC catalyst enhances sulfur utilization, suppresses LiPSs shuttling, and facilitates a uniform Li + -ion distribution, effectively mitigating the uncontrolled growth of lithium dendrites. Thereby, Li-S batteries employing an S/Ni-MoC-NC cathode and a Ni-MoC-NC@PP separator demonstrate outstanding performance, including an initial capacity of 1624 mAh g⁻¹ at 0.2C and 1142 mAh g⁻¹ at 1C, retaining 590 mAh g⁻¹ after 800 cycles.

Specifically, in contrast to the O─O dimers formed within typical anionic-redox active cathodes, the oxidation of lattice oxygen in LFO generates O − stabilized in Li 6 -O configuration. Significantly, a pair of edge-sharing Li 6 -O configurations transforms into a superoxo dimer, which further evolves into O 2 via a ligand-to-metal charge transfer process.

The l -Pt@Au octapods showed a nearly twofold stronger SERS response to Aβ40 and Aβ42 monomers and fibrils than the d -Pt@Au octapods. The different association constants arose from the unique chiral recognition capabilities of the CT ligands on the surfaces of the l -Pt@Au octapods, which allowed them to form specific hydrogen bonds with Aβ40 and Aβ42 monomers and fibrils, producing significant differences in their Raman spectra.

  @article{ , abstract = {Targeted membrane protein degradation using cell surface E3 ligases RNF43/ZNRF3 via proteolysis targeting chimeras (PROTACs) represents an effective strategy for treating membrane drug targets that cannot be fully inhibited using traditional inhibitors. Several ingenious chimeras have been developed to tether RNF43/ZNRF3 to target membrane proteins, resulting in the degradation of targets at sub-nanomolar concentrations both in vitro and in vivo. However, currently available RNF43/ZNRF3 binders are genetically encoded and have poor plasticity, which limits the design and promotion of such PROTACs. Here, we exploited the AlphaFold-predicted complex structures of ligand-bound RNF43/ZNRF3 and developed a class of chemically tailored peptide binders for ZNRF3/RNF43. With these peptide binders that can be conveniently prepared by de novo peptide synthesis, we established a new membrane protein degradation platform that allows versatile modular design and targeted degradation of clinically relevant membrane proteins, i.e., PD-L1 and EGFR.

  @article{ , abstract = {Argyrodite-based sulfide electrolytes have received considerable attention in all-solid-state lithium metal batteries owing to their high ionic conductivity and good mechanical property. However, the reactivity between sulfide electrolytes and lithium anode leads to continuous interfacial reactions and dendrites growth, which severely hinders their practical applications. We propose an electron localization strategy by modulating the d–p orbital hybridization within the PS 4 tetrahedral structure of Li 6 PS 5 Cl through homogeneous incorporation of yttrium (Y) and oxygen (O). The introduction of Y strengthens the Madelung energy with sulfur (S) atom and induces the electronic localization of S atom, which suppresses the interaction between lithium metal and S atom of the tetrahedron. The air-stability is also enhanced due to oxygen introduction. Furthermore, the in situ formation of Li 2 O interphase acts as a protective barrier, synergistically mitigating the interfacial reactions between lithium metal and Li 6 PS 5 Cl. The Li symmetric cell with the modulated Li 6 PS 5 Cl electrolyte achieves stable lithium plating/stripping for over 4800 h.

  @article{ , abstract = {Molecular catalysts play a critical role in regulating the selectivity of electrocatalytic CO 2 reduction reaction (CO 2 RR), yet the understanding of ligand function is largely restricted to modulating the electronic structure of the metal and reaction kinetics. Herein, a hydroxyl (─OH) ligand is introduced into a sterically hindered amino-porphyrin (o-TAPP) to synthesize the atropisomers porphyrin-salicylimine-Cu (o-Cu-Por-Sa) with hydrogen-bonding interactions (O─H⋯O), enabling efficient selection of CO and CH 4 under dual effects. Detailed analysis shows that the ─OH of o-Cu-Por-Sa (αβαβ) forms a noncovalent hydrogen bond with carbonate, characterized by a bond length of 2.01 Å and an angle of 27.6°, and this interaction reduces the reaction energy barrier, achieving a faradaic efficiency (FE) of 84% for CH 4 . Moreover, the steric hindrance effect of the symmetric distribution of ─OH facilitates protonation reactions by preventing C–C coupling. In contrast, ─OH aggregated on o-Cu-Por-Sa (αααα) forms a pocket-like hydrogen bond grid, which restricts free CO 2 adsorption, and the rapid dissociation of *CO also interrupts the reaction.

Despite extensive research, a comprehensive understanding of the internal crowdedness within single polymer chains in dilute solutions remains challenging, and direct evidence to visualize and manifest this effect is scarce. Aggregation-induced emission (AIE) offers a novel method to address this challenge. To achieve this, a vinyl-derivatized AIE monomer was polymerized using atom transfer radical polymerization (ATRP) in a controlled way. Afterward, the end group of the synthesized polymer chain was transformed to azide, which was coupled with an alkyne-derivatized norbornene unit using click chemistry to produce the macromonomer. Ring-opening metathesis polymerization (ROMP) of the norbornenyl macromonomer using Grubbs catalyst, (H 2 IMes)(pyr) 2 (Cl) 2 Ru = CHPh (G3), resulted in well-defined bottlebrush polymers in a highly efficient way.

  @article{ , abstract = {Herein, we report a method that significantly enhances the atom economy of catalysts in living polymerization. By introducing intermittent, switchable chain-transfer reactions during the polymerization process, multiple regenerations of the catalyst are achieved while preserving the “living”/controlled characteristics. The specially designed catalytic system, composed of 1,2-dipyrrolidinoethane/n-butyllithium/n-butylpotassium/toluene, exhibits a chain-transfer rate that is highly sensitive to temperature. It enables living polymerization at low temperatures, while at high temperatures, rapid chain transfer to toluene occurs. Utilizing this characteristic, polymerization is initially carried out at low temperatures; once the monomer is consumed, increasing the temperature promotes chain transfer, resulting in initiator regeneration. The regenerated initiator can then initiate new cycles of living polymerization upon the addition of fresh monomers. This process was repeated for more than a dozen cycles, achieving an initiator efficiency of up to 1500%.

In this study, we introduce a recyclable nonmetallic polymer material (vitrimer) as a catalyst for a new platform in contact-electrocatalysis. This approach harnesses the contact charges generated between water droplets and vitrimer to drive CO 2 RR, achieving methanol selectivity exceeding 90%. The imine groups within the vitrimer play a dual role, facilitating CO 2 adsorption and enriching friction-generated electrons, thereby mediating efficient electron transfer between the imine groups and CO 2 to promote CO 2 RR. After 84 h of CO 2 RR, the system achieved a methanol production rate of 13 nmol·h −1 , demonstrating the excellent stability of the method. Moreover, the vitrimer retains its high-performance electrocatalytic activity even after recycling.

However, they are typically restricted to one imaging modality and have fixed properties such as size, shape, toxicity profile, or photophysical characteristics, which hampers a comprehensive view of biological processes. Herein, rationally designed dye assemblies are introduced as a unique CA platform for simultaneous multimodal and multiscale biomedical imaging. To this end, a series of amphiphilic aza-BODIPY dyes are synthesized with varying hydrophobic domains ( C 1 , C 8 , C 12, and C 16 ) that self-assemble in aqueous media into nanostructures of tunable size (50 nm–1 µm) and photophysical properties. While C 1 exhibits oblique-type exciton coupling and negligible emission, C 8 - C 16 bearing longer alkyl chains undergo J -type aggregation with NIR absorption and emission and excellent photoacoustic properties. Given these advantageous features, aza-BODIPY specific, semi-quantitative fluorescence reflectance and photoacoustic imaging both in vitro and in vivo are established. Additionally, in vitro cell viability as well as murine in vivo biodistribution analysis with ex vivo validation showed excellent biocompatibility and a size-dependent biodistribution of nanostructures to different organ beds.

The installation of cleavable bonds into the strands of thermosets using cleavable comonomers as additives can facilitate thermoset deconstruction without replacement of permanent cross-links, but such monomers can lead to reduced thermomechanical properties and require high loadings to function effectively, motivating the design of new and optimal cleavable additives. Here, we introduce “strand-fusing cross-linkers” (SFCs), which fuse two network strands via a four-way cleavable cross-link. SFCs enable deconstruction of model polydicyclopentadiene (pDCPD) thermosets with as little as one-fifth of the molar loading needed to achieve deconstruction using traditional cleavable comonomers. SFCs function under traditional oven curing as well as low-energy frontal ring-opening metathesis polymerization (FROMP) conditions and lead to improved thermomechanical properties, for example, glass transition temperatures, compared to prior cleavable comonomer designs.

To address this, we introduce potassium sulfocyanate (KSCN) as an electrolyte additive capable of delivering up to 100% active K ions. During initial charging, KSCN undergoes oxidative decomposition at 3.6 V, releasing active K ions and forming the cosolvent thiocyanogen ((SCN) 2 ). This molecule, meeting diverse electrochemical properties, was identified using unsupervised machine learning and cheminformatics. The approach demonstrated full KSCN conversion and excellent compatibility with all cell components. The presence of (SCN) 2 cosolvent enhanced the rate capability of anodes by promoting K-ion desolvation.

  @article{ , abstract = {Mechanically flexible crystals are a rapidly growing class of functional molecular materials. Typically, such flexible crystals are discovered by serendipity. Herein, we have predicted mechanical flexibility in a series of molecular crystals based on a structure screening approach that combines interaction topology and the presence of nitrile···nitrile interactions—a supramolecular motif hitherto not associated with bending property. Further, we have experimentally validated plastic/elastic bending properties in a series of crystal structures thus predicted. However, four out of five of these crystals showed the bending direction along π···π stacking despite the fact that the direction of strongest interaction anisotropy was rendered by the nitrile···nitrile interaction motifs. This is contrary to the commonly perceived anisotropy model and underscores the dominant role of dispersion forces over the electrostatically stabilized motifs in dictating the bending phenomena in molecular crystals. The interaction energies of these motifs have been evaluated using accurate structures from X-ray quantum crystallography. Analyses combining elastic tensors, interaction anisotropy indices, thermal expansion studies, and high-pressure simulations quantify the relative roles of the nitrile···nitrile motif and π···π stacking in mechanical flexibility.

However, controlling SMA morphology remains a significant challenge due to their strong aggregation tendency. Existing methods, including high-temperature annealing, and introducing high boiling point additives, frequently yield disordered polymorphs with limited scalability.

This marks the first demonstration of such an ordered SMA polymorph, exhibiting optical properties comparable to ideal crystals, including enhanced anisotropy, refractive index, and extinction coefficients. The specific polymorph further enables the formation of a well-organized PM6 donor arrangement, establishing an optimal bicontinuous network morphology.

First, the combination of computational modeling and experimental validation was performed to rapidly identify the most suitable redox partner (PetH/PetF). Next, the interactions between PetF and OleP were investigated and the engineering on PetF was conducted to enhance the efficiency of electron transfer. Using a novel microplate screening method, a superior mutant (PetF F64D ) was efficiently selected, which exhibited a significant enhancement in MDCA conversion yield from 32.5% to 80.9% and total turnover number (TTN) from 406.2 to 1617.9. Finally, through a combination of molecular dynamics simulations, the analysis of electron transfer pathway, and the calculations of electron transfer rate, the mechanism of electron transfer was investigated. The applied engineering strategies, high-throughput screening methods, and analytical approaches provide a feasible way to construct an ideal redox partner for other P450 enzymes.}, archive = {J_ANGEW}, author = {Chixiang Sun and Yongchao Wang and Baodong Hu and Jianan Wang and Jingwen Zhou and Jianghua Li and Jian Chen and Guocheng Du and Binju Wang and Xinrui Zhao}, doi = {10.1002/anie.202423209}, journal = {Angewandte Chemie International Edition}, month = {5}, number = {19}, pages = {e202423209}, shortjournal = {Angew.

The organocatalytic ring-opening polymerization was systematically studied using a range of common and readily available organocatalysts. Phosphazene base ( t -BuP 2 ) was identified as the most effective catalyst, offering excellent control over the entire polymerization. The regioselectivity of the synthesized polycarbonates, ranged from 0.74 to 0.99, with the highest value achieved when the side group was isopropyl (highest steric hindrance). Notably, the α -substituent in the monomers reduced the ring strains, allowing the resulting polycarbonates to be fully recycled to the monomers without decarboxylation. The recycling process effectively traps CO 2 in a closed loop between monomers and polymers, preventing its release into the atmosphere. The alkyl side groups enhanced the hydrophobicity of the polycarbonates, thereby reducing the likelihood of CO 2 release through hydrolysis during their lifecycle, achieving a robust CO 2 closed-loop fixation.

The designed electrochemical device features a gas cathode with a nanoscale Co catalyst and a metallic lithium anode. When CO 2 is introduced to the cathode, it undergoes a two-step lithium-related electrochemical reduction, converting it sequentially into Li 2 CO 3 and Li 2 O. Li 2 O is then oxidized to produce O 2 gas at the expense of renewable electrical energy. This process achieves an impressive O 2 yield exceeding 94.7%, significantly outperforming the efficiency of natural photosynthesis. Moreover, the O 2 yield can be further increased to 98.6% by employing an optimized RuCo catalyst.

  @article{ , abstract = {Understanding root–bacteria interactions with plant growth-promoting rhizobacteria (PGPR) is key to developing effective biofertilizers for sustainable agriculture. We performed single-cell force spectroscopy using the atomic force microscope (AFM) to study the primary attachment of two PGPR, Bacillus velezensis and Pseudomonas defensor , to different regions of Arabidopsis thaliana roots. Force measurements with individual cells uncovered distinct attachment strategies by each strain, involving binding via micrometer-long polymers from both bacteria and root surfaces. Flagella differentially affected the binding interactions of each PGPR; their removal altered binding characteristics differently for each strain, highlighting the importance of flagella in early root colonization. Using silica beads to mimic the negatively charged bacteria, we demonstrated the influence of electrostatic forces on root–bacteria interactions. We also examined interactions with abiotic surfaces of varying surface energies, revealing the roles of hydrophilic and hydrophobic forces in initial binding. Our measurements show that differences in the physicochemical properties of bacteria and roots are responsible for variations in primary attachment strategies between PGPR strains and root regions. Parallel fluorescence measurements corroborated our AFM single-cell analysis. Overall, our results provide a nanoscale view of bacterial attachment to roots, offering key insights into how beneficial bacteria colonize roots, crucial for enhancing biofertilizer effectiveness.}, archive = {J_ANGEW}, author = {Yilei Xue and Mackenzie Eli W.

  @article{ , abstract = {Photocatalytic oxidation of benzene to phenol using molecular oxygen (O 2 ) is a promising alternative to the traditional cumene process. However, the selectivity toward phenol is often poor due to the ring-opening reaction induced by the superoxide radical (⋅O 2 − ), which is predominantly produced from the single-electron reduction of O 2 . Herein, we demonstrate that introducing abundant oxygen vacancies (OVs) on the surface of titanium dioxide (TiO 2 ) facilitates the activation of O 2 through a two-electron reduction process instead of a single-electron reduction. This effectively suppresses the generation of ⋅O 2 − , thereby reducing phenol decomposition and significantly enhancing the selectivity. In addition, these OVs can trap the electrons to promote chare separation and serve as the adsorption sites for O 2 activation. As a result, the introduction of abundant OVs on the surface of TiO 2 not only enhances phenol yield but also importantly improves selectivity toward phenol. This finding enriches our understanding of how OVs influence reaction pathways and product selectivity, providing valuable insights for the design and tailoring of OV-rich photocatalysts for selective organic oxygenations.}, archive = {J_ANGEW}, author = {Shengyang Zhong and Dexi Yu and Yuhui Ma and Yuhong Lin and Xiaoyi Wang and Zhenzhen Yu and Meirong Huang and Yidong Hou and Masakazu Anpo and Jimmy C.

AMO responded to H 2 O 2 and glutathione (GSH) stimuli, releasing Ag + and MoO 4 2− ions, generating reactive oxygen species (ROS), and depleting GSH, thereby inducing ferroptosis and pyroptosis. The MoO 4 2− also inhibited cell migration and upregulated GSDME expression, converting apoptosis into caspase-3/GSDME-mediated pyroptosis. Additionally, DNA damage and ROS activated the cGAS-STING pathway, enhancing innate immunity. In vivo experiments demonstrated that the combination of AMO and the immune checkpoint inhibitor αPD-1 significantly inhibited tumor growth. This combination promoted dendritic cells (DCs) maturation, increased effector T cell numbers, induced M1 macrophage polarization, and alleviated immunosuppression. This study contributed to a deeper understanding of metal oxoanion-mediated pyroptosis, supporting its potential application in cancer immunotherapy.}, archive = {J_ANGEW}, author = {Hao Chen and Binbin Ding and Jia Tan and Qi Meng and Jing Li and Wenying Zhang and Pan Zheng and Bin Liu and Ping'an Ma and Jun Lin}, doi = {10.1002/anie.202501530}, journal = {Angewandte Chemie International Edition}, month = {4}, number = {18}, pages = {e202501530}, shortjournal = {Angew.

The synergistic halogen interactions between DFBB and the active layer matrix balances the differences in crystallinity between the donor and acceptor during the film formation process, promotes the formation of dense molecular packing and ordered orientation, optimizes the vertical composition distribution, and promotes the formation of domain sizes close to the exciton diffusion distance.

  @article{ , abstract = {The development of photoinitiators (PIs) combining high initiation ability, low-toxicity, and availability for high-precision 3D printing is a key challenge and an urgent problem to be solved nowadays in photopolymerization. In this study, carbazole chalcone glyoxylate oxime ester derivatives (denoted as Cs, C1−C5) containing both glyoxylate and oxime ester moieties with good light absorption properties in the visible range have been designed as type I PIs for the free radical photopolymerization (FRP) of trimethylolpropane triacrylate (TMPTA) and ethoxylated trimethylolpropane triacrylate (ETPTA) under 405 nm and 450 nm light-emitting diodes (LEDs) as well as sunlight irradiation. The reaction properties and mechanism of Cs are firstly predicted by molecular modeling/molecular design, which anticipate that C5 could exhibit the best photoinitiation ability, this structure being more prone to decarboxylation. Subsequent experimental results clearly show that the photoinitiation ability of C5 outperforms that of the benchmark commercial PIs (methyl benzoylformate (MBF), diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide (TPO)), and phenylbis (2,4,6-trimethylbenzoyl)-phosphine oxide (BAPO) under the same conditions.

The photochemical mechanism of C5 is systematically and comprehensively analyzed using a combination of steady state photolysis, decarboxylation reaction, fluorescence experiments, and electron spin resonance-spin trapping (ESR-ST) technology. It is found that both glyoxylate and oxime ester in C5 are highly active and capable of undergoing decarboxylation reactions to produce CO 2 and free radicals, which is consistent with the results predicted by molecular modeling. Furthermore, the low-toxicity of C5 is evidenced by cytotoxicity assays.

  @article{ , abstract = {Electron transport properties of cathode interlayers are crucial to high-performance organic solar cells (OSCs). We propose a novel approach to enhance electron transport of cathode interlayers through controlling a preferential face-on molecular orientation of non-ionic perylene-diimide- (PDI) based cathode interlayers with restricted n-doping effects. 1-(2,5,8-trioxadec-10-yl)-1,2,3-triazole (TOT) units as bulky and extended side chains were incorporated into brominated-PDIs via click chemistry to yield PDIBr-TOT. TOT side chains impart PDI-based interlayers with a dominant face-on orientation, meanwhile leading to a negligible doping effect due to their weak electron-donating properties. Impressively, at a slight doping level, higher electron mobility is gained through efficient vertical charge transport channels built by preferred face-on molecular orientations of PDIBr-TOT, beating the results acquired through strong doping effects of traditional PDIBr−N with an edge-on orientation. Thus, PDIBr-TOT can suppress exciton recombination and lower the surface energies for good contact with active layers, consequently leading to increases in fill factor and short-circuit current. Integrating PDIBr-TOT with various active layers, a remarkable efficiency of 19.52 % is obtained. Moreover, device stability is enhanced by restrained doping effects.

To address this gap, we have undertaken a mechanistic investigation, employing in situ X-ray absorption spectroscopy (XAS) coupled with electrochemical studies and density functional theory (DFT) calculations to further understand how Ni single atoms work in conjunction with the nitrogen-doped carbon matrix to promote CO 2 RR to CO, and how the presence of impurities such as those present in CO 2 -containing waste flue gases (including NO x , and CN − ) changes the catalyst upon reduction. In contrast to previous works, we do not find strong evidence for a purely metal-based reduction upon application of negative reductive potentials. Instead, we present evidence for an increase in the equatorial vs. axial splitting of Ni, consistent with electrons moving onto the reactants via the Ni single atom 3d z 2 orbital.

The developed methodology operates under mild conditions, does not require any additives or bases, features low catalyst loadings (1 mol %), fast reaction times (2–8 hours), and is compatible with a wide variety of functional groups, including halides, trifluoromethyl, alkenyl, alkynyl, and (hetero)aryl groups. Extensive mechanistic studies revealed that after base-free activation of the nitrile, either the N-bound manganese-ketenimine (propionitrile or benzyl cyanide) or the C-bound manganese-cyanoalkyl (acetonitrile) complex is formed. The difference in stability of these two species explains why more sterically hindered and presumably less activated nitriles ( i.e ., propionitrile, and butyronitrile) show higher reactivity than their corresponding more activated congeners ( i.e ., acetonitrile).

In this work, we returned to the classic perspectives of kinetics and thermodynamics, introducing a small amount of reduced glutathione (RGSH) to reshape the kinetic behavior of Zn 2+ deposition and increasing the thermodynamic energy barrier of HER. Specifically, the steric hindrance effect of RGSH tuned the electrochemical reduction kinetics to match Zn 2+ migration and increased the proportion of Zn 2+ in the bulk phase migration, thereby inducing dendrite-free deposition behavior with ordered (002) texturing. Meanwhile, RGSH with abundant hydrogen bond donors and acceptors reconfigures the coordination network of water molecules for all-climate adaptability, eliminating the accumulation of “dead Zn” at low temperature and the HER corrosion at high temperature. As a result, the advanced Zn||Zn symmetric cells deliver an extra-long cycling performance (over 4600 h) and a wide temperature tolerance (−20 °C~70 °C).

  @article{ , abstract = {The “oxo-wall” is a well-established concept in the area of bioinorganic chemistry, which refers to the instability of the terminal metal-oxo complexes in the +4 oxidation state, with tetragonal C 4v symmetry beyond group 8 elements. This leads to a diverse and highly reactive chemistry of Co-oxo complexes, as evidenced in the literature, ranging from challenging C−H bond activation to efficient water oxidation. Despite extensive research on first-row terminal metal-oxo complexes and the “oxo-wall” concept, studies correlating the reactivity of these species across the periodic table remain scarce. In this work, using a combination of DFT and ab initio CASSCF calculations, we have explored the structure, bonding, and reactivity of [M IV/V (15-TMC)(O)(CH 3 CN)] m+ (M= Mn, Fe and Co) species. Our study reveals several intriguing outcomes: (i) while existing literature typically indicates the presence of either Co IV =O or Co III –O • species beyond the wall, we propose a quantum mechanical mixture of these two species (termed as Co IV =O Co III –O • ), with the per cent of mixing dictated by ligand architecture and symmetry considerations; (ii) we observe that the oxyl radical character increases beyond the wall, correlating with larger N trans -M−O tilt angles; and (iii) we identify an inverse relationship between the percentage of M–O • character and the kinetic barriers for C−H bond activation.

In recent years, efforts in academia and industry have focused on modifying Pep2-8, a classical antagonistic peptide targeting proprotein convertase subtilisin/kexin type 9 (PCSK9), to enhance its specificity and affinity. However, developing effective PCSK9 inhibitory peptides remains challenging, especially given the limited examples of their successful in vivo applications. Here, we designed transformable inhibitory peptide (TIP) against PCSK9 based on the modular structure of Pep2-8. Upon encountering PCSK9, TIP undergoes in situ self-assembly at the epidermal growth factor-like domain A (EGF-A) binding domain of PCSK9 to form artificial topological nanostructures (ATNs). The ATNs not only enhance peptide stability and prolong in vivo retention time but also strengthen PCSK9 binding through multivalent synergistic effects. We demonstrate that compared to Pep2-8, TIP forms ATNs which increasing its binding affinity for PCSK9 by approximately 18.7-fold in vitro. In high-fat diet mouse models, TIP significantly increase hepatic LDLR levels (2.0-fold) and reduced LDL-C and TC levels.

Li−L as a multifunctional organic lithium salt can spontaneously attach to the surface of the D-LCO molecules, thus providing replenishment of Li and doping of elemental sodium and sulfur during the regeneration process. Benefiting from the more stable structure of regenerated LCO supported by Na and S elements, the diffusion efficiency of Li ions and electrons can be improved during charging/discharging. As a result, the cell with upcycling LCO cathode exhibits a high capacity of 220.7 mAh g −1 at 0.1 C and retention rate of 89.7 % after 300 cycles at 10 C with a maximum cut-off voltage of 4.6 V.

However, unlike some other, mainly photochromic molecular solar thermal energy storage (MOST) systems, solids that undergo photoinduced [2+2] cycloaddition have not been thoroughly explored for powering reversible actuation, despite that this reaction system carries potential in the heavily strained bonds of the cyclobutane ring. In this study, we propose that broadband-light-induced [2+2] cycloaddition can be used to store energy and actuate dynamic organic crystals by irradiation with visible light. The prototypical material, pyrenylvinylpyrylium tetrafluoroborate ( 1 – PVPyL ), undergoes a topochemical [2+2] cycloaddition induced not only by ultraviolet radiation (365 nm) but also by monochromatic green light (532 nm), red light (620 nm) and broadband visible light in a single-crystal-to-single-crystal (SCSC) manner, causing its crystals to bend. The crystals effectively act as energy depots, where the reverse deformation can be initiated by heating and the stored energy is released via thermal cycloreversion reaction. Given the ubiquity of the [2+2] cycloaddition in the solid state, the current study invites the development of new dimeric MOST architectures that utilize sunlight for energy storage and thermal triggers for energy release.

The extended conjugated system linked by the azo groups facilitates extensive electron delocalization and a low band gap, which endows the PTAP with enhanced electronic conductivity reaching 4.26×10 −3 S m −1 . The azo groups themselves serve as active centers for two-electron transfer, leading to a significant increase in the density of redox-active sites and charge storage efficiency.

Extensive characterization demonstrates that such a unique mortise-tenon stacking structure of 1D-MeCOF inhibits interchain slippage, enhances π-stacking, and maximizing light absorption capabilities. Furthermore, unidirectional carrier transport characteristics of one-dimensional structure can generate a strong photo-induced self-built electric field, which acts as “self-catalysis” to accelerate carrier transport.

However, most conventional RTP polymers are vulnerable to moisture and water, which can disrupt the hydrogen bonding network within the polymer and accelerate the non-radiative decay of triplet excitons of phosphors, leading to the quenching of RTP. Herein, we present a universal strategy to achieve water-resistant RTP polymers by designing amphiphilic block copolymers with microphase-separated structures. Specifically, the rigid hydrophilic phase, which is rich in carboxyl groups, forms hydrogen bonds that suppress non-radiative decay of the chromophores, resulting in RTP. Meanwhile, the hydrophobic phase effectively prevents water molecules from penetrating and disrupting the rigid polymer network. By combining the functions of both the hydrophilic and hydrophobic phases, the resulting RTP copolymers exhibit good water-resistant properties. Even after being immersed in water for one month, the copolymers maintain a green afterglow with a lifetime of 629 ms. Moreover, the water-resistant nature of these RTP polymers has also been demonstrated in potential applications of afterglow displays and anti-counterfeiting.

Herein, a thicker cathode/electrolyte interphase (CEI) is constructed via employing locally concentrated IL electrolytes (LCILEs) to overcome these issues. It is demonstrated that LCILEs facilitate the incorporation of Emim + into the electrode/electrolyte interphases, and, meanwhile, more Al−Cl species deposits are observed in the CEI. The formed CEI effectively prevents the dissolution of poly-selenides, inhibiting their related parasitic reactions. These result in ASeBs, employing the LCILE, to deliver a specific discharge capacity of 218 mAh g −1 at 0.5 A g −1 after 100 cycles at 20 °C, while the cell using the neat ILE only maintains 38 mAh g −1 under the same conditions. Moreover, an Al−S cell operated in LCILEs reaches 578 mAh g −1 at 0.1 A g −1 after 150 cycles, which is also significantly better than 317 mAh g −1 in the neat ILE.

  @article{ , abstract = {Single-mode photodynamic therapy (PDT) based on photochemical reactions is limited by the tumor microenvironment, which reduces the ablation efficiency for solid tumors. Making it vital to seek ways to improve the tumor therapeutic effect. Based on this, we propose a dual-mode intelligent nanotherapeutic system (HAP@BMPns) based on photochemical-biological effects. HAP@BMPns is composed of an acid-responsive high-calcium biomimetic nanomaterial (HAP) and photosensitizer (BMP), which can spontaneously activate photochemical (Type-I PDT) and biological effects for synergistic cancer therapy. HAP@BMPns breaks down upon entering tumor cells under acidic conditions, releasing a large amount of Ca 2+ and BMP. Triggering intracellular Ca 2+ overload, which induces mitochondrial damage, leading to apoptosis. Synchronously, Type-I PDT of BMP under two-photon (800 nm) laser irradiation becomes activated, resulting in enhanced destruction of tumor cells by the photochemical effect. Cell studies have indicated that HAP@BMPns (41.6 μg/mL) exhibits a strong inhibitory efficiency on tumor cells growth, with low (22.4 %) survival rate. However, the individual components, i. e. BMP (5.0 μM) and HAP (41.6 μg/mL) display low inhibitory efficiency with high survival rates (55.9 % and 63.0 % respectively). Therefore, this dual-mode synergistic treatment strategy using acid-triggered photochemical-biological effects significantly enhances the ablation of solid tumors, realizing the synergistic effect.

Our findings reveal that although the SEI film is generally responsible for significantly affecting the HC's capacity, the equally crucial desolvation process must not be overlooked. The trade-off between the two factors is found to be determined by the structural features of HCs. Specifically, in the context of a more ordered HC, the desolvation of ions emerges as the rate-limiting step for Na + transport across the electrode/electrolyte interface, exerting a more pronounced effect rather than the SEI.

These dyes are designed and synthesized with identical hole- and electron-transporting backbones but feature distinct π-bridge groups. They are incorporated into the precursor solution of PbI 2 to facilitate in situ passivation of both interfaces and grain boundaries (GBs) during the formation of the perovskite film (two-step process). These dyes effectively penetrate both buried and upper interfaces, allowing for the passivation of defects originating from the GBs, and both interfaces. This significantly reduces defects while enhancing charge transport properties. Notably, the π-bridge composed of benzo[1,2,5]-thiadiazole in TZR contains unpaired electrons from nitrogen and sulfur atoms. An impressive power conversion efficiency (PCE) of 25.11 % is achieved. This performance significantly surpasses that of TNR-based and pristine devices, achieving PCEs of 24.47 % and 22.88 %, respectively.

In these processes, silanes are employed as a hydride source. Mechanistic insights into these innovative catalytic systems are also elucidated.

Among multi-carbon products, n-propanol is particularly appealing due to its high energy density (~27 MJ/L) and broad industrial applications. However, achieving high selectivity for n-propanol remains a formidable challenge, requiring catalysts capable of facilitating complex reaction pathways and avoiding competing side reactions. In this study, we present a Cu/Cys/Au catalyst architecture that is prepared through a self-assembled monolayer (SAM) that significantly enhances the Faradaic efficiency for n-propanol production. Specifically, Cu substrates are modified with cysteamine SAMs to uniformly anchor a Au 3+ -dimercaptosuccinate complex, which enable uniform Au electrodeposition. The resulting Cu/Cys/Au electrode achieves a Faradaic efficiency of 29.1 % for n-propanol at −1.2 V vs. RHE, representing a significant improvement over conventional Au−Cu electrocatalysts. Control studies reveal the necessity of both Au and Cu for selective n-propanol formation, while mixed SAMs with varying cysteamine and propanethiol ratios allow for precise tuning of Au coverage on Cu.

Typically, the ionic conduction is accelerated by increasing the ionic strength of the electrolyte. However, counterintuitively, polymer films with very high electrochemical impedance demonstrate the opposite effect, i. e. ionic conduction slows down by increasing the ionic strength of the electrolyte. This bimodal nature of ionic conduction was discovered five decades ago and yet the mechanism has remained poorly understood. This minireview explains the long-standing anomaly through the lens of recent advances in nano-confinement electrochemistry. Emerging evidence shows that changes in solvation shells occurs due to the size of the channel through which ionic diffusion takes place. These solvation shells can significantly affect the mobility of ions, their interactions with functional groups of the polymer, and the overall conductivity of the electrolyte. At dimensions only a few nanometers, partially hydrated ions form stronger bonds with polymer slowing down the ionic conduction. Increasing ionic strength will add ion-pairing interactions further reducing ions mobility.

  @article{ , abstract = {The thermocatalytic hydrogenation of CO 2 to ethanol has attracted significant interest because ethanol offers ease of transport and substantial value in chemical synthesis. Here, we present a state-of-the-art catalyst for the CO 2 hydrogenation to ethanol achieved by precisely depositing single-atom Ir species on P cluster islands situated on the In 2 O 3 nanosheets. The Ir 1 -P x /In 2 O 3 catalyst achieves an impressive ethanol yield of 3.33 mmol g −1 h −1 and a turnover frequency (TOF) of 914 h −1 under 1.0 MPa (H 2 /CO 2 =3 : 1) at 180 °C, nearly 8 times higher than that of the unmodified Ir 1 /In 2 O 3 catalyst. Additionally, at a more industrially relevant pressure of 5.0 MPa, the TOF of the Ir 1 -P x /In 2 O 3 catalyst can reach up to 2108 h −1 , surpassing previously reported catalysts. Combined in situ characterization and theoretical studies reveal that the hydrogenation process is significantly enhanced by the Ir 1 -P x entities. Specifically, the Ir atom facilitates CO 2 activation and C−C coupling, while the surrounding P island exhibits exceptional H 2 dissociation ability. These three steps have been found crucial for the CO 2 hydrogenation reaction. This discovery opens new opportunities for the regulation of the microenvironment of current catalysts by providing essential chemical functionalities that enhance intricate and complex reaction processes.}, archive = {J_ANGEW}, author = {Lingyue Liu and Jinjie Liu and Guangchao Li and Xiuwen Shi and Jun Yin and Shourong Zheng and Ka-Fu Yung and Hong Bin Yang and Tsz Woon Benedict Lo}, doi = {10.1002/anie.202422744}, journal = {Angewandte Chemie International Edition}, month = {4}, number = {17}, pages = {e202422744}, shortjournal = {Angew.

Typically, metal surfaces are used in OSS, but the strong interactions distort the intrinsic properties of the synthesized nanostructures and therefore compromise their applicability. Inert surfaces, on the other hand, preserve the nanostructures’ unique properties, but present challenges during synthesis: Activation energies are generally higher than on metal surfaces, hence thermally activated coupling on inert surfaces is severely hampered by competing premature desorption of the reactants. Using the coupling of 1,3,5-tris(4-mercaptophenyl)benzene (TMB) via carbon-sulfur-carbon thioether bonds, we demonstrate that annealing in a noble gas atmosphere instead of in a vacuum kinetically inhibits desorption.

Interestingly, a plateau in storage moduli ( G’ ) was observed for UHMW PDMAm hydrogels with a sufficiently high DP target (>5,000), indicating a transition to the entanglement-dominated regime, with no contribution from crosslinks to the overall modulus, thus indicating the formation of highly entangled hydrogels. These hydrogels exhibit enhanced properties such as high toughness and resistance to swelling despite their vanishingly small crosslinking densities. Furthermore, even when equipped with cleavable crosslinkers, the UHMW PDMAm hydrogels resist degradation due to dense entanglements which act as transient crosslinks preventing the gels from swelling, while sparse covalent crosslinks help to maintain their structural integrity and avoid chain disentanglement.

  @article{ , abstract = {Natural photosynthesis plays a vital role in the supply of energy and oxygen necessary for the survival of biological organisms. The current leading proposal of the O−O bond formation in photosystem II suggests the coupling between the central μ-oxo (O5) and the additional oxygenic ligand (Ox) of the manganese-calcium oxide cofactor. However, the subsequent process through which molecular dioxygen is formed and released remains elusive. In this report, quantum chemical calculations reveal that the O 2 release process is initiated by the cleavage of the Mn−O5 bond, without a preliminary conformational change of the peroxide [O5-Ox] 2− group. Subsequently, the [O5-Ox] moiety is converted from the superoxide to the weakly bound quasi-O 2 where the Mn−Ox bond is cleaved, and after a twist of the quasi-O 2 unit, the free O 2 is ultimately released. Alternative pathways display significantly slower kinetics, due to the lower structural stabilities of the rate-limiting transition states. The cause of the difference is associated with the Jahn-Teller axial orientation and the local ring strain within the Mn cluster.

  @article{ , abstract = {Tuning proton-coupled electron transfer (PCET) is a promising strategy to boost the oxygen reduction reaction (ORR) for hydrogen peroxide (H 2 O 2 ) synthesis, but the slow transmission rate of protons and electrons to active sites remains a significant bottleneck. To address this, we developed an H-bond-driven PCET process based on carbon quantum dot-anchored C 3 N 5 (CQDs-C 3 N 5 ) for piezo-catalytic H 2 O 2 synthesis. CQDs-C 3 N 5 exhibited a remarkable piezo-catalytic synthesis rate of 5025 μmol g −1 h −1 under ambient conditions, surpassing that of most reported piezoelectric materials. This efficiency is attributed to the intermolecular H-bonds between CQDs and C 3 N 5 , which significantly accelerate PCET in the ORR. The piezoelectric-generated charges, from the dipole field of the C 3 N 5 plane, and protons in water, were rapidly transferred to the C rings of CQDs via H-bond networks. This process facilitated the adsorption of oxygen onto the C2 sites adjacent to the carboxyl groups of CQDs, which in turn led to the formation of H 2 O 2 through a rapidly protonated, indirect 2e − pathway. Additionally, a piezo-self-Fenton reaction system was constructed for oxytetracycline-rich wastewater purification, with effectively effects on chemical oxygen demand, antibiotic-resistant bacteria and antibiotic-resistant genes degradation, etc .

Depth-resolved X-ray absorption spectroscopy and depth-profiling X-ray photoelectron spectroscopy were employed. In a thin sample with ~20 nm thickness, uniform oxidation was observed, but a thicker sample with ~80 nm thickness had active oxidized phases close to the surface and an unexpected inactive Co 0 phase concurrently occupying about three-quarters of the CoO x layer in the depth direction, which accounted for the mass activity loss. The formation of Co 0 in the bulk is attributed to the galvanic replacement reaction between CoO x and the metallic Ti substrate, which is not observed on the carbon substrate. Operando Raman spectroscopy demonstrated that the type of cations rather than Cl − impacts the OER performance likely due to their interaction with superoxo species.}, archive = {J_ANGEW}, author = {Hiroki Komiya and Keisuke Obata and Oki Sekizawa and Kiyofumi Nitta and Ke Xu and Melody Wada and Kazuhiro Takanabe}, doi = {10.1002/anie.202501579}, journal = {Angewandte Chemie International Edition}, month = {4}, number = {16}, pages = {e202501579}, shortjournal = {Angew.

  @article{ , abstract = {Silver nanowire (AgNW) electrodes, known for their intrinsic flexibility and tunable optoelectronic properties, have garnered considerable attention for use in flexible organic solar cells (OSCs). However, in conventional OSCs, their low work function (WF) causes energy-level mismatches with classic aqueous hole transport layers (HTLs), while their poor hydrophilicity hinders the formation of optimized HTL morphology and crystallinity, posing challenges to their integration into high-performance OSCs. To address these issues, functionally targeted molecules with a thiol group at one end and strong electron-withdrawing, hydrophilic functional groups at the other are precisely engineered to wrap around the AgNW electrodes. The thiol group facilitates the formation of robust self-assembled molecules (SAMs) on the AgNW electrodes through stable S−Ag chemical bonds at room temperature. The strong electron-withdrawing groups generate notable molecular and interfacial dipoles that effectively raise the WF of AgNW electrodes. Notably, the hydrophilic groups not only improve electrode wettability but also promote strong hydrogen bonding interactions with HTL, leading to substantial improvements in the morphology and crystallinity of the HTL.

  @article{ , abstract = {Achieving efficient long-wavelength organic light-emitting diodes (OLEDs) remains a challenge due to the energy gap law, which leads to increased non-radiative decay rates as the emission wavelength shifts to longer regions. Herein, a strategy of constructing folded three-dimensional architectures is proposed to explore new orange-red thermally activated delayed fluorescence (TADF) emitters with through-space charge transfer characteristics. Innovatively, naphthalene is selected as a bridge to connect O-bridged triphenylamine donor and planar dibenzo[a,c]phenazine acceptor respectively via simple Suzuki–Miyaura Coupling. In this way, a series of rigid orange-red emitters with “U”-shaped, folded “Z”-shaped and “W”-shaped configurations are elaborately constructed by modifying end groups, adjusting the numbers of naphthalene and donor, and regulating the linkage sites. The excited state natures and photophysical properties of the emitters can be effectively regulated and optimized by changing three-dimensional architectures. Finally, the prepared emitter QX36 achieves a lower non-radiative transition rate, a higher radiative rate and a higher photoluminescence quantum efficiency. Solution-processed OLEDs based QX36 present the excellent electroluminescent performance with a maximum external quantum efficiency (EQE) of up to 32.3 % and EQE of 20.6 % at 1000 cd m −2 , which are the leading values of solution-processed orange-red OLEDs.

This reaction integrates SeNEx with CuAAC click chemistry, enabling rapid and regioselective synthesis of 1,4,5-trisubstituted 5-seleno-1,2,3-triazoles with high atom economy and good to excellent yields (65 examples, 50%–95%).

Importantly, a mononuclear σ-bound copper(I)-acetylide Cu1 was synthesized and confirmed to be an efficient catalyst for the SeNEx reaction. This discovery provides crucial mechanistic insights into the preferential reactivity of alkynyl groups toward SeNEx over CuAAC.

However, the exact photophysical process underpinning the persistent-luminescent continues to elude full understanding, and the principles governing the compatibility of hosts and guests remain elusive. In this work, a new type of nonradiative energy transfer mechanism is proposed for the bi-component RTP system. Different from Förster resonance energy transfer or Dexter-type energy transfer, this energy transfer mechanism primarily relies on a triplet exciplex to exchange the electron. This facilitates the formation of triplet excitons that are otherwise difficult to excite directly. An evaluation methodology is devised to gauge the potential of a specific dopant-host combination toward generating pronounced afterglow. According to this framework, the enhancement of the afterglow is proportional to the decrease in the activation energy (Δ G ≠ ) associated with the electron transfer reaction between the dopant and the host. Notably, when the Δ G ≠ too larger, no observable afterglow occurs, as higher Δ G ≠ values significantly impede the electron transfer reaction between the two components. Furthermore, the remarkable dependence of afterglow intensity on the dopant concentration renders the bi-component RTP system highly promising for applications requiring ultra-high sensitivity and broad-spectrum detection capabilities.}, archive = {J_ANGEW}, author = {Liangwei Ma and Yiwei Liu and Xin Jin and Tao Jiang and Lei Zhou and Qiaochun Wang and He Tian and Xiang Ma}, doi = {10.1002/anie.202500847}, journal = {Angewandte Chemie International Edition}, month = {4}, number = {16}, pages = {e202500847}, shortjournal = {Angew.

Herein, an effective bactericidal strategy is developed through enhancing the interfacial electric field (IEF) of S-scheme heterojunctions by an ultrasonication-triggered piezoelectric effect. Hollow barium titanate (hBT) nanoparticles (NPs) were prepared through template etching, followed by in situ assembly of tetrakis (4-carboxyphenyl)porphyrin (TCPP) with Zn 2+ to obtain hBT@ZnTCPP. Both experimental and theoretical evidences support the notion that an IEF is generared from ZnTCPP to hBT. Compared to metalloporphyrins with Fe 3+ , Mn 3+ , Cu 2+ and Ni 2+ , the stronger reduction of ZnTCPP induced by elevation of the orbital energy level of porphyrins after Zn 2+ coordination leads to formation of S-scheme heterojunctions. The ultrasonication-activated polarization field enhances IEF and boosts energy band bending of hBT@ZnTCPP to promote electron-hole separations and ROS generations. Planktonic methicillin-resistant Staphylococcus aureus and their derived biofilms are completely destroyed within 5 min under ultrasonication through up-regulating genes of glucose catabolism and ion transportation and down-regulating genes of ribosomal synthesis and transmembrane transporter.

Here, we designed a core–shell structure of MnS@CdS quantum dots (QDs) to investigate the effect of the internal strain on the Mn emission. Upon pressure processing, an unexpected blueshift of Mn emission was achieved. When the pressure reached a pressure of 2.1 GPa, the conventional redshift of Mn emission reappeared. Remarkable color transition from red to orange and then back to red was observed during pressure treatment. Further analysis revealed that the application of external pressure facilitated the diffusion of Mn atoms into the CdS shell, strengthened host-dopant coupling and mitigated the lattice mismatch rate within the MnS@CdS QDs. These factors resulted in a reduction in phonon coupling strength and an increase in energy transfer efficiency from the exciton of the CdS host lattice to the Mn dopants, thus ultimately accounting for the abnormal blueshift of Mn d−d emission.

Here, a multifunctional polymer interphase with fast kineticsis reported, using poly(phenazine-alt-pyromellitic anhydride) (PPPA) as an electrolyte additive. PPPA, with linear π-conjugated structure and enriched polar pyridine (conjugated cyclic −C=N−) and carbonyl (C=O) groups, preferentially adsorbs on the Zn anode to form a stable solid-electrolyte interphase (SEI) layer in situ. The PPPA SEI is efficient to block direct contact between water molecules and Zn anode, and regulate the interfacial solvation structure and Zn depostion. Importantly, the expanding π-conjugated structure of PPPA is shown to provide abundant 2D open channels for rapid Zn 2+ transport, and the delocalized π electrons form a space electrostatic field to facilitate de-solvation and diffusion of Zn 2+ . As a result, the Zn metal anode with PPPA/ZnSO 4 electrolyte exhibits high Coulombic efficiency of 98.3 % at current density of 20 mA  cm −2 , and excellent cycle lifespan for over 2000 cycles (400 h) at current density 50 mA cm −2 and plating/stripping capacity of 5 mAh cm −2 .

In this study, we report that P 2 O 5 can serve as a post-deposition treatment material to modify the chemical and electrical properties of Sb 2 Se 3 thin films.

Simultaneously, P-doping induced lattice distortion closes the ribbon spacing of (Sb 4 Se 6 ) n , promoting efficient carrier transport from one dimension to three dimensions.

  @article{ , abstract = {Fragment approaches are long-established in target-based ligand discovery, yet their full transformative potential lies dormant because progressing the initial weakly binding hits to potency remains a formidable challenge. The only credible progression paradigm involves multiple cycles of costly conventional design-make-test-analyse medicinal chemistry. We propose an alternative approach to fragment elaboration, namely performing large numbers of parallel and diverse automated multiple step reactions, and evaluating the binding of the crude reaction products by high-throughput protein X-ray crystallography. We show it is effective and low-cost to perform, in parallel, large numbers of non-uniform multi-step reactions, because, even without compound purification, crystallography provides a high-quality readout of binding. This can detect low-level binding of weakly active compounds, which the target binding site extracts directly from crude reaction mixtures. In this proof-of-concept study, we have expanded a fragment hit, from a crystal-based screen of the second bromodomain of pleckstrin homology domain-interacting protein (PHIP(2)), using array synthesis on low-cost robotics. We were able to implement 6 independent multi-step reaction routes of up to 5 steps, attempting the synthesis of 1876 diverse expansions, designs entirely driven by synthetic tractability. The expected product was present in 1108 (59%) crude reaction mixtures, detected by liquid chromatography mass spectrometry (LCMS). 22 individual products were resolved in the crystal structures of crude reaction mixtures added to crystals, providing an initial structure activity relationship map. 19 of these showed binding pose stability, while, through binding instability in the remaining 3 products, we could resolve a stereochemical preference for mixtures containing racemic compounds. One compound showed biochemical potency (IC 50 =34 μM) and affinity (K d =50 μM) after resynthesis.

Atomically dispersed metal catalysts (ADMCs) emerge as promising alternatives to replace commercial noble metals due to their high utilization of active metal atoms, high intrinsic activity, and controllable coordination environments. In this review, the research tendency and reaction mechanisms in ORR are first summarized. The basic principles concerning the geometric size and chemical coordination of two-electron ORR (2e − ORR) catalysts were then discussed, aiming to outline the evolution of material design from 2e − ORR to four-electron ORR (4e − ORR). Subsequently, recent advances in ADMCs primarily investigated for the 4e − ORR are well-documented. These advances encompass studies on M−N−C coordination, light heteroatom doping, dual-metal atoms-based coordination, and interaction between nanoparticle (NPs)/nanoclusters (NCs) and atomically dispersed metals (ADMs).

High-entropy alloys (HEAs), a new class of catalysts, have exhibited exceptional catalytic activities in various electrochemical reactions.

Herein, we prepared a series of quinary FeCoNiCuRu alloys with different ▵S mix values supported on carbon nanofibers as cathode catalysts in Li−CO 2 batteries.

Zeolite nanocrystals within PE provide permanent pores in the liquid phase, enabling physical CO 2 adsorption through an intraparticle diffusion model, as demonstrated by molecular dynamics simulations and in situ spectral analysis. Captured CO 2 spontaneously desorbs under applied reductive potential, driven by the interfacial CO 2 concentration gradient, and is subsequently reduced electrochemically. The high CO 2 concentration in PE enhances mass transfer, and surface ion exchange between Si−OH groups and K + ions on the zeolite surface generates a stronger interfacial electric field, promoting electron transfer steps. This optimized kinetics for mass and electron transfer confers heightened intrinsic activity toward CO 2 electroreduction.

  @article{ , abstract = {Layered manganese-rich oxides (LMROs) are widely recognized as the leading cathode candidates for grid-scale sodium-ion batteries (SIBs) owing to their high specific capacities and cost benefits, but the notorious Jahn-Teller (J-T) distortion of Mn 3+ always induces severe structural degradation and consequent rapid cathode failure, impeding the practical implementation of such materials. Herein, we unveil the “intrinsic distortion against J-T distortion” mechanism to effectively stabilize the layered frameworks of LMRO cathodes. The intrinsic distortion simply constructed by introducing bulk oxygen vacancies is systematically confirmed by advanced synchrotron X-ray techniques, atomic-scale imaging characterizations, and theoretical computations, which can counteract the J-T distortion during cycling due to their opposite deformation orientations. This greatly decreases and uniformizes the lattice strain within the ab plane and along the c axis of the material, thereby alleviating the P2-P′2 phase transition as well as suppressing the edge dislocation and intragranular crack formation upon repeated cycles. As a result, the tailored P2-Na 0.72 Mg 0.1 Mn 0.9 O 2 cathode featuring intrinsic distortion delivers a considerably enhanced cycling durability (91.9 % capacity retention after 500 cycles) without sacrificing the Mn 3+ /Mn 4+ redox capacity (186.5 mAh g −1 at 0.3 C).

  @article{ , abstract = {Carbon dots (CDs) have attracted growing interest in the construction of room-temperature phosphorescent (RTP) materials. However, in the solution phase of CDs, it is still challenging to obtain efficient and stable phosphorescent emission due to the intense quenching effect by dissolved oxygen and solvent molecules. Herein, we report robust phosphorescence in the solution phase, achieved by encapsulating citrate-derived CDs into NaYF 4 nanocrystals via a one-step method of high-temperature coprecipitation. Combined characterizations show that the triplet emission from CDs is related to the abundance of C=O in the CDs, the formation of ionic-bond networks around the CDs, and the spatial confinement and quenching inhibition effects of NaYF 4 nanocrystals. Notably, the transition of CDs@NaYF 4 from hydrophobicity to hydrophilicity can be easily achieved by simple surface modulation of NaYF 4 nanocrystals, which allows the RTP of CDs to be maintained in either polar or nonpolar solvents. In addition, CDs@NaYF 4 exhibits stable afterglow in different pH environments, suggesting its excellent stability. Finally, we demonstrated the application of CDs@NaYF 4 in 3D printing, oily anti-counterfeiting patterns, and cell imaging. Our work can serve the controllable preparation of solution-phase RTP materials and their various applications.}, archive = {J_ANGEW}, author = {Xiaoyan He and Weilan Huang and Yihao Zheng and Xiaokai Xu and Haopeng Wei and Ping Liang and Xianfeng Yang and Chaofan Hu and Xuejie Zhang and Bingfu Lei and Xingcai Zhang and Jianting Ye and Yingliang Liu and Jianle Zhuang}, doi = {10.1002/anie.202423388}, journal = {Angewandte Chemie International Edition}, month = {4}, number = {16}, pages = {e202423388}, shortjournal = {Angew.

Experimental characterizations and first-principles calculations have verified the occurrence of a reversible electrochemical reaction involving a total of 51 electrons among the NTTA ligands, cobalt cations, and Li + ions. Unlike the traditional concept of superlithiation, the three inner aromatic rings are selectively activated by π-aromatic conjugation networks and π π stacking, contributing to a reversible 6-electron pseudocapacitive Li + intercalation reaction. Conversely, the three outer aromatic rings remain inert toward Li + ions. Impressively, the Co-NTTA MOF anode, with selectively activated aromatic rings, delivers a reversible capacity of up to 956 mAh g −1 at 200 mA g −1 and demonstrates exceptional high-rate durability, further supporting a 4.3 V lithium-ion hybrid electrochemical capacitor with high energy/power density.}, archive = {J_ANGEW}, author = {Sha Li and Jiande Lin and Huiqun Wang and Shiyuan Zhou and Xiangyang Guo and Xiao Zhan and Hongwei Tao and Haitao Hu and Zhengyou He and Honggang Liao and Dongping Zhan and Li Zhang}, doi = {10.1002/anie.202423186}, journal = {Angewandte Chemie International Edition}, month = {4}, number = {16}, pages = {e202423186}, shortjournal = {Angew.

Ammonia (NH 3 ) is essential for the synthesis of the compound fertilizer, which was produced by an energy intensive chemical process. Developing efficient and environmental friendly methods to produce ammonia-containing compound fertilizers is crucial and extremely challenging. Here, we present a tandem catalysis system capable of achieving complete conversion of abundant urea into compound fertilizer in industrial-scale reactors by combining electrochemical and subsequent chemical processes. In a typical cycle, with the use of 200 g urea, 1580 g of solid compound fertilizer (KH 2 PO 4 and NH 4 H 2 PO 4 ) and 232 L of pure H 2 are produced without any further separation process. The key to the realization of this system is to precisely control the rate of urea consumption and NO 2 − formation in electrochemical process. By maintaining a precise molar concentration ratio of urea to NO 2 − at 1/2 in electrolyte, urea can completely react with NO 2 − to form N 2 , while CNO − can be converted into NH 4 + to form compound fertilizer in the second step of H 3 PO 4 treatment, achieving complete conversion of urea without by-products formation.

Here, we demonstrate exceptionally stable cation and anion redox behavior in a metastable, cobalt-free layered oxide, Li 0.693 [Li 0.153 Ni 0.190 Mn 0.657 ]O 2 (LLNMO). After 50 cycles at 50 mA/g (~0.2 C), the cathode retains 97.4 % of its initial capacity (222.4 mAh/g) with negligible voltage decay. This remarkable stability is attributed to its metastable O6-type structure (R-3m symmetry) with unique local geometry. The face-sharing connectivity between lithium layers and alternating transition metal (TM) layers effectively suppresses TM migration-induced voltage decay during anion redox. Additionally, the structure balances interlayer cation/cation and anion/anion repulsions, resulting in minimal expansion and contraction during de-/lithiation (<2.3 % along the c -axis) and excellent structural reversibility.

An energetic NH 4 + /H + dual-ion co-intercalation chemistry is enabled, leading to a remarkable gravimetric specific capacity of up to 604 mAh g −1 and long-cycle stability. Combining in-situ Raman spectroscopy and in-situ electrochemical quartz crystal microbalance (EQCM) techniques, we reveal and visualize the conformal reconstruction process and the reversible dual-cation storage mechanism. Density functional theory (DFT) calculation shows that the dual-vacancy coupling helps the dissolution of inert Al from LDHs for enriching active sites.

Here, a novel class of versatile light-driven reconfigurable liquid crystal elastomer (LCE) materials, denoted as PUOLCE, has been developed. The multifunctional dynamic covalent organic photothermal molecules, serving as chain extenders, photothermal agents, and dynamic covalent bond precursors, are chemically bonded into LCEs, thereby endowing the LCEs with photothermal-responsiveness and dynamic properties. The intrinsic photothermal effect of PUOLCE allows the exchange reaction of dynamic oxime-carbamate bonds to undergo rapid welding under near-infrared (NIR) light. Leveraging the NIR-assisted welding strategy, the PUOLCE-based building units are capable of assembling into various complex actuators with new deformation modes. Besides, the assembled actuators can be easily reconfigured to perform different mechanical tasks (e.g., flower blooming, grasping objects, and elevating objects) under NIR illumination.

Theoretical calculations demonstrate that the electron-rich pollutants transfer more electrons to the catalyst surface, inducing the reduction of dissolved oxygen to ⋅O 2 − in the Co-N 2 O 3 microregion. In a practical continuous flow-through application, the system achieved 100 % acetaminophen removal efficiency in 6.5 h, with a hydraulic retention time of just 0.98 s.

  @article{ , abstract = {The difficulty in designing zwitterionic ligands impedes the water-dispersed CsPbX 3 perovskite nanocrystals (NCs) and their application as fast anion exchange (FAE) probes in biosensing. This study proposes a design paradigm for zwitterionic ligands predicated upon revealing the mechanism of the S N 2 reaction between unsaturated alkylamines (Cn′) and haloalkanoic acids (HAAs). Among them, the C=C bond can enhance the nucleophilicity of Cn′ and promote the electrostatic adsorption of HAAs onto Cn′, i.e., the geometric preorganization process, thereby initiating the S N 2 reaction. Moreover, an appropriate “bridge” length enables HAAs to balance the geometric preorganization process and the Sigma hole intensity of the C−Br bond. Zwitterionic ligands derived from oleylamine (C18′) and 5-bromovaleric acid (5-BVA) endow CsPbBr 3 NCs with water dispersibility, an almost 100 % photoluminescence quantum yield, and enhanced surface potential, facilitating the capture of halide ions and driving the FAE reaction. Using AgI nanoparticles (NPs) as latent anion exchangers, a third FAE strategy is presented for multicolor biosensing.

Binary organic solar cells (OSCs) achieved an efficiency of 17.90%, with a non-radiative loss of 0.185 eV, while ternary OSCs reached a remarkable efficiency of 19.52%. Oligomerized electron acceptors, featuring molecular weights akin to polymers and well-defined chemical structures, have emerged as promising candidates for organic solar cells (OSCs) due to their consistent batch-to-batch reproducibility and improved thermal stability. In this study, we developed a series of oligomerized electron acceptors incorporating alkynyl linkages via an efficient Sonogashira coupling reaction between alkyne-substituted Y-type precursors and multi-substituted iodobenzenes. This method produced monomeric (S-Alkyne-YF), dimeric (D-Alkyne-YF), and trimeric (T-Alkyne-YF) configurations, enabling systematic control over molecular size and substituent arms. The alkynyl linkages, characterized by high bond strength and planar geometry, enhanced molecular planarity and aggregation in films, thus facilitating precise control over morphology and phase separation in the photoactive layers. Notably, the inclusion of these linkages effectively suppressed electron-phonon coupling, resulting in reduced non-radiative energy losses and elevated photocarrier lifetime. OSCs based on PM6:T-Alkyne-YF achieved a power conversion efficiency of 17.90%, a low non-radiative energy loss of 0.185 eV, and an open-circuit voltage of 0.943 V. Furthermore, integrating T-Alkyne-YF into the D18:N3 blend yielded an exceptional PCE of 19.52%.

  @article{ , abstract = {Sodium-ion batteries (SIBs), endowed with relatively small Stokes radius and low desolvation energy of Na + , are reckoned as a promising candidate for fast-charging endeavors. However, the C-rate charging capability of practical energy-dense sodium-ion pouch cells is currently limited to ≤1 C, due to the high propensity for detrimental metallic Na plating on the hard carbon (HC) anode at elevated rates. Here, an ampere-hour-level sodium-ion pouch cell capable of 3 C charging is successfully developed via phosphorus (P)-sulfur (S) interphase chemistry. By rational electrolyte regulation, desired P−S constituents, namely, Na 3 PO 4 and Na 2 SO 4 , are generated in the solid-electrolyte interphase with favorable Na + interface kinetics. Specifically, Na + desolvation energy barrier has been greatly lowered by the weak ion-solvent coordination near the inner Helmholtz plane on Na 3 PO 4 interphase, while Na 2 SO 4 expedites charge carrier mobility due to its intrinsically high ionic conductivity. Consequently, an energy-dense (126 Wh kg −1 ) O3-Na(Ni 1/3 Fe 1/3 Mn 1/3 )O 2 ||HC pouch cell capable of 3 C charging (100 % state of charge) without Na plating can be achieved, with a great capacity retention of 91.5 % over 200 cycles.

Experimental results and molecular dynamics (MD) simulations demonstrate that the cation of FCS selectively adsorbs on the electrode surface, optimizing the inner Helmholtz plane (IHP) structure and effectively regulating the surface electric field, thereby promoting homogeneous Li deposition. Simultaneously, the preferential decomposition of the FCS produces a mechanically robust and ionically conductive solid electrolyte interphase (SEI) comprising LiF, Li 3 N, and LiI components.

Nevertheless, organic crystals capable of both photoinduced dynamic effects and static color change are rare, particularly for multi-component cocrystal system. In this study, we first report the construction of charge transfer cocrystal allows their light-induced solid-to-liquid transition and photochromic behaviors to be controlled by trans-stilbene (TSB) as an electron donor and 3,4,5,6-tetrafluorophthalonitrile (TFP) as an electron acceptor. In this case, the dynamic photo-responsive solid-to-liquid phase transition is due to the photoisomerization of TSB under UV light irradiation, while the accumulation of melted droplets during solid-state photochemical process causes mechanical deformation of TSB-TFP cocrystals. The subsequent reversible photochromic behavior is attributed to the emergence of free radicals through a photo-induced electron transfer. Moreover, TSB-TFP microcrystals present typical excitation wavelength dependent emission (EWDE) fluorescence by surfactant-mediated method. This work realizes the dynamic-static photochemical cascade processes in response to UV light irradiation in an organic cocrystal system, providing the effective method for a new type of smart photo-responsive materials.}, archive = {J_ANGEW}, author = {Shuzhen Li and Xueyong Huang and Menghao Xing and Dongpu Zhao and Sitong Li and Xiaoyu Cao}, doi = {10.1002/anie.202500238}, journal = {Angewandte Chemie International Edition}, month = {4}, number = {15}, pages = {e202500238}, shortjournal = {Angew.

The forward-vapofluorochromism occurs when aliphatic amines penetrate guest-free macrocycle crystals to form host-guest complex crystals.

Using engineered dendritic cells (DCs) with surface-bound photosensitizers, we generated reactive oxygen species (ROS) at immune synapses, leading to the targeted death of antigen-specific T cells in close proximity. This process induces lipid oxidation in T cell membranes, triggering ferroptosis-like cell death.

The electron-deficient Lewis acid sites supply coordinatively unsaturated surface sites to adsorb molecular oxygen, and the Brønsted acid sites are liable to donate protons to form hydrogen bonds with the OH groups of alcohols like benzyl alcohol (BA). These coexistent acid sites result in a strong synergistic effect in photocatalytic aerobic oxidation of BA. For example, the conversion of BA to benzaldehyde was found to be 88.6 %, being much higher than those of pristine TiO 2 (14.7 %), N-doped TiO 2 (N-TiO 2 , 24.6 %), sulfated TiO 2 (SO 4 2− / TiO 2 , 35.4 %), and even their sum.

Generally, the aging process is ascribed to the hydrolysis reaction of fluorine-containing electrolyte salt that generates hydrofluoric acid and chemically corrodes the anode surface. Nevertheless, the underlying mechanism about electrolyte degradation, HF generation and surface corrosion remains concealed for various electrolytes. In this work, we employed in situ liquid time-of-flight secondary ion mass spectroscopy to resolve the chemical evolution during high-temperature calendar aging in the bulk of the electrolyte and at the anode/electrolyte interface. Two conventional salts, LiPF 6 and Li bis(fluorosulfonyl)imide (LiFSI), were employed for comparison. We identify that the high-temperature hydrolysis of LiPF 6 preferentially occurs when the anion aggregates ([PF 6 +LiPF 6 ] − ) are attacked by trace H 2 O.

Here, we report a new-type high-entropy electrolyte composed of equal molar amounts of Zn(OTf) 2 and LiOTf, along with equal volumes of H 2 O, triethyl phosphate, and dimethyl sulfoxide, which enhances electrolyte stability by increasing solvation entropy. Specifically, this well-designed high-entropy electrolyte reduces the content of solvated and free water molecules while forming a robust gradient solid-electrolyte interphase on the Zn anode surface, protecting the Zn anode from water-induced corrosion. Moreover, the cationic electrostatic shielding layer on the Zn anode effectively suppresses the “tip effect”, enabling the uniform deposition of Zn. The synergistic effects of this mixed electrolyte effectively leverage the properties of individual additives, significantly extending the cycle life of Zn-metal anodes. Consequently, the resulting Zn//Zn symmetric cell using this high-entropy electrolyte can operate over 8000 h at 1 mA cm −2 and 0.5 mAh cm −2 . To highlight, in a Zn//V 2 O 5 ⋅H 2 O pouch cell, it retains 83.1 % of initial capacity after 420 cycles at 1 A g −1 .

This work demonstrates a rationally designed electron-self-supplied catalytic system capable of generating H 2 O 2 from water and atmospheric oxygen without extra energy input. This catalytic system is made of a ZnO coating containing oxygen vacancies and a Zn substrate. The ZnO catalyst layer obtains electrons from the Zn substrate to synthesize H 2 O 2 . The H 2 O 2 concentration produced by this catalytic system is up to 17.9 mM without any secondary processing. This remarkably high concentration is attributed to the formation of a liquid film on the hydrophilic ZnO surface that promotes the oxygen reduction reaction by accelerating the transfer of oxygen from the ambient air to the catalyst surface.

The theoretical and experimental results showed that the rate-determining step energy barrier for reduction of O 2 to OOH* intermediates was significantly reduced by replacing of bipyridine with biphenyl blocks, changing from 4e to 2e ORR reaction pathway. Also, the donor-acceptor characteristic and narrower optical band gap of TPDA-BDA COF enhanced the electronic conductivity and reduction ability, thus elevating the catalytic activity.

NCMA can form multiple strong interaction modes with LiTFSI through N−H⋅⋅⋅O hydrogen bonding and Li−O/Li−N coordination, which effectively inhibits Li + ions migration at high temperature and increases solubility of LiTFSI in chlorobenzene without acetonitrile and 4-tert-butylpyridine (tBP), fundamentally solving de-doping reaction. In addition, the molecular network with abundant functional groups in DES improves fracture energy of perovskite/spiro-OMeTAD interface and enhances interfacial adhesion via strong chelation with perovskite and Ag electrode. Consequently, benefiting from tBP removement and inhibited ions migration, the optimized PVSCs achieve a power conversion efficiency (PCE) of 25.02 %, and the unencapsulated device retains over 90 % of initial PCE at 85 °C, 40 % RH for 1200 h (ISOS-D-2 standard).

  @article{ , abstract = {Developing advanced electrolytes with high Li affinity is crucial for achieving long-cycling lithium metal batteries (LMBs). However, the strong Li + -solvent interactions in conventional electrolytes often induce difficult Li + desolvation especially under low-temperature conditions, resulting in the formation of fragile electrode interfaces involving solvents, and thus dissatisfactory cycling stability of LMBs. Herein, by introducing various diluents into the lithium hexafluorophosphate in 1, 2-dimethoxyethane electrolyte, we reveal that Li + desolvation is influenced by not only the diluent-solvent interaction but also the diluent-anion interaction. Based on these findings, a diluent selection parameter (DSP), which is calculated based on the product of interaction energies of diluent-solvent/diluent-Li + and diluent-anion/diluent-Li + , is proposed for diluent selection. A diluent with a larger DSP is more favorable for promoting Li + desolvation and improving the low-temperature performance of LMBs. With the rationally selected 1, 2-dichloroethane diluent (DSP=3.95), the Li Cu cell enables high Li reversibility (98.5 % after 300 cycles).

  @article{ , abstract = {Photodynamic therapy (PDT) is a promising treatment that uses light to excite photosensitizers in target tissue, producing reactive oxygen species and localized cell death. It is recognized as a minimally invasive, clinically approved cancer therapy with additional preclinical applications in arthritis, atherosclerosis, and infection control. A hallmark of ideal PDT is delivering disease-specific cytotoxicity while sparing healthy tissue. However, conventional photosensitizers often suffer from non-specific photoactivation, causing off-target toxicity. Activatable photosensitizers (aPS) have emerged as more precise alternatives, offering controlled activation. Unlike traditional photosensitizers, they remain inert and photoinactive during circulation and off-target accumulation, minimizing collateral damage. These photosensitizers are designed to “turn on” in response to disease-specific biostimuli, enhancing therapeutic selectivity and reducing off-target effects. This review explores the principles of aPS, including quenching mechanisms stemming from activatable fluorescent probes and applied to activatable photosensitizers (RET, PeT, ICT, ACQ, AIE), as well as pathological biostimuli (pH, enzymes, redox conditions, cellular internalization), and bioresponsive constructs enabling quenching and activation. We also provide a critical assessment of unresolved challenges in aPS development, including limitations in targeting precision, selectivity under real-world conditions, and potential solutions to persistent issues (dual-lock, targeting moieties, biorthogonal chemistry and artificial receptors).

The rotation of the imidazole ring, which is thermally possible due to a central C−C bond with a weakened π-component, changes both the charge separation and diradical character depending on the dihedral angle, as quantum mechanical calculations indicate. By varying the bulkiness of substituents at the imidazole-based NHO, it was possible to obtain different diphospha-indenylide species with different rotation angles in the solid state and hence varying diradical character.

Among various TM-coated Zn (TM@Zn) electrodes, Cu@Zn exhibits the highest reversibility and structural stability, attributed to the optimal interaction between Cu and Zn. The heteroatomic interaction-dependent electrochemical performance parallels the Sabatier principle. Morphological analyses reveal that bare Zn anodes display detrimental etching pits during stripping, which is different from the uniform dissolution for Cu@Zn electrodes. During subsequent plating, the conductive interface serves as a secondary current collector for uniform Zn deposition in Cu@Zn, thus demonstrating a bifunctional nature.

Steady State Free Precession (SSFP) NMR collects the signal in a steady state regime, allowing 100’s of acquisitions in the timespan of a single traditional NMR scan. Unfortunately, data truncation from SSFP leads to artifacts and spectral broadening with Fourier transform, hindering interpretation. When non-Fourier based time-domain analysis is used, namely, complete reduction to amplitude frequency tables (CRAFT), limitations of SSFP are eliminated while sensitivity gains are retained. This work introduces the combined approach, then applies it for the measurement of PFCs in environmental and biological samples. In all cases, the approach reduces analysis time from many hours to minutes and/or greatly increases the range of compounds detected. For example, when PFOA was spiked into human blood, the detection limit improved ~50-fold vs standard NMR, while in a standard mixture, the approach detected compounds missed by LC-MS/MS.

The system provides a CO 2 -to-ethanol conversion efficiency (CTE) of 92 %. Furthermore, this method also allows the conversion of CO 2 through direct air capture (DAC), making it a rapid and versatile method for both dissolved and gaseous CO 2 .}, archive = {J_ANGEW}, author = {Alina Meindl and Daniel Heffernan and Jürgen Kudermann and Nicole Strittmatter and Mathias O.

Theoretical calculations and in situ spectroscopy disclose that the curvature of the carbon support helps to shorten the bond length of Fe−N, spatially redistributing the charges around the Fe and thereby lowering the d-band center toward optimal adsorption for oxygenated species. The Fe SA/NhcC catalyst displays an ultrahigh half-wave potential of 0.926 V for ORR and a small potential difference of 0.686 V for bifunctional ORR/UOR.

  @article{ , abstract = {Electrolyte chemistries are crucial for achieving high cycling performance and high energy density in lithium metal batteries. The localized high-concentration electrolytes (LHCEs) exhibit good performance in lithium metal batteries. However, understanding how the intermolecular interactions between solvents and diluents in the electrolyte regulate the solvation structure and interfacial layer structure remains limited. Here, we reported a new LHCE in which strong hydrogen bonding between diluents and solvents alters the conformation and polarity of “flexible” solvent molecules, thereby effectively regulating the solvation structure of Li + ion and promoting the formation of robust electrode interfaces. The endpoint H of the “flexible” chain O-CH-CH 3 of the 2,5-dimethyltetrahydrofuran (2,5-THF) solvent and the F of the benzotrifluoride (BTF) diluent can form strong hydrogen bonds, which expand the maximum bond angle of the 2,5-THF molecule from 119° to 123°. The expanded bond angle increases the steric hindrance of the 2,5-THF molecule and decreases its polarity. This leads to an increase in the anion content within the solvation structure, which in turn enhances the performance of both the lithium metal anode and the sulfurized polyacrylonitrile (SPAN) cathode. As a result, the lithium metal anode shows a Coulombic efficiency (CE) of as high as 99.4 %. The assembled Li||SPAN battery based on our developed LHCE exhibits impressive stability with an average CE of 99.8 % over 700 cycles.

We show how to intentionally guide UstD towards generality through multi-generational directed evolution using substrate-multiplexed screening (SUMS). Mutations outside of the active site that impact catalytic function were immediately revealed by shifts in promiscuity, even when the overall activity was lower. By re-targeting these distal residues that couple to the active site with saturation mutagenesis, broadly activating mutations were readily identified. When analyzing active site mutants, SUMS identified both specialist enzymes that would have more limited utility as well as generalist enzymes with complementary activity on diverse substrates.

  @article{ , abstract = {Oximes are important intermediates for various chemicals synthesis such as pharmaceuticals, among which one vital precursor for producing neurological disease, antimicrobial and anticancer agents is piperidone oxime (PDO). Compared with conventional thermocatalytic method, it's more attractive to synthesize PDO via green electrocatalytic technology especially utilizing waste nitrogen oxides gas as nitrogen source. However, there are great challenges in catalyst design for high-efficiency electrosynthetic oxime due to the low electron transport rate and multiple competing reactions. Herein, we propose an interfacial coordination strategy based on metal–organic frameworks (MOF) electrocatalyst for the first time to promote oxime electrosynthesis, by building Zn−O bridges between graphite felt (GF) and zeolitic imidazolate framework (ZIF-7/CGF). Specially, ZIF-7/CGF delivers a Faraday efficiency (FE) of 75.9 % with yield up to 73.1 % for 1-methyl-4-piperidone oxime, which is far superior to the catalyst without Zn−O bridges (a FE of 10.7 % and yield of 10.3 %). In-depth mechanism study shows that the introducing Zn−O bridges can promote the electron transfer and induce Zn sites transforming into distorted tetrahedron (Zn-N 3 O) coordination mode, which benefits for intermediates adsorption and conversion. The developed strategy presents wide universalities towards various oximes electrosynthesis and adapts to other MOF materials (ZIF-8, ZIF-4).

Upon external disturbance, the composite gels undergo an instant and reversible soft-rigid state transition, simultaneously turning on intense fluorescence and activating ultralong afterglow emission with a maximum lifetime of 877.15 ms.

Here, to modulate COF catalytic performance, we introduce tunable catalytic vertex wall chemistry by introducing diverse triazine and thiophene units. The catalytic vertex wall approach allows the fine-tuning of electronic surface states, leading to improved intermediate adsorption characteristics and accelerated ORR activity. Remarkably, the engineered COF achieved a half-wave potential of 0.76 V, surpassing COFs modified by linker or linkage strategies. Theoretical calculations suggest that this enhanced activity arises from the strong binding affinity of OOH* intermediates to carbon atoms adjacent to the thiophene vertex, facilitating OOH* reduction to a O 2 molecule, which is the rate-limiting step of the ORR.

This study presents a novel strategy to stabilize SSBUs by tuning the π-stacking geometry of conjugated building blocks, facilitating the creation of hydrogen-bonded frameworks with tailored architectures for demanding gas separation. Specifically, parallel-displaced π–π stackings of aromatic heterocycles bearing carboxyls promote the formation of SSBUs bridged by ammonium cations [NH 4 + ] 8 [COO − ] 8 ( SSBU-4 ), enabling the assembly of hydrogen-bonded frameworks with permanent porosity and structural diversity influenced by the solvent effect. Comparatively, the non-heterocyclic building units exhibit geometrically- or energetically-unfavorable π stackings, resulting in fragile frameworks that collapse after removing disordered guests.

In this work, a Pt 2 L 4 cage capable of catalyzing the cyclization reaction of an alkynoic tosyl amide is orthogonally coupled to a diacid-catalyzed carbodiimide-hydration cycle. This new Pt-catalyzed cyclization reaction is demonstrated to exhibit electronic regulation by inclusion of different guest effectors. The orthogonal diacid-catalyzed carbodiimide hydration cycle produces transiently diverse guests that influence the rate of the Pt-catalyzed cyclization reaction to different extents. Further complexity can be introduced to the system through displacing the transiently-formed, weakly bound anhydride guest with the stronger binding fumaronitrile, affecting the catalytic rate to a larger extent for the duration of the orthogonal reaction cycle. The modulation of a Pt-catalyzed cyclization reaction can thus be regulated transiently over the course of the reaction— either up- or down-regulating the turnover frequency (TOF)—via coupling with a temporally controllable orthogonal process.

Aptamer-based chimeras hold great promise as membrane protein degraders, however, their degradation efficacy is often hindered by the limited structural stability and the risk of off-target effects due to the non-covalent interaction with target proteins. We here report the first design of a covalent aptamer-based autophagosome-tethering chimera (CApTEC) for the enhanced autophagic degradation of cell-surface proteins, including transferrin receptor 1 (TfR1) and nucleolin (NCL). This strategy relies on the site-specific incorporation of sulfonyl fluoride groups onto aptamers to enable the cross-linking with target proteins, coupled with the conjugation of an LC3 ligand to hijack the autophagy-lysosomal pathway for targeted protein degradation. The chemically engineered CApTECs exhibit enhanced on-target retention and improved structural stability. Our results also demonstrate that CApTECs achieve remarkably enhanced and prolonged degradation of membrane proteins compared to the non-covalent designs. Furthermore, the CApTEC targeting TfR1 is combined with 5-fluorouracil (5-FU) for synergistic tumor therapy in a mouse model, leading to substantial suppression of tumor growth.

In contrast to unconfined counterparts, the nanoconfined composite catalysts retain high degradation efficiency when exposed to various concentrations of NOM and anions, even in real water samples.

Taking advantage of the cross-linked ion-conductive paths constructed by hierarchical pore structures, the PMG-GPE achieves a high ions conductivity of 1.9 mS cm −1 . Additionally, the robust mechanical properties of PMG-GPE effectively suppress dendrite growth and penetration, outperforming crystal MOF-based electrolytes. The prepared Li symmetric batteries with PMG-GPE demonstrate a high critical current density of 5.1 mA cm −2 (two times higher than crystal MOF-electrolytes) and stable cycling for over 6000 hours without short circuits. Furthermore, a Li/PMG-GPE/LFP half-cell exhibits exceptional capacity retention of 83.12 % after 1400 cycles.

The diffusion of C and N atoms results in the formation of uniformly distributed TMISS nanocrystals, with an average diameter of ~1.9 nm, thus maximizing atomic utilization. The unique crystalline-amorphous heterojunction interface enhances electrocatalytic stability. Furthermore, the electronic regulation of metal sites by interstitial C and N atoms not only optimizes the adsorption-dissociation process in hydrogen evolution reaction (HER), but also accelerates the surface reconstruction of hydroxyl oxides to enhance the oxygen evolution reaction (OER) activity. As a result, the as-prepared coating achieved overpotentials of only 62 mV and 237 mV for the HER and OER at 10 mA cm −2 in alkaline electrolytes, and exhibited excellent OWS performance and long-term stability at high current densities.

This method maximizes the utilization of silicon and aluminum content from sludge, prevents metal agglomeration, and precisely regulates the chemical environment of Fe active sites. As a result, the S-NCCs promote a transition from nonradical to hybrid radical/nonradical reaction mechanisms, significantly enhancing ROS efficiency, stability, and pollutant degradation rates.

A theoretical framework is established, elucidating the volcanic relationship between asymmetry degree and ORR activity by constructing a series of Fe-based SAC models doped with non-metal atoms (B, P, S, Se, and Te) in the first or second coordination sphere, which aligns with Sabatier principle. The predicted ORR activity of Fe asymmetric active moieties is then experimentally validated using asymmetry degree. The combined computational and experimental results suggest that single-atom moiety with a moderate asymmetry degree exhibits optimal intrinsic ORR activity, because breaking the square-planar symmetry of FeN 4 can alter the electronic population of the Fe 3d-orbital, thereby optimizing the adsorption-desorption strength of intermediates and thus enhancing the intrinsic ORR activity.

We quantificationally unveil a dependence of the UOR activation barrier on the coverage of photogenerated surface high-valent Ni-oxo species (Ni IV =O) by employing operando PEC spectroscopic measurements and theoretical simulations. The strong attraction between Ni IV =O and adsorbed urea facilitates their N−O coupling while weakening the C−N bonding within urea, manifesting as the decreased UOR activation energy from 0.74 to 0.41 eV when the surface coverage of Ni IV =O is enhanced from zero to full, corresponding to more than two orders of magnitude enhancement for the UOR rate. Furthermore, an industrial-grade photocurrent density of 100 mA cm −2 is achieved at a potential as low as 1.08 V RHE by stimulating the Ni IV =O accumulation under 10 Suns, which is 300 mV lower than the potential required for most reported electrochemical counterparts.

The multimode optical spectroscopies confirm that this electrolyte engineering is able to effectively regulate the solvation of LiPSs to initiate a radical-assisted conversion pathway and control three-dimensional (3D) Li 2 S electrodeposition to boost sulfur utilization. More importantly, the dynamic evolution of cathode–electrolyte interphase, featuring with S-/P-containing species, is also assessed by both distribution of relaxation times technology and X-ray photoelectron spectroscopy, which can suppress the passivation of Li 2 S to enhance conversion reversibility.

Inhibition of both self- and IAPP-cross-seeded αSyn amyloidogenesis could thus interfere with PD pathogenesis.

Now, in light of considerable developments in the study of metal complexes dissolved in ionic liquids with their negligible vapor pressures, more detailed studies of the composition at the liquid/gas interface became possible. These investigations revealed pronounced surface enrichment and segregation effects of high relevance for practical applications. This article reviews recent advancements in tailoring the interfacial composition of ionic liquid-based catalytic systems. A particular focus is dedicated to surface enrichment phenomena, and a variety of parameters are presented for deliberate control of the local concentration of the complexes at the surface, that is, the nature of the ligands, the bulk concentration, the temperature, and the nature of the IL solvent. As experimental methods, angle-resolved X-ray photoelectron spectroscopy (ARXPS) and vacuum-based pendant-drop surface tension measurements were applied.

We applied two strategies: mixed-linker synthesis and linker installation. In the mixed-linker approach, we incorporated an auxiliary linker, TPTB, which resembles PPTB, during synthesis to improve the framework's stability.

Currently mechanical recycling typically leads to downcycling, while the environmental footprint of chemical recycling is often unacceptable.

Very small changes in macromolecular structures, thermal and mechanical properties were observed, after as many as six repeated mechanical recycling cycles, showing that a wide processing window could be the key for closing the mechanical recycling loop. Facile, time and energy efficient closed-loop chemical recycling into products with identical performance to original ones was also realized, thanks to the abundant free volume and accessible ester-functionalities.

  @article{ , abstract = {Intrinsically stretchable organic solar cells (IS-OSCs) are emerging as promising candidates for powering next-generation wearable electronics. However, developing molecular design strategies to achieve both high efficiency and mechanical robustness in IS-OSCs remains a significant challenge. In this work, we present a novel approach by synthesizing a dimerized electron acceptor (DY-FBrL) that enables rigid OSCs with a high power conversion efficiency (PCE) of 18.75 % and a crack-onset strain (COS) of 18.54 %. The enhanced PCE and stretchability of DY-FBrL-based devices are attributed to its extended π-conjugated backbone and elongated side chains. Furthermore, we introduce an innovative polymerized acceptor (PDY-FL), synthesized via the polymerization of DY-FBrL. While PDY-FL-based devices exhibit a slightly lower PCE of 14.13 %, they achieve a significantly higher COS of 23.45 %, representing one of the highest PCEs reported for polymerized acceptors containing only flexible linkers. Consequently, IS-OSCs fabricated using DY-FBrL and PDY-FL achieve notable PCEs of 14.31 % and 11.61 %, respectively. Additionally, the device stretchability improves progressively from Y6 (strain at PCE 80% =11 %), to DY-FBrL (strain at PCE 80% =23 %), and PDY-FL (strain at PCE 80% =31 %).

  @article{ , abstract = {Molecular recognition and detection of small bioactive molecules, like neurotransmitters, remain a challenge for chemists, whereas nature found an elegant solution in the form of protein receptors. Here, we introduce a concept of a dynamic artificial receptor that synergically combines molecular recognition with dynamic imine bond formation inside a lipid nanoreactor, inducing a fluorescence response. The designed supramolecular system combines a lipophilic recognition ligand derived from a boronic acid, a fluorescent aldehyde based on push-pull styryl pyridine and a phenol-based catalyst. The recognition ligand specifically captures dopamine inside lipid nanodroplets and thus triggers imine bond formation with the aldehyde, producing the emission color change. The rational design of the fluorescent aldehyde, the catalyst, and the recognition ligand allows dramatic acceleration of the imine bond formation required for rapid sensing of dopamine. The nanoprobe enables dopamine detection with micromolar sensitivity and singe-nanoprobe imaging of dopamine gradients through its robust two-color ratiometric response. It displays remarkable selectivity without the interference of competing biogenic primary amines and biological media: blood serum, plasma, urine and cell lysate.

Here, inspired by nacre's “brick-and-mortar” structure, we develop mixed matrix type composite membranes in which dominant crystalline ZIF-8 nanoparticles (bricks) are interconnected by ultrathin zinc coordination polymer interlayers (mortar) via self-assembling. Driven by coordination bonds between Zn 2+ from precursor colloid and branched polyethyleneimine (PEI), a zinc coordination polymer network is formed to connect ZIF-8 nanoparticles through interactions between Zn 2+ of coordination polymer and surface terminal groups on ZIF-8 nanoparticles, thus eliminating intercrystalline void defects and providing a highly selective H 2 transport pathway. Meanwhile, the micropores and large cavities in ZIF-8 allow fast H 2 transport.

This study presents a novel guest-induced crystallization (GIC) strategy, guided by thermodynamic calculations, to develop porous hydrogen-bonded organic frameworks (HOFs) using structurally challenging tetrazole building units. Thermodynamic principles are established from the crystal structure data and the density functional theory calculation of the formation energy ( ΔE ). This provides criteria to identify available guests in GIC, enabling the successful discovery of a hidden HOF that is kinetically challenging to crystallize. Furthermore, the potential application for p -xylene (PX) separation is predicted by analyzing the ΔE of guest-induced HOFs. A high PX selectivity (PX/ m -xylene=6.1, PX/ o -xylene=7.2, and PX/ethylbenzene=4.1) is achieved through selective inclusion of PX from C8 aromatic isomers within the guest-induced HOFs. Significantly, the guest-free HOF ( HOF-PX-a ), bearing PX-templated cavities derived from molecular imprinting, shows a record-high PX/ethylbenzene selectivity (21.7) in liquid adsorption. This work elucidates the underpinning self-assembly rules of GIC for HOF construction, providing exciting new opportunities for the predictable assembly of PCMs for molecular recognition and target-specific separations.}, archive = {J_ANGEW}, author = {Yi Su and Qiang Gao and Xiaojun Ding and Gang Ye}, doi = {10.1002/anie.202423932}, journal = {Angewandte Chemie International Edition}, month = {3}, number = {13}, pages = {e202423932}, shortjournal = {Angew.

  @article{ , abstract = {Precise control of assembled structures of quantum dots (QDs) is crucial for realizing the desired photophysical properties, but this remains challenging. Especially, the one-dimensional (1D) control is rare due to the nearly isotropic nature of QDs. Herein, we propose a novel strategy for controlling the 1D-arrangement range of cubic perovskite QDs in solution based on the morphological modification of a supramolecular polymer (SP) template. The original template with a short and tangled fibrous structure is prepared in a low-polarity solvent mixture via self-assembly of a naphthalenediimide-functionalized cholesterol derivative with an adhesion group for QDs. Mixing this template with QDs leads to the co-aggregation into short-range 1D-arrays of QDs on the templates. Notably, subsequent heating and cooling of the co-aggregate solution forms longer-range 1D-arrays of QDs with lateral growth, where arranged QDs are sandwiched between reconstructed SP templates. Furthermore, the longer-range 1D-array of QDs is achieved via an alternative route involving the pre-organization of templates into longer and dispersed fibers by heating and cooling of the original template, succeeded by co-assembly with QDs. Finally, we reveal continuous fluorescence resonance energy transfer between 1D-arranged QDs by an in-depth analysis of the photoluminescence decay curves.}, archive = {J_ANGEW}, author = {Amrutha Manoj Lena and Mitsuaki Yamauchi and Hideyuki Murakami and Naoki Kubo and Sadahiro Masuo and Kyohei Matsuo and Hironobu Hayashi and Naoki Aratani and Hiroko Yamada}, doi = {10.1002/anie.202423912}, journal = {Angewandte Chemie International Edition}, month = {3}, number = {13}, pages = {e202423912}, shortjournal = {Angew.

Selective oxidation or cleavage of HEWL occurs under physiological conditions by producing reactive oxygen species (ROS) in presence of ascorbate (Asc) as a reducing agent. The outcome of the oxidative reaction can be tuned by varying the concentration of V 6 -OH to result either in selective oxidation of the amino acid side chains or peptide bond cleavage.

Surface prelithiation, particularly through the molten salt method, is critical in enhancing spent cathode repair during high-temperature annealing. However, the sluggish Li + transport kinetics, which predominantly relies on thermally driven processes in the traditional molten salt methods, limit the prelithiation efficiency and regeneration of spent cathodes. Here, we introduce a special molecular configuration (benzoate) into molten salts that facilitates rapid Li + transport to the surface of LiNi 0.5 Co 0.2 Mn 0.3 O 2 (NCM) via a quasi-Grotthuss topochemistry mechanism. This approach effectively avoids the phase transitions that could adversely degrade the electrochemical performance due to insufficient lithiation during the repair process. Computational and experimental analyses reveal that the system enables fast Li + migration through the topological hopping of benzoate in organic lithium salt, rather than relying solely on thermally driven diffusion, thereby significantly improving the prelithiation and repair efficiency of spent NCM cathodes. Benefiting from the quasi-Grotthuss Li + topochemistry transport, the degraded structure and Li vacancies in the spent cathode are effectively eliminated, yieding the regenerated cathode with good cycling stability comparable to commercial counterparts.

Consequently, the NF/Ni 3 N−Cu with Cu nanoclusters intimate anchoring presents record NH 3 yield rate of 1.19 mmol h −1 cm −2 and Faradaic efficiency of 98.7 % at −0.3 V vs. RHE, being on par with the state-of-the-art ones.

CO 2 capture driven by electrochemical reactions is attractive because the operation is carried out at normal temperature and pressure and involves a simple input system using electrical energy. Although promising metal complexes with high CO 2 fixation performance have been reported, there are few studies on systems that combine electrochemical reactions and metal complexes. Here, we demonstrated stable CO 2 fixation-release cycles using an electrochemical system with trinuclear Zn(II) complex (Zn 3 L ) as the CO 2 fixative and an ionic liquid as a supporting electrolyte for the stable operation. This system showed a faster CO 2 fixation rate than that of an aqueous alkaline solution at the same concentration. Continuous release and refixation of CO 2 were achieved by decomposition and reconstruction of the complex structure induced by H + and OH − supplied from a bipolar membrane equipped in the electrolytic cell. The CO 2 fixation-release cycle was demonstrated even for dilute CO 2 (450 ppm) in air, where the CO 2 capture rate reached approximately 46 % of CO 2 contained in the air under an air flow condition of 200 mL ⋅ min −1 .

The structural and functional diversity of PoTeMs is biosynthetically elaborated from lysobacterene A by pathway-specific cyclizing and modifying enzymes. This results in diverse core structure decoration and cyclization patterns. However, approaches to directly edit the PoTeM carbon skeleton do currently not exist. We thus set out to modify the PoTeM core structure by exchanging the natural l -ornithine-derived building block by l -lysine, hence extending macrocycle size by an additional CH 2 group. We developed streamlined synthetic access to lysobacterene A and the corresponding extended analog and achieved cyclization of both precursors by the cognate PoTeM cyclases IkaBC in vitro. This chemo-enzymatic approach corroborated the catalytic competence of IkaBC to produce a larger macrolactam yielding homo-ikarugamycin. We thus engineered the adenylation domain active site of IkaA to directly accept l -lysine, which upon co-expression with IkaBC delivered a recombinant bacterial homo-ikarugamycin producer.

This area of research has attracted much attention in recent decades due to its importance in energy storage and conversion. Herein, we report the synthesis of two imine-linked isoindigo-based covalent organic networks I-TTA and I-TG (I=Isoindigo, TTA=4,4′,4′′-(1,3,5-triazine-2,4,6-triyl)-trianiline, TG=triamino-guanidinium hydrochloride salt). By introducing two amine core units with different planarity, such as triazine and ionic guanidinium units, we control the morphology, crystallinity, and corresponding electrocatalytic properties of the materials. The combination of isoindigo dialdehyde with a planar triazine core, leads to the formation of thin, highly crystalline, planar two dimensional (2D) nanosheets covalent organic framework (COF), I-TTA whereas its combination with ionic non-planar guanidinium core leads to an amorphous covalent organic polymer (COP), I-TG with a fibrous morphology. The sheet-like crystalline I-TTA COF shows better electrocatalytic activity compared to the amorphous fibrous I-TG COP. I-TTA exhibits a current density of 10 mA cm −2 at an overpotential of ~134 mV for HER (in 0.5 M H 2 SO 4 ) and ~283 mV for OER (in 1 M KOH).

  @article{ , abstract = {Controlling trap depth is crucial to improve photocatalytic activity, but designing such crystal structures has been challenging. In this study, we discovered that in 2D materials like BiOCl and Bi 4 NbO 8 Cl, composed of interleaved [Bi 2 O 2 ] 2+ and Cl- slabs, the trap depth can be controlled by manipulating the slab stacking structure. In BiOCl, oxygen vacancies (V O ) create deep electron traps, while chlorine vacancies (V Cl ) produce shallow traps. The depth is determined by the coordination around anion vacancies: V O forms strong σ bonds with Bi-6p dangling bonds below the conduction band minimum (CBM), while those around Cl are parallel, forming weak π-bonding. The strong re-hybridization makes the trap depth deeper. In Bi 4 NbO 8 Cl, V Cl also creates shallow traps, but V O does not produce deep traps although Bi-6p orbitals are also forming strong σ bonding. This difference is attributed to the difference of the energy level of CBM. In both cases, the CBM consists of Bi-6p orbitals extending into the Cl layers. However, these orbitals are isolated in BiOCl, but those in Bi 4 NbO 8 Cl are bonded with each other between neighboring [Bi 2 O 2 ] 2+ layers. This unique bonding-based CBM prevents the formation of deep electron traps, and significantly enhances H 2 evolution activity by prolonging the lifetime of highly reactive free electrons.}, archive = {J_ANGEW}, author = {Akira Yamakata and Kosaku Kato and Takafumi Ogawa and Kanta Ogawa and Makoto Ogawa and Daichi Kato and Chengchao Zhong and Akihide Kuwabara and Ryu Abe and Hiroshi Kageyama}, doi = {10.1002/anie.202419624}, journal = {Angewandte Chemie International Edition}, month = {3}, number = {13}, pages = {e202419624}, shortjournal = {Angew.

Reports regarding the influence of CND on the properties of, for example, N -hetero-π-conjugated chromophores are scarce. Thus, our incentive was to design a CND model that features phenazine (P-CND) – a well-known N -hetero-π-conjugated chromophore – to investigate the influence of the CND matrix on its redox chemistry as well as photochemistry. The scope of our work was to go beyond investigating the electrochemical properties of the resulting P-CND by shedding light onto differences relative to nano-aggregates of phenazine (PNZ NA ), which served as reference. In particular, chemical as well as electrochemical reduction of PNZ NA initiated a reaction cascade that affords the primary reduction intermediate, that is, the reduced and protonated (PNZ-H)⋅. In accordance with existing literature, the final product of a bimolecular disproportionation was 5,10-dihydrophenazine (PNZ-H 2 ). Reducing P-CND also resulted in the formation of (PNZ-H)⋅. But, no evidence for a subsequent bimolecular disproportionation was gathered. Instead, (PNZ-H)⋅ as an integrative part of P-CND was found to be actively involved in a H 2 generation reaction.

Compared to ethanol, the electrocatalytic CO 2 RR current with triethanolamine increases by more than three times.

This alkylcarbonate can release the bound CO 2 molecule for activation at the Fe site upon its interaction with FeTPP. In addition to shuttling CO 2 , alkylcarbonates can also provide protons to assist the C−O bond cleavage.

  @article{ , abstract = {Non-ionic “super-hydrophilic” polymers generally possess strong non-fouling characteristics and, therefore, can suppress non-specific and unwanted interactions with blood proteins when attached to in vivo nanomedicine ranging from drug or gene delivery to diagnostics. In this contribution, we revitalize a protected alcohol functionalized 2-oxazoline monomer, 2-acetoxymethyl-2-oxazoline, that was first reported almost fifty-five years ago and explore the possibility of making “super-hydrophilic” poly(2-oxazoline)s for biomedical applications. The synthesis of the 2-acetoxymethyl-2-oxazoline monomer and its cationic ring-opening homopolymerization and copolymerization kinetics are reported. The monomer showed unanticipated and intriguing reactivity during homopolymerization as it very slowly polymerizes at low temperature while the polymerization rate constant at high temperature is amongst the highest known values. Additionally, first order kinetic plots for the copolymerisation of AcOMeOx with EtOx at high temperature revealed that AcOMeOx is incorporated at a slower rate than EtOx confirming its lower nucleophilicity, while EtOx was accelerated in the copolymerization indicating chain-end activation by the ester side-chains. Subsequently, controlled hydrolysis of the resulting poly(2-acetoxymethyl-2-oxazoline) (PAcOMeOx) generates the alcohol (−OH) side chain functional poly(2-hydroxymethyl-2-oxazoline) (PHOMeOx). The relative hydrophilicity of PHOMeOx was analyzed and compared with the previously reported most hydrophilic poly(2-oxazoline)s, such as poly(2-methoxymethyl-2-oxazoline) and poly(2-methyl-2-oxazoline), revealing that PHOMeOx is the most hydrophilic poly(2-oxazoline) reported to date. Finally, the cytocompatibility of these different hydrophilic polymers with MDA-MB-231 breast cancer cells was explored where all polymers revealed high cytocompatibility. Most importantly, strong anti-fouling properties of the most hydrophilic PHOMeOx against serum protein were observed during the cell association studies. Hence, the “super-hydrophilic” and anti-fouling PHOMeOx might be an interesting candidate to be explored in the area of polymeric drug and gene delivery as well as anti-fouling surfaces.}, archive = {J_ANGEW}, author = {Somdeb Jana and Milan Roels and Meike N.

Herein, a polyfunctional biomolecular, vitamin B 6 , is introduced into the traditional aqueous electrolyte for customizing the functional AEI and fine-regulating the interfacial coordination environment of zinc ions. Specifically, the preferential anchoring of pyridine nitrogen enables trace vitamin (2.0 g L −1 ) to construct a robust AEI and suppress corrosion reactions.

This is primarily because the Ru-top sites, which are potential H adsorption sites, are recessive catalytic sites, compared with the adjacent Ru-hollow sites that have a strong ΔG *H . To promote the transformation of Ru-top sites from recessive to dominant catalytic sites, interstitial Si atoms are implanted into the hollow sites.

This strategy led to the synthesis of two new optical crystals: noncentrosymmetric CsAs 2 O 3 Br and centrosymmetric CsAs 4 O 6 Br. By incorporating highly optically active [AsO 3 ] 3− units into the classical 2D [Be 2 BO 3 F] ∞ − framework, we facilitated the self-assembly of [As 2 O 3 ] ∞ layers, forming a densely packed and highly ordered structure that enhances macroscopic optical activity. CsAs 2 O 3 Br exhibited an extraordinary second-harmonic generation (SHG) response, 20.5 times stronger than KH 2 PO 4 (KDP), while CsAs 4 O 6 Br demonstrated exceptional birefringence (0.26 at 546 nm), setting new performance benchmarks among KBBF analogs. Theoretical analyses reveal that these superior properties arise from the efficient alignment and high density of self-polymerized functional units.

  @article{ , abstract = {The binding free energy of hydrogen-bonded complexes is generally inversely proportional to the solvent dielectric constant. This occurs because the solvent-accessible surface area of the complex is always smaller than that of the individual subsystems, leading to a reduction in solvation energy. The present study explores the potential for stabilizing hydrogen-bonded complexes in a solvent with higher polarity. Contrary to the established understanding, we have demonstrated that the hydrogen-bonded complex (CH 3 CH 2 COOH⋅⋅⋅2,4,6-trimethylpyridine) can be better stabilized in a solvent with higher polarity. In this case, a significant charge transfer between the subsystems results in an increased dipole moment of the complex, leading to its stabilization in a more polar solvent. The expected inverse relationship between binding free energy and solvent dielectric constant is observed when the charge transfer between the subsystems is low. Thus, the magnitude of the charge transfer between subsystems is possibly the key factor in determining the stabilization or destabilization of H-bonded complexes in different solvents.

  @article{ , abstract = {Currently, the development of polymeric hole-transporting materials (HTMs) lags behind that of small-molecule HTMs in inverted perovskite solar cells (PSCs). A critical challenge is that conventional polymeric HTMs are incapable of forming ultra-thin and conformal coatings like self-assembly monolayers (SAMs), especially for substrates with rough surface morphology. Herein, we address this challenge by designing anchorable polymeric HTMs (CP1 to CP5). Specifically, coordinative pyridyl groups are introduced as side-chains on poly-triarylamine (PTAA) backbone with varied contents by copolymerization method, resulting in chemical interactions between polymeric HTMs and substrates. The strong interaction allows them to be processed into ultra-thin, uniform, and robust hole-transporting layers through employing low-concentration solutions (0.1 mg mL −1 , vs. 2.0–5.0 mg mL −1 for conventional PTAA), greatly decreasing charge transport losses. Moreover, upon systematically tuning the pyridyl substitution ratio, the energy levels, surface wetting, solution processability, and defect passivation capability of such anchorable HTMs are simultaneously optimized. Based on the optimal CP4, we achieved highly efficient inverted PSCs with power conversion efficiencies (PCEs) up to 26.21 %, which is on par with state-of-the-art SAM-based inverted PSCs.

  @article{ , abstract = {Designing high-performance electrocatalysts with superior catalytic activity and stability is essential for large-scale hydrogen production via water electrolysis. Heterostructure nanoarrays are promising candidates, though achieving both high activity and stability simultaneously, especially under high current densities, remains challenging. To this end, we have developed a cascade reaction process that constructs a series of heterostructure nanoarrays with rich heterointerfaces. This process involves treating nickel foam (NF) with molten KSCN and transition metal salts. Initially, NF reacts with KSCN to form Ni 9 S 8 nanoarrays and S 2− ions, which are subsequently captured by transition metal ions to form sulfides that are directly integrated onto the nanoarrays, resulting in abundant heterointerfaces. Both experimental and theoretical results indicate that these rich heterointerfaces significantly enhance the interfacial interaction between Ni 9 S 8 and RuS 2 within the nanoarrays (termed RH-Ni 9 S 8 /RuS 2 ), markedly improving both the intrinsic activity and stability for the hydrogen evolution reaction (HER). Impressively, the RH-Ni 9 S 8 /RuS 2 demonstrates exceptional HER performance, achieving a low overpotential of just 180 mV at 1000 mA cm −2 and maintaining stability for up to 500 h under such high-current-density conditions.

Herein, we report a nickel-catalyzed divergent, one-step double hydrocyanation of 1,3-butadiene to produce either adiponitrile or 2-methylglutaronitrile in high regioselectivity. The key to this success lies in the highly tunable binding pockets of the bidentate phosphite ligands, which creates a geometrically defined coordination space around the nickel center. The first hydrocyanation that produces either the linear or branched alkenyl nitrile was identified as the selectivity-determining step. Organometallic studies confirm the formation of well-defined diphosphite nickel diene complexes in solution, and the role of ligands in dictating regioselectivity was further rationalized by DFT computations.

This study demonstrates that by tuning the electrolyte structure with the introduction of propylene glycol methyl ether (PM) as a co-solvent and ZnI 2 as an electrolyte additive, and significant improvements at both electrodes could be achieved. Experimental and theoretical calculations reveal that the larger polar −OH and C−O−C electron-donating groups in the PM molecule can donate electrons for the redox reaction of I − /I 3 − . Its role as a redox mediator improves the reversibility of the sulfur cathodic transformation. Additionally, the dipole moment induced by the hydroxyl groups in PM enhances electron transfer from the zinc anode to the electrolyte and promote the decomposition of anions (OTF − ), improving the interfacial stability of the zinc anode.

This strategy designs plasmids with a DNA lesion (8-oxoG and O 6 -MeG) site-specifically installed within the ribozyme encoding region, generating active hammerhead ribozyme for mRNA degradation due to transcriptional mutagenesis, whereas DNA repair yields a single-base mismatch in the ribozyme to abrogate its activity.

The dual emission centers also introduce excitation wavelength-dependent properties for the molecules. In addition, three-band emission covering the visible and near-infrared regions can be shown when two or three kinds of metal ions are simultaneously doped into the radical system driven by the ligand-metal-metal charge transfer (LMMCT). Interestingly, visible light can quickly quench the radical emission of systems, thus realizing a dynamic luminescence.

In contrast, chemiluminescent theranostic agents without the requirement of real-time light excitation can address the issue of tissue autofluorescence, which however have been rarely reported for photodynamic therapy (PDT), not to mention less oxygen-dependent Type-I PDT. In this work, we synthesize near-infrared (NIR) chemiluminophores with the specific binding towards human serum albumin (HSA) to form chemiluminophore-protein complex for cancer detection and photodynamic therapy. Interestingly, after the complexation with HSA, the chemiluminescence (CL) intensities of chemiluminophores are enhanced by over 10-fold; meanwhile, the photodynamic process switches from Type-II (singlet-oxygen-generation dominated) to Type-I (superoxide anion and hydroxyl radical dominated), while the previously reported activated chemiluminophore with non-specific HSA binding can't switch photodynamic process.

  @article{ , abstract = {Morphology control of the photoactive layer is crucial for achieving high-performance organic solar cells (OSCs), yet it remains a significant challenge in this field. One effective approach is the additive strategy, which fine-tunes the morphology of the photoactive layer. However, the underlying mechanisms governing the impact of different types of additives from liquid, solid, to volatile solid, on the bulk heterojunction morphology and device performance are not fully understood. Herein, we present an aggregation regulation strategy for acceptor molecules by incorporating three novel isomeric additives: 4-bromo-1,2-dichlorobenzene (LCB), 1-bromo-2,4-dichlorobenzene (SCB), and 2-bromo-1,4-dichlorobenzene (VCB) into the blend active layer. This approach optimizes the bulk heterojunction morphology and enhances the photovoltaic performance of OSCs. Our results reveal that these additives induce stepwise regulation of acceptor molecule aggregation during film formation. The liquid additive LCB primarily extends solvent evaporation time, effectively preventing excessive aggregation, while the solid additive SCB significantly shortens the aggregation period during the film evolution, resulting in the most compact molecular π–π stacking. Furthermore, the volatile solid additive VCB fine-tunes the intermolecular interactions and crystallization within the active layer, promoting optimal molecular self-assembly and aggregation for ideal molecular stacking.

Consequently, a-SrRuPtO x H y NBs displays superior HOR performance with a mass activity of 7.5 A/mg Pt+Ru , 25 and 5 times of that of SrRuPt(OH) x NBs and commercial PtRu/C, respectively, and long-lasting stability. Besides, a peak power density of 750 mW/cm 2 and a specific power of 14.8 W/mg Pt+Ru have been achieved for a-SrRuPtO x H y NBs at a low loading of 0.05 mg Pt+Ru /cm 2 , surpassing many reported HOR catalysts. Mechanism investigation indicates that Pt and Ru are present in oxide/hydroxide forms and H in a-SrRuPtO x H y NBs participates in HOR. Ab initio molecular dynamics (AIMD) simulations and density functional theory (DFT) calculations show that there are three catalytic mechanisms participating in a-SrRuPtO x H y NBs, which all exhibit low catalytic barrier and highly improved HOR efficiency.

  @article{ , abstract = {As the number of chiral ring molecules in chiral polyrotaxane increases, the number of possible stereoisomers exponentially increases. Consequently, the selective synthesis of a specific stereoisomer becomes much more challenging. To address this problem, we co-crystallized poly(ethylene glycol) and a diastereomeric ring molecule, pillar[5]arene, in the solid state. The co-crystallization formed polypseudorotaxanes with a high diastereomeric excess (ca. 88 % de ), meaning that polypseudorotaxanes containing ( S , pS ) stereoisomer pillar[5]arene rings were synthesized selectively. By contrast, in solution and evaporation systems, the selectivity remained low (ca. 10 % de ). The results suggested that the packing effect by the co-crystallization contributed to the denser assembly of ring molecules on the polymeric chain, resulting in the diastereoselective formation. High diastereoselectivity was also observed even in higher-molecular-weight poly(ethylene glycol)s. These selectivities arose from the cooperative effects of the ring molecules on the polymeric chain, which were supported by calculating the stabilization energy.}, archive = {J_ANGEW}, author = {Kiichi Yasuzawa and Keisuke Wada and Shixin Fa and Yuuya Nagata and Kenichi Kato and Shunsuke Ohtani and Motohiro Mizuno and Tomoki Ogoshi}, doi = {10.1002/anie.202420115}, journal = {Angewandte Chemie International Edition}, month = {3}, number = {12}, pages = {e202420115}, shortjournal = {Angew.

  @article{ , abstract = {Bacterial biofilms are major contributors to persistent infections and antimicrobial resistance, posing significant challenges to treatment. However, obtaining high-resolution structural information on native bacterial biofilms has remained elusive due to the methodological limitations associated with analyzing complex biological samples. Solid-state NMR (ssNMR) has shown promise in this regard, but its conventional application is hindered by sensitivity constraints for unlabeled samples. In this study, we utilized high-sensitivity Dynamic Nuclear Polarization (DNP) ssNMR to characterize native Pseudomonas fluorescens colony biofilms. The ~75-fold sensitivity enhancement provided by DNP enabled structural characterization without isotope labeling or chemical/physical modification. We successfully collected 1D 13 C/ 15 N, and 2D 1 H− 13 C, 1 H− 15 N and 13 C− 13 C ssNMR spectra within seconds, minutes or hours, facilitating the identification and quantification of biofilm extracellular matrix (ECM) components. Additionally, DNP ssNMR allowed quantitative detection of both flexible and rigid biofilm components by favorable freezing conditions. This study represents the first application of ultrasensitive DNP ssNMR to characterize a native bacterial biofilm, significantly expanding the capabilities of ssNMR for analyzing the composition and structure of a wide array of in vitro and ex vivo biofilms.

Herein, we report a methanol-water mediated dual assembly pathway strategy for simultaneous construction of P and M helices in one-component chiral system. The conformation of l -phenylaniline derivates (LBpyF) is controlled to folded state in CH 3 OH due to the hydrogen bonds as well as C−H⋅⋅⋅π interaction between LBpyF and CH 3 OH. Addition of H 2 O into above CH 3 OH solution of LBpyF results in the simultaneous occurrence of two self-assembly pathways and double networks of P and M helices were therefore formed, due to the synchronous process of 1) self-assembly of folded LBpyF into M-helices and 2) H 2 O induced unfolding of folded LBpyF molecules followed by self-assembly of them into P-helices. The bipyridine core, phenyl ring, amide unit all adapted into different stacking modes in M-helices and P-helices, and energy analysis indicated that the minority M-helices were more thermodynamically favored products.

However, the fabrication of microvasculature is still challenging using existing strategies. Here, we developed a general PRINting Cell Embedded Sacrificial Strategy (PRINCESS) and successfully fabricated microvasculatures using degradable DNA biolubricant. This is the first demonstration of direct cell printing to fabricate microvasculature, which eliminates the need for a subsequent cell seeding process and the associated deficiencies. Utilizing the shear-thinning property of DNA hydrogels as a novel sacrificial, cell-laden biolubricant, we can print a 70 μm endothelialized microvasculature, breaking the limit of 100 μm. To our best knowledge, this is the smallest endothelialized microvasculature that has ever been bioprinted so far. In addition, the self-healing property of DNA hydrogels allows the creation of continuous branched structures. This strategy provides a new platform for constructing complex hierarchical vascular networks and offers new opportunity towards engineering thick tissues. The extremely low volume of sacrificial biolubricant paves the way for DNA hydrogels to be used in practical tissue engineering applications.

Through judicious introduction of a pseudo -equatorial fluorine [C(sp 3 )-F] adjacent to the anomeric position, β-selective fucosylation can be achieved with a range of diverse acceptors (>50 : 1): the selectivity of this process can be inverted through changes in the donor scaffold.

  @article{ , abstract = {Strong polar molecular cages have recently emerged as novel functional building units for high-performance infrared nonlinear optical (IR NLO) crystals. However, these highly polar molecular cages often arrange themselves in a way that cancels out their polarity, leading to a more energetically stable state. As a result, most cage crystal formations tend to crystallize in centrosymmetric space groups, which conflicts with the primary requirement for NLO crystals. Herein, we address the challenge of polar molecular cage arrangement through bipolar-axis-symmetry coupling strategy, utilizing classical NLO parent compounds. By substituting the C 3v symmetric [B 3 O 6 ] groups with polar C 3v symmetric [PAs 3 S 3 ] cages within the β -BBO polar aixs lattice, we successfully synthesized a new compound, PAs 3 S 3 (PAS), which exhibits a consistent arrangement of polar molecular cages — crucial for maximizing NLO performance. Additionally, due to the non-covalent interactions among [PAs 3 S 3 ] polar molecular cages, PAS demonstrates an unexpectedly strong second harmonic generation (SHG) about 8 times that of AgGaS 2 , along with a significant band gap of 2.75 eV. Furthermore, PAS exhibits remarkable stability against air and moisture. These findings validate our design strategy and position PAS as a promising candidate for applications in IR NLO crystals.}, archive = {J_ANGEW}, author = {Chao Wang and Chensheng Lin and Xin Zhao and Shunda Yang and Tao Yan and Shenghao Fang and Lingli Wu and Ning Ye and Min Luo}, doi = {10.1002/anie.202421825}, journal = {Angewandte Chemie International Edition}, month = {3}, number = {11}, pages = {e202421825}, shortjournal = {Angew.

The regulation of intermolecular H-bonds is regarded as one of the most effective approaches to enable efficient Li + transport, while the practical performances are hindered by the electrochemical instability of free H-bond donors and the constrained mobility of highly ordered H-bonding structures. To overcome these challenges, we develop a surface-confined disordered H-bond system with stable donor-acceptor interactions to construct a loosened chain segments/ions arrangement in the bulk phase of PEO-based electrolytes, realizing the crystallization inhibition of PEO, weak coordination of Li + and entrapment of anions, which are conducive to efficient Li + transport and stable Li + deposition.

The approach integrates genome mining and the reversible, chemoselective tagging of furyl residues, utilizing their unique Diels–Alder reactivity, for mass-spectrometry-guided identification of candidate compounds. By employing the rhizonin Fua synthase as a bioinformatic handle and through heterologous reconstitution of Fua biosynthesis, we identified previously unknown Fua biosynthetic pathways in diverse bacterial phyla, including actinomycetes, cyanobacteria, actinobacteria, and γ-proteobacteria, suggesting that Fua-containing peptides are remarkably widely distributed. Metabolic profiling by reversible tagging facilitated the detection of Fua-containing metabolites in their native producers. The successful adaptation of this method for solid support enabled the direct enrichment of furyl-substituted peptides from complex mixtures.

  @article{ , abstract = {Nanopores offer significant advantages in biosensing. Conventional nanopore sensors require probe modification within the pore, and there are two major obstacles: inhomogeneity of probe modification within the pore, and distortion of the detection signal due to the uncontrollable dynamics of the target within the pore. Here, we constructed a cell-sensing analogue nanopore (CeSa-nanopore), by coating the outer surface of the nanopore with cell membrane. The inhomogeneity of probe modification and the uncontrollable kinetics of target-probe binding were also addressed. Specific cells are selected to prepare CeSa-nanopore, for example, cells with high expression of angiotensin-converting enzyme 2 (ACE2) are used to achieve the detection of SARS-CoV-2. When SARS-CoV-2 binds to CeSa-nanopore the surface potential changes, causing a change in the ionic current, thus enabling its detection with a detection rate of 100 %. In addition, the detection of different proteins, such as follicle-stimulating hormone (FSH), can be achieved by changing the cell membrane coating. The identification of cancer cells in ascites can also be achieved by utilizing homologous targeting between cancer cells. Importantly, the use of CeSa-nanopores for the detection of these targets eliminates the need for pre-processing and significantly reduces detection time.}, archive = {J_ANGEW}, author = {Jun Dai and Yuxin Hu and Weiyong Liu and Hong Liu and Shixuan Wang and Fan Xia and Xiaoding Lou}, doi = {10.1002/anie.202421721}, journal = {Angewandte Chemie International Edition}, month = {3}, number = {11}, pages = {e202421721}, shortjournal = {Angew.

Traditional PROTACs with high molecular weight were first divided into two smaller druglike precursors capable of self-assembling to form functional PROTACs through a bioorthogonal reaction. Then, optimal CLIPTACs precursors ( W4 and Z2 ) were encapsulated individually into cyclic RGDfC-peptide-modified liposomes to prepare Nano-CLIPTACs, enabling tumor-targeted delivery and subsequent in situ self-assembly to form PROTACs WZ42 within tumor cells. The degradation abilities of Nano-CLIPTACs in vitro and in vivo were further verified using a key oncology target, anaplastic lymphoma kinase (ALK), validating the safety, efficacy and “anti-hook effect” of this strategy.

We propose that this reactivity is driven by the pyrosulfate sites SZO , which open under mild conditions to transiently form adsorbed SO 3 and sulfate groups. This adsorbed SO 3 is a very strong Lewis acid that binds 15 N-pyridine or triethylphosphineoxide (TEPO) (Δ E ads >−39 kcal mol −1 ), reacts with Ph 3 CH to form Ph 3 C + , and mediates H/D exchange in dihydroanthracene- d 4 . DFT studies show that pyrosulfate sites open with a modest 26.1 kcal mol −1 barrier to form the adsorbed SO 3 and sulfate in the presence of a tetramer of propylene. Hydride abstraction from the tertiary C−H in this model is exothermic and subsequent β-scission forms cleaved products.

To address this issue, this study innovatively proposes a dynamic passivation strategy that utilizes a pre-passivator to gradually release active additives during the thermal crystallization process of perovskite films. By leveraging the principle of energy minimization, these timely-released additives can interact precisely and selectively with the high-energy defect sites generated during crystallization, thus facilitating efficient additive utilization and in situ real-time defect passivation. Through analysis of crystallization kinetics and carrier dynamic, it is demonstrated that this dynamic passivation approach significantly improves film quality and prolongs carrier lifetime, outperforming traditional pre-mixing tactics.

  @article{ , abstract = {The crosstalk of transition metal ions between the metal oxide cathode and Zn anode restricts the practical applications of aqueous zinc-ion batteries (ZIBs). Herein, we propose a decoupled electrolyte (DCE) consisting of a nonaqueous-phase (N-phase) anolyte and an aqueous-phase (A-phase) catholyte to prevent the crosstalk of Mn 2+ , thus extending the lifespan of MnO 2 -based ZIBs. Experimental measurements and theoretical modelling verify that trimethyl phosphate (TMP) not only synergistically works with NH 4 Cl in the N-phase anolyte to enable fast Zn 2+ conduction while blocking Mn 2+ diffusion toward anode, but also modifies the Zn 2+ solvation structure to suppress the dendrite formation and corrosion on Zn anode. Meanwhile, the A-phase catholyte effectively accelerates the cathode reaction kinetics. The as-developed Zn|DCE|MnO 2 cell delivers 80.13 % capacity retention after 900 cycles at 0.5 A g −1 .

  @article{ , abstract = {Methane (CH 4 ), a major greenhouse gas and abundant carbon resource, presents significant challenges in catalysis due to its high symmetry and thermodynamic stability, which tend to cause over-oxidation to CO 2 . Traditional catalysts require high temperatures and pressures to facilitate CH 4 conversion, constrained by their rigid structures which lack the flexibility needed for optimizing complex reaction steps. This study introduces a novel Cu embedded liquid metal catalyst (Cu-LMC) based on gallium alloys, characterized by dynamic, self-adaptive structures that provide enhanced catalytic performance and selectivity. Our findings reveal that Cu-LMC achieves a high methane conversion to methanol yield (5.9 mol⋅g Cu −1 ⋅h −1 ) with a selectivity of 82 %. The results show that mild surface oxidation significantly boosts the catalytic performance of Cu-LMC by increasing active copper sites through the formation of a Cu−O−Ga configuration while preserving the catalyst‘s structural flexibility. In situ X-ray Photoelectron Spectroscopy (XPS) and X-ray Absorption Fine Structure (XAFS) analyses, along with ab initio Molecular Dynamics (AIMD) simulations, demonstrate that the Cu-LMC enables self-adaptive structural adjustments that lower methanol desorption energy and increase the energy barrier for by-product formation, optimizing the overall methane conversion process.

  @article{ , abstract = {The microenvironment is recognized to be as crucial as active sites in heterogeneous catalysis. It was found that the catalytic activity of a set of chemical reactions can be significantly influenced by the confined space of carbon nanotubes (CNTs), with some reactions showing superior activity, while others experience a negative impact. The rational design of confined catalysis must rely on the accurate insights of confined microenvironment. However, the structural complexity of confined catalysts and the interaction with microenvironment hinders the deciphering of chemical origins behind experiments. In this work, Grand-canonical Monte Carlo (GCMC) simulations are conducted for confined catalysis in CNTs at various reaction atmospheres, accelerated by machine learning potentials. The statistical outcomes of GCMC simulations corroborate a general feature that the electronic interaction (binding energy) inside CNTs is weaker than outside cases. By using Random Forest (RF) model, we ascertain that the shortening of the bond lengths of catalysts within the confined space is the dominant factor, resulting in the weakened binding energy and the downshift of the d -band center.

Comprehensive investigations revealed that adjusting the binder ratio in the bicomponent ( Ga-MOC and Ni-en ) co-assembly process allows precise control over nanostructure length and evolution by influencing both the kinetics and thermodynamics of the assembly. At higher concentrations, this assembly forms a hydrogel above a critical binder ratio. Furthermore, the binder′s ratio significantly influences the viscoelastic strength of the hydrogels by modulating the connectivity between the MOCs through hydrogen (H)-bonding. Intriguingly, the hydrogels gradually transformed into crystals without any external stimuli, with different timescales regulated by the binder ratio.

At the microscopic level, we employed double solvents to manipulate the intermolecular packing of microporous tetrahedral [4+6] imine cages (CC1 and CC3), resulting in pore channel orientation. Concurrently, at the mesoscopic level, convective flow in the double-solvent system directed the spatial distribution of nuclei species, followed by diffusion limited growth, leading to the directional formation of single-crystal microtubes. By precisely controlling the direction of convective flow, the nanocages were successfully organized into 2D and 3D single-crystal microtube arrays while maintaining oriented micropores.

  @article{ , abstract = {Time-dependent afterglow colored (TDAC) behavior differs from static afterglow by involving wavelength changes, enabling low-cost, high-level encryption and anti-counterfeiting. However, the existing carbon dot (CD)-based TDAC materials lack a clear mechanistic explanation and controllable wavelength changes, significantly hindering the progress of practical applications in this field. In this study, we synthesized CDs composites with customizable tunable TDAC wavelengths across the visible region. Furthermore, we elucidated the underlying mechanism of TDAC that exhibits sequential weakening and relative strengthening of long- and short-wavelength afterglow centers. This phenomenon arises due to strong emission with a short lifetime originating from long-wavelength thermally activated delayed fluorescence (TADF), along with weak emission having a longer lifetime originating from short-wavelength phosphorescence. The presence of surface-rich carboxyl groups on CDs determines the short-wavelength afterglow in their dispersed state while their high conjugation degree governs the long-wavelength afterglow in their aggregated state. Additionally, appropriate doping levels of CDs enhance color change phenomena during afterglow. Finally, by embedding CDs into different rigid matrix, the range of afterglow changes can be tailored arbitrarily within the visible light region. Leveraging these exceptional TDAC characteristics has allowed us to successfully develop advanced 4D coding technologies that facilitate multi-mode anti-counterfeiting and dynamic information encryption.}, archive = {J_ANGEW}, author = {Yongqiang Zhang and Yue Liu and Xueyan Ren and Yihong Kang and Shurong Ding and Siyu Lu}, doi = {10.1002/anie.202421421}, journal = {Angewandte Chemie International Edition}, month = {3}, number = {11}, pages = {e202421421}, shortjournal = {Angew.

  @article{ , abstract = {Poly(ethylene terephthalate) (PET), with an annual production of exceeding 70 million tons, is mainly utilized in disposable fields and subsequently contribute to severe environmental pollution. Conventional chemical recycling, which typically involves depolymerizing polymer into monomers, is limited due to the intricate recycling process, excess using unrecyclable solvents and low polymer conversion. Inspired by protein's molecular switches, we propose a novel polymer-to-polymer recycling strategy based on polycondensation principles upcycling waste PET to high-value recyclable poly(ethylene- co -1,4-cyclohexanedimethanol terephthalate) derivatives containing molecular switches. Upon deactivating the molecular switch, an acidification reaction occurs within the system, leading to a rapid and controllable reduction in molecular weight due to the imbalance of reactive group. Conversely, activating the molecular switch triggers a ring-closing reaction that detaches acid anhydrides, bringing about equal molar ratio of groups and thereby facilitating an increase in molecular weight. By simply incorporating a molecular switch into condensation products based on melt polycondensation, closed-loop recycling capability is achieved without necessitating excessive organic solvents or complex depolymerization processes.

However, the underlying mechanisms remain unclear as many of the I-antigen sequences are undefined and inaccessible. In this study, we developed a highly efficient orthogonal-group-controlled approach to access site-selectively I-branched poly-LacNAc chains.

This approach enabled the rapid preparation of a diverse library of 41 linear and branched poly-LacNAc glycans from a single precursor.

Novel NO donors with tunable kinetics suited for simple thermal generation are needed to realize such iNO delivery systems. Here we report the development of a new class of NO donors based on N -trityl 3,6-dihydro-1,2-oxazines. We show that amorphous solid dispersions of these molecules in porous polymers exhibit consistent, thermoresponsive NO release in good yields when heated above 90 °C in the presence of a carrier gas. We further demonstrate that these donors undergo NO release in aqueous media at 37 °C. Collectively, this work adds a new class of NO donor to the basis set of known NO-genic molecules and establishes a potential chemical basis for a low-power, small-footprint iNO delivery system.}, archive = {J_ANGEW}, author = {Shuxiao Li and Nathan W.

Electrocatalytic evaluations showed that single Pt sites located inside of the channels exhibited higher kinetic activity compared to those anchored outside. The in situ spectroscopic analysis revealed that local reconstruction of Pt−Cl breaking and potential-induced anion transport occurred more effectively inside the channels. The superior anion transportability and kinetic activity of the inside-channel active sites also facilitated *OH desorption during the ORR process outperforming their outside-channel counterparts.

Here, we describe a chemoenzymatic strategy that readily provided a panel of twenty-one sulfated and sialylated ganglio-oligosaccharides. It is based on the chemical synthesis of a core tetra- and pentasaccharide that are equipped with the orthogonal protecting groups allyloxycarbonate (Alloc), levulinate ester (Lev) and t -butyldimethylsilyl ether (TBS). Selective removal of one or more protecting groups followed by sulfation of the resulting alcohol(s) and deprotecting gave several ganglio-oligosaccharides. Compound lacking an internal sialic acid could be prepared by exposing several derivatives to a sialidase. Compounds having an unmodified terminal galactoside could enzymatically be sialylated to give hybrid structures, which could be further extended to provide 2,8-sialosides. The synthetic glycans were printed as a microarray which was used to examine ligand requirements of a series of glycan-binding proteins including antibodies, toxins, galectins and siglecs.

  @article{ , abstract = {Insufficient ionic conductivity and elevated desolvation energy barrier of electrolytes limit the low-temperature applications of lithium metal batteries (LMBs). Weakly solvating electrolytes (WSEs), with limited lithium salt dissociation capability, are prone to desolvate and drive anion-rich aggregates (AGGs). However, significant AGGs result in increased viscosity and low ionic mobility, contributing to battery failure at low temperatures (≤−20 °C). Here, we propose and achieve a transformation of WSEs’ solvation structures from AGGs to contact ion pairs (CIPs) through modulating the overall solvation capability, thereby achieving the balance between weak Li + - solvent interactions and desired ion migration kinetics. Remarkably, CIPs-dominated electrolyte shows a ten-fold increase in ionic conductivity compared to conventional WSEs. The Li||LiFePO 4 (LFP) battery achieves more than 1400 cycles with 86.9 % capacity retention at 5 C. The practical 1.2 Ah LFP pouch cell delivered 69 % of the capacity at 25 °C when cycled at −40 °C.

  @article{ , abstract = {Lipid nanoparticles (LNPs) based messenger RNA (mRNA) therapeutics hold immense promise for treating a wide array of diseases, while their nonhepatic organs targeting and insufficient endosomal escape efficiency remain challenges. For LNPs, polyethylene glycol (PEG) lipids have a crucial role in stabilizing them in aqueous medium, but they severely hinder cellular uptake and reduce transfection efficiency. In this study, we designed ultrasound (US)-assisted fluorinated PEGylated LNPs (F-LNPs) to enhance spleen-targeted mRNA delivery and transfection. Through liquid-to-gas phase transition, we enabled the controlled shedding of fluorinated PEG lipids from F-LNPs, facilitating cellular uptake, membrane fusion, and mRNA release. In vivo results demonstrated that US-assisted F-LNPs increased mRNA transfection approximately 4.0-fold in the spleen following intravenous administration. Notably, the F-LNPs achieved effective mRNA delivery to antigen-presenting cell subsets, such as dendritic cells, macrophages, and B cells. The targeted delivery of full-length ovalbumin-encoding mRNA vaccine induced significant CD8 + T cell response and exhibited excellent therapeutic effect against the ovalbumin-transduced B16F10 tumor model.

Potential resolutions to the Kauzmann paradox rely on an ideal glass transition, however, this limits the interpretation of T k as an equilibrium critical point rather than an instability. Focusing on entropy, statistical mechanics and non-equilibrium dynamics becomes a key tenet in resolving this paradox. Expansion in phase space beyond 2D and consideration of T k as a non-equilibrium critical point is necessary to understand the extent of liquid relaxation beyond T k . In this review, we provide an entropic perspective of the relaxation behavior of supercooled liquids, associated expanded phase diagram, and the potential resolution to the Kauzmann paradox.

  @article{ , abstract = {Ultrasound-mediated reactive oxygen species (ROS) generation is pivotal in specifically inducing pyroptosis of tumor cells. However, the effectiveness of pyroptosis is generally hindered by the constraints of ROS generation efficiency. Herein, a new porphyrin-based metal–organic framework (Fe(TCPP)-MOF) was rationally designed via an innovative dual-solvent strategy to amplify ROS generation for ultrasound-controlled pyroptosis. The crystal structure of Fe(TCPP)-MOF was elucidated by continuous rotation electron diffraction technique, revealing its regular and rigid conformation. The porphyrin molecules were precisely oriented and firmly confined within the scaffold, effectively restricting intramolecular motion. The ample distance of 6.8 Å between two porphyrin molecules, combined with the interaction region indicator visualization, confirmed the absence of π–π stacking interactions in the Fe(TCPP)-MOF framework, thereby avoiding the aggregation-caused quenching effect. Furthermore, the permanent porosity and expansive surface area of Fe(TCPP)-MOF enhanced its interaction with oxygen. These ingenious structural features endowed Fe(TCPP)-MOF with a unique ability to generate a large amount of singlet oxygen under ultrasound activation. Meanwhile, the impetus of ultrasound also accelerated the rate of the Fenton reaction catalyzed by iron ions, significantly boosting the generation of hydroxyl radicals. Benefiting from the dual amplification of ROS, Fe(TCPP)-MOF could efficiently induce tumor cells pyroptosis under ultrasound stimulation, thereby intensifying the potency of cancer immunotherapy.}, archive = {J_ANGEW}, author = {Sainan Liu and Qi Meng and Zhendong Liu and Jiwei Wang and Jing Li and Xinyu Ma and Yarui Hu and Zhanfeng Wang and Ping'an Ma and Jun Lin}, doi = {10.1002/anie.202421402}, journal = {Angewandte Chemie International Edition}, month = {3}, number = {10}, pages = {e202421402}, shortjournal = {Angew.

Many reports suggested the importance of subsurface carbon in the selective hydrogenation of alkynes over Pd-based catalysts. However, the role of surface carbon has been largely overlooked. We demonstrate that subsurface carbon in Pd is not responsible for the selectivity in acetylene hydrogenation. In contrast, the structure of surface carbonaceous species plays a decisive role in hydrogenation selectivity. Electron microscopy and spectroscopy evidence, along with theoretical modelling, reveal that partial graphitization of surface carbonaceous species results in unique spatial confinement of surface reaction intermediates, thus altering the reaction energy landscape in favour of ethylene desorption as opposed to over-hydrogenation. This mechanism for selectivity control is analogous to enzyme catalysis, where the active centers selectively attract reactants and release products.

  @article{ , abstract = {Mitophagy, particularly in the context of drugs that disrupt mitochondrial membrane potential (MMP), represents a critical focus in pharmacology. However, the discovery and evaluation of MMP-disrupting drugs are often hampered using commercially available marker molecules that target similar or identical zones. These markers can significantly interfere with, obscure, or amplify the functional effects of MMP-targeting drugs, frequently leading to clinical failures. In response to this challenge, we propose a “one-two punch” drug design strategy that integrates both target-zone drug functionality and non-target zone biological reporting within a single small-molecule drug. We have developed a novel proof-of-concept mitophagy self-check drug ( MitoSC ) that exhibits dual-color and dual-localization properties. The functional component of this system is a variable MitoSC that disrupts mitochondrial membrane potential (MMP) homeostasis, thereby inducing mitophagy. Upon activation, this component transforms into a blue-fluorescent monomer ( MitoSC-fun ) specifically within the mitochondrial target zone. Concurrently, the biological reporting component is represented by a red-fluorescent monomer ( MitoSC-rep ) that localizes to lysosomes, the non-target zone. As mitophagy progresses, the fluorescent signals from MitoSC-rep (lysosomes) and MitoSC-fun (mitochondria) converge, enabling real-time monitoring of the mitophagic process. This strategy combines potent drug functionality with robust biological reporting, thereby minimizing interference and eliminating the complexities associated with external detection.

Interestingly, CO reduction products showed an inverse relationship to HER, with KI leading to the highest rate of CO reduction. By pairing our experimental findings with classical molecular dynamics simulations, we propose a mechanism wherein halide anions influence the dynamic interplay between CO reduction and HER by modulating the competition of H* and CO* for active sites on the Cu surface.

For 1-hydroxy, 1-acetyl, 1-carboxy-, and 1-acetamido-adamantane, we demonstrated selective fluorination at the 3-position. We propose two mechanisms for the Co II -catalyzed reaction: either (i) an N-radical, derived from Selectfluor, acted as the C−H oxidant followed by radical rebound with Co III −F; or (ii) a Co IV −(F) 2 species was the C−H oxidant followed by radical rebound with Co III −F. Our combined spectroscopic, kinetic, and chemical trapping evidence suggested that an N-radical was not the active oxidant. We concluded that a Co IV −(F) 2 species was the likely active oxidant and Co III −F was the likely F-atom donor to a carbon centered radical producing a C−F bond.}, archive = {J_ANGEW}, author = {Agnideep Das and Brendan Twamley and Oscar R.

We find that even though one enantiomer reacts faster, as confirmed by reaction monitoring, the other is more tightly bound in DCM (as confirmed by 1 H-saturation transfer difference (STD) measurements).

  @article{ , abstract = {While being important candidate for heterogeneous photocatalyst, conjugated polymer typically exhibits random charge transfers between the alternating donor and acceptor units, which severely limits its catalytic efficiency. Herein, inspired by natural photosystem, the concept of guiding the charge migration to specific reaction sites is employed to significantly boost photocatalytic performance of linear conjugated polymers (LCPs) with pendant functional groups via creating programmed charge-transfer channels from the backbone to its pendant moiety. The pendant benzothiadiazole, as revealed in both in situ X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT) calculations, can act as electron “reservoir” that aggregates electrons at the active sites. Moreover, the presence of charge-transfer channels, evidenced by transient absorption spectroscopy (TAS), accelerates the electron transfer, preventing the recombination of electrons and holes. As a result, in this elaborately-designed architecture, the photogenerated electron can move smoothly towards the reduction sites, facilitating the reduction of O 2 into H 2 O 2 , while remaining holes are directed to oxidation centers, simultaneously oxidizing furfuryl alcohol to furoic acid. The optimized photocatalyst LCP-BT demonstrates a competitive catalytic performance with H 2 O 2 productivity of 868.3 μmol L −1 h −1 (9.8 times higher than conventional random charge-transfer polymer LCP-1) and furfuryl alcohol conversion over 95 % after 6 h.}, archive = {J_ANGEW}, author = {Sizhe Li and Rong Ma and Chuanjun Tu and Weijie Zhang and Run Li and Yan Zhao and Kai A.

While mixed matrix membranes (MMMs) consisting of polymers and metal–organic frameworks (MOFs) offer the potential to address the challenges, they are limited by the low loading of MOFs in the thin film layer. Herein, we propose an inverse synthesis strategy to form polymer-MOF networks by copolymerizing monomers with functionalized UiO-66 nanoparticles.

The membrane with 40 wt % MOF demonstrated a 212 % increment in CO 2 permeance at 25 °C and maintained a selectivity of 20 at 60 °C, which is attributed to the stable diffusivity selectivity of MOFs at high temperature.

  @article{ , abstract = {Charged channels are considered an effective design for achieving efficient monovalent cation transport; however, it remains challenging to establish a direct relationship between charge microenvironments and ionic conductivity within the pores. Herein, we report a series of crystalline covalent organic frameworks (COFs) with identical skeletons but different charge microenvironments and explore their intra-pore charge-driven ion transport performance and mechanism differences. We found that the charged nature determines ion-pair action sites, modes, host-guest interaction, thereby influencing the dissociation efficiency of ion pairs, the hopping ability of cations, and the effective carrier concentration. The order of transport efficiency for Li + , Na + , and H + follows anion > zwitterion > cation > neutrality. Ionic COFs exhibit up to 11-fold higher ionic conductivity than neutral COFs. Notably, the ionic conductivity of anionic COF achieves 2.0 × 10 −4 S cm −1 for Li + at 30 °C and 3.8 × 10 −2 S cm −1 for H + at 160 °C, surpassing most COF-based ionic conductors.

The in situ reconstructed Ga−O−Ir interface sustains high water oxidation rates at oxygen evolution reaction (OER) overpotentials. We found that OER at the Ga−O−Ir interface follows a bi-nuclear adsorbate evolution mechanism with unsaturated IrO x as the active sites, while GaO x atoms play an indirect role in promoting water dissociation to form OH* and transferring OH* to Ir sites. This breaks the scaling relationship of the adsorption energies between OH* and OOH*, significantly lowering the energy barrier of the rate-limiting step and greatly increasing reactivity.

In developing more sustainable electro-organic synthesis, we've harnessed the aqueous micelles as solvents and electrolyte-like structures when deformed under an electric field.

This mild electrosynthetic method produces monofluorinated unprotected indole scaffolds. Our approach minimizes waste and enhances atom economy, reducing reliance on expensive and hazardous solvents and electrolytes. The surfactant's potential for recycling was verified for two cycles. Cyclic voltammetry analysis has corroborated that PS-750-M micelles in water establish a more efficient platform for hydrodefluorination.

Here we report Ni-catalyzed reductive hydrolysis of nitriles to alcohols in the presence of molecular hydrogen. This conversion likely occurs in a domino reaction sequence that first involves the hydrogenation of nitrile to primary imine, then the hydrolysis of imine, and subsequent deamination to the aldehyde, which is finally hydrogenated to the desired alcohol. Crucial for this reductive hydrolysis process is the commercially available triphos-ligated Ni-complex that enables highly efficient and selective transformation of aromatic, heterocyclic, and aliphatic nitriles including fatty nitriles to prepare functionalized primary alcohols. Further, the synthetic applicability of this Ni-based protocol is presented for the selective conversion of nitrile to alcoholic group in structurally diverse and complex drug molecules as well as agrochemicals.

  @article{ , abstract = {In the fight against bacterial infections, particularly those caused by multi-resistant pathogens known as “superbugs”, the need for new antibacterials is undoubted in scientific communities and is by now also widely perceived by the general population. However, the antibacterial research landscape has changed considerably over the past years. With few exceptions, the majority of big pharma companies has left the field and thus, the decline in R&D on antibacterials severely impacts the drug pipeline. In recent years, antibacterial research has increasingly relied on smaller companies or academic research institutions, which mostly have only limited financial resources, to carry a drug discovery and development process from the beginning and through to the beginning of clinical phases. This review formulates the requirements for an antibacterial in regard of targeted pathogens, resistance mechanisms and drug discovery. Strategies are shown for the discovery of new antibacterial structures originating from natural sources, by chemical synthesis and more recently from artificial intelligence approaches. This is complemented by principles for the computer-aided design of antibacterials and the refinement of a lead structure. The second part of the article comprises a compilation of antibacterial molecules classified according to bacterial target structures, e.g. cell wall synthesis, protein synthesis, as well as more recently emerging target classes, e.g. fatty acid synthesis, proteases and membrane proteins.

  @article{ , abstract = {The catalytic action of enzymes in a cascade trapped within a mesoporous electrode material is simultaneously energized, controlled and observed through the efficient, reversible electrochemical NAD(P)(H) recycling catalyzed by one of the enzymes. In their nanoconfined state, nicotinamide cofactors are tightly channeled current carriers, mediating multi-step reactions in either direction (oxidation or reduction) with a rapid response time. By incorporating a hydrogen-borrowing enzyme pair, the internal action of which opposes the external voltage bias driving oxidation or reduction, a reduction process can be performed under overall oxidizing conditions, and vice versa. The power of the method to control and resolve complex metabolic pathways is demonstrated using a non-linear, three-enzyme cascade extended by incorporating a fourth enzyme, urease. The latter generates in situ ammonia, which is enzymatically consumed in a reductive process, but the immediate current response to each addition of urea is observed, unusually, by applying an oxidizing potential. A practical consequence is that enzyme-catalyzed electrochemical reduction reactions requiring anaerobic conditions (to avoid O 2 interference) can readily be studied under ambient aerobic conditions. The results illustrate how a complex enzyme cascade confined within a porous electrode and connected to an electrical power source manifests characteristics associated with electronic circuits.}, archive = {J_ANGEW}, author = {Ryan A.

Molecular imaging techniques are valuable tools to overcome the current poor understanding of MAGL's distribution and role in patho- and physiological processes within ECS signaling. Herein, we report the design, synthesis, and validation of highly selective versatile fluorescent and click-chemistry probes for MAGL. Structure-based design combined with a reverse-design approach allowed the development of a structural unit that selectively and effectively recognizes MAGL while offering a versatile platform to attach different fluorophores and further reporter units. In this way, labeled probes with sub-nanomolar potency carrying diverse fluorescent dyes were obtained. Probe affinity and selectivity remained invariant to changes in the fluorophore subunit, showing the remarkable robustness of this platform in delivering tailor-made probes. Highly consistent inhibition across species supports pharmacological model translatability.

To address this, an engineered nanopore was designed, capable of discriminating single hydroxyl group on proline, to achieve the identification of proline hydroxylation on individual native peptides directly in mixture. By modeling the interaction between hydroxylated proline and its specific recognition protein, we introduced a hydrophobic region in aerolysin lumen with A224Y/T274W mutations to enhance the sensitivity for proline residue.

Whereas, Pd electrocatalyst becomes nearly deactivated within 6 h of reaction under conventional potentiostatic strategy. Experimental and theoretical calculation results reveal that the generated electrophilic OH* from H 2 O/OH − oxidation on Pd (denoted as Pd−OH*) acts as main active species for GLY oxidation.

Separator modification is an effective strategy to address the challenges of LMBs. To tackle the issues, a donor–acceptor polymer (ArMT) consisting of benzene rings and triazine was successfully synthesized and modified onto commercial polypropylene (ArMT@PP) as separators for LMBs.

In this study, we synthesized chlorine-containing RuO 2 (RuO 2 -Cl) and pure RuO 2 catalysts with similar morphology and crystallinity. RuO 2 -Cl demonstrated superior stability, three times greater than that of pure RuO 2 , and a lower overpotential of 176 mV at 10 mA cm −2 . Furthermore, the RuO 2 -Cl catalysts that were in situ synthesized on a platinum-coated titanium felt could maintain high performance for up to 1200 hours at 100 mA cm −2 . Computational and experimental analyses show that chloride stabilizes RuO 2 by substituting the bridging oxygen atoms, which subsequently inhibits lattice oxygen evolution and Ru demetallation.

  @article{ , abstract = {Photoiniferter (PI) is a promising polymerization methodology, often used to overcome restrictions posed by thermal reversible addition-fragmentation chain-transfer (RAFT) polymerization. However, in the overwhelming majority of reports, high energy UV irradiation is required to effectively trigger photolysis of RAFT agents and facilitate the polymerization, significantly limiting its potential, scope, and applicability. Although visible light PI has emerged as a highly attractive alternative, most current approaches are limited to the synthesis of lower molecular weight polymers (i.e. 10,000 g/mol), and typically suffer from prolonged reaction times, extended induction periods, and higher dispersities when high activity CTAs (photoiniferters), such as trithiocarbonates, are employed. Herein, an acid-enhanced PI polymerization is introduced that efficiently operates under visible light irradiation. The presence of small amounts of biocompatible citric acid fully eliminates the lengthy induction period (21 hours) by enhancing photolysis, rapidly consuming the CTA, and accelerating the reaction rate, yielding polymers with narrow molar mass distributions ( Ð ~1.1), near-quantitative conversions (>97 %), and high end-group fidelity in just two hours. A particularly noteworthy aspect of this work is the possibility to target very high degrees of polymerization (i.e. DP=3,000) within short timescales (i.e. less than five hours) without compromising the control over the dispersity ( Ð ~1.1). The versatility of the technique is further demonstrated through the synthesis of well-defined diblock copolymers and its compatibility to various polymer classes (i.e. acrylamides, acrylates, methacrylates), thus establishing visible-light PI as a robust tool for polymer synthesis.}, archive = {J_ANGEW}, author = {Maria-Nefeli Antonopoulou and Nghia P.

Herein, we report a chemical-mechanical driven in situ interface reconstruction strategy to solve such interface contact issues. The in situ interface reconstruction is firstly triggered by methylammonium chloride (MACl) surface treatment to chemically activate the film and then mechanically laminate the carbon electrode onto the softened perovskite film under heating. The perovskite film undergoes in situ regrowth and the carbon film starts to cure simultaneously, dynamically reconstructing the perovskite/carbon electrode interface. A tighter and conformal contact is achieved, greatly facilitating the carrier transport and extract. Ultimately, a champion PCE of 20.31 % is achieved with enhanced stability.

  @article{ , abstract = {Quantum dots (QDs) are semiconductor nanocrystals whose optical properties can be tuned by altering their size. By combining QDs with dyes we can make hybrid QD-dye systems exhibiting energy transfer (ET) between QDs and dyes, which is important in sensing and lighting applications. In conventional QDs that need a shell to passivate surface defects, ET usually proceeds through Förster resonance energy transfer (FRET) that requires significant spectral overlap between QD emission and dye absorbance, as well as large oscillator strengths of those transitions. This considerably limits the choice of dyes. In contrast, perovskite QDs do not require passivating shells for bright emission, which makes ET mechanisms beyond FRET accessible. This work explores the design of a CsPbBr 3 QD-dye system to achieve efficient ET from CsPbBr 3 QDs to dyes with dimethyl iminium binding groups where the close binding of dyes to CsPbBr 3 surface facilitates spatial wavefunction overlap. Using steady-state and time-resolved photoluminescence experiments, we demonstrate that efficient ET from CsPbBr 3 to dyes with minimal spectral overlap proceeds via the Dexter exchange-type mechanism, which overcomes the conventional restriction of spectral overlap that severely limits the tunability of these systems.

Dynamic covalent cross-linking of polymers has emerged as a viable solution that can combine the structural integrity of thermosetting materials with the (re−)processability of thermoplastics. Thioether linkages between polymer chains are quite common, and their use dates back to the vulcanization of rubbers. While it is known that thioether bonds can be triggered to exchange through transalkylation reactions, this process is usually slow, as thioether moieties not only have to be activated by an alkylating agent, but the activated thioether also has to associate with a second thioether moiety in a classical S N 2-type process. Here, we present the rational design of dynamic polymer networks based on simple dithiol-based monomers and a fatty acid derived triene. Two neighboring thioethers can undergo a much faster bond exchange reaction, and we found that the exchange dynamics can be further tuned over almost three orders of magnitude by tailoring the distance between two thioether functionalities.

These iCOFs are characterized by numerous hydrophilic sites and high water stability, enabling efficient water vapor adsorption even at relatively low humidity levels. Through the use of various hygroscopic salt cations and precise control of ion concentration within the pores, the water state within the iCOFs pores can be effectively managed. Among the iCOFs, TB-COF-Li stands out with an impressive adsorption capacity of 0.24 g g −1 from 0 to 22 % RH. Notably, due to its ionic porous structure, TB-COF-Li exhibits a significantly lower enthalpy of evaporation, measured at 967.04 J g −1 , compared to bulk water with an enthalpy of 2387.40 J g −1 . Moreover, under simulated conditions of 1.5 solar intensity at 60 °C, the majority of the adsorbed water can be rapidly desorbed without the need for additional energy input. This efficient desorption process contributes to a high water collection rate of 0.092 g g −1 h −1 in the final atmospheric water harvesting device.

  @article{ , abstract = {Currently, direct electrolysis of seawater for green hydrogen production is primarily focused on neutral and alkaline systems. However, the precipitation of calcium and magnesium ions restricts the advancement of this technology. An acidic system can effectively address this issue. Given that Ru/Ir-based catalysts with high oxygen evolution reaction (OER) activity also exhibit high chlorine evolution reaction (CER) activity, acid seawater splitting requires anodes with higher selectivity and stability compared to the other two systems. In this study, we propose a non-precious Ru 0.1 Mn 0.9 O x as the active anode for direct acid seawater electrolysis, which exhibits a high OER selectivity and remarkable stability for more than 1200 hours. Different from the Cl − -free system, *Cl occupied on Ru sites could shift the OER active center to Mn on Ru 0.1 Mn 0.9 O x , which prevents the lattice oxygen consumed on Ru and hinders the metal site dissolution. As the CER-insensitive catalytic center, Mn activated by the introduction of Ru can adsorb a substantial amount of *OH, creating an OER-favored local environment that inhibits CER. We introduce Cl − -assisted transfer of OER active sites to CER-insensitive Mn as a fundamental strategy for achieving highly selective and durable oxygen evolution in acidic seawater.}, archive = {J_ANGEW}, author = {Jun Xu and Chun-Chuan Kao and Haifeng Shen and Hao Liu and Yao Zheng and Shi-Zhang Qiao}, doi = {10.1002/anie.202420615}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {9}, pages = {e202420615}, shortjournal = {Angew.

However, G4 s tend to adopt different conformations depending on the exact environmental conditions, and often only one displays the specifically desired biological activity. Their less intensively studied counterparts, the elusive tetraplexed intercalated-motifs (IMs) are typically unstable at neutral pH, hampering the investigation of their potential involvement in a biological context. We herein report on a photochemical method for “stapling” such tetraplexed-structures, to increase their stability, lock their topology and enhance their enzymatic resistance, while maintaining biological activity.

In this study, we developed a series of phenothiazine-based Ar-SAMs to investigate how different aromatic linkers could affect molecular stacking, the regulation of substrate work function, and charge carrier dynamics. When served as hole-selective layers (HSLs) in PSCs and monolithic perovskite/silicon tandem solar cells (P/S-TSCs), we found that the Ar-SAM with naphthalene linker along the 2,6-position axis ( β -Nap) could form dense and highly ordered HSLs, enhancing interfacial interactions and favoring optimal energy level alignment with the perovskite films. Using this strategy, the optimized wide-band gap PSCs achieved an impressive power conversion efficiency (PCE) of 21.86 % with negligible hysteresis, utilizing a 1.68 eV perovskite.

A porphyrin precursor equipped with carbonitrile moieties in a trans arrangement was prepared by solution synthesis and deposited on Au(111)/mica. Depending on the specific growth protocol, surface-promoted reactions led to the transformation of the precursor into non-magnetic Au-CN coordinated porphyrin monomers, covalent porphyrin dimers, and one-dimensional porphyrin polymers (based on porphyrin monomers or covalent porphyrin dimers), as revealed by scanning probe microscopy studies combined with theoretical calculations. Interestingly, the scanning tunneling microscopy tip could convert such closed-shell porphyrin units into open-shell species by the removal of some peripheral hydrogen atoms.

While the position of the fluorescence emission remains constant—due to the stability provided by the hydrogen bonding network of the peptide backbone—the intensity of the fluorescence exhibits a direct correlation with the degree of self-assembly.

  @article{ , abstract = {Nitrogen heterocyclic carbenes (NHCs) are emerging as effective substitutes for conventional thiol ligands in surface functionalization of nanoparticles (NPs), offering exceptional stability to NPs under harsh conditions. However, the highly reactive feature of NHCs limits their use in introducing chemically active groups onto the NP surface. Herein, we develop a general yet robust strategy for the efficient surface functionalization of NPs with copolymer ligands bearing various functional groups. The polymer ligands consist of a multiple NHCs block, utilized for surface binding on NPs, alongside a poly(reactive ester) block intended for incorporating functional groups. The multiple NHCs block enables NPs with excellent colloidal stability across a broader range of pH values (0–14), temperature variations (–78 °C-100 °C), and electrolyte concentrations (0–1000 mM). Through the in situ ammonolysis of the poly(reactive ester) block, various active functional groups can be individually or together introduced on the NP surface. We further demonstrate the chemical reactivity of these functionalized NPs, including addition polymerization, Diels–Alder and Schiff base reactions. This method is applicable to various types of NPs, including metal NPs, metal oxide NPs, and even upconversion NPs, thereby paving new pathways for the design and creation of nanoparticle-based functional materials.}, archive = {J_ANGEW}, author = {Jing Tao and Di Zheng and Yutian Tang and Huibin He and Yan Zhang and Yanqiong Yang and Liwei Dai and Huaining Zha and Yutao Sang and Zhihong Nie}, doi = {10.1002/anie.202419640}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {9}, pages = {e202419640}, shortjournal = {Angew.

  @article{ , abstract = {Iron-nitrogen-carbon (Fe−N−C) single-atom catalyst is the most promising alternative to platinum catalyst for proton-exchange membrane fuel cells (PEMFCs), however its high performance cannot be maintained for a long enough time in device operation. The construction of a new Fe coordination environment that is completely different from the square-planar Fe−N 4 configuration in classic Fe−N−C catalyst is expected to break the current stability limits of Pt-free catalysts, which however remains unexplored. Here, we report, for the first time, the conversion of Fe−N−C catalyst to a new FeN x Se y cluster catalyst, where the active Fe sites are three-dimensionally (3D) co-coordinated by N and Se atoms. Due to this unique Fe coordination configuration, the FeN x Se y catalyst exhibits much better 4e − ORR activity and selectivity than the state-of-the-art Fe−N−C catalyst. Specifically, the yields of hydrogen peroxide (H 2 O 2 ) and ⋅OH radicals on the FeN x Se y catalyst are only one-quarter and one-third of that on the Fe−N−C counterpart, respectively. Therefore, the FeN x Se y catalyst exhibits outstanding cyclic stability, losing only 10 mV in half-wave potential E 1/2 after 10,000 potential cycles, much smaller than that of the Fe−N−C catalyst (56 mV), representing the most stable Pt-free catalysts ever reported for PEMFCs. More significantly, the 3D co-coordination structure effectively inhibits the Fe demetallization of the FeN x Se y catalyst in the presence of H 2 O 2 . As a result, the FeN x Se y based PEMFC shows excellent durability, with the current density attenuation significantly lower than that of the Fe−N−C based device after accelerated durability testing.

The G 4 .Cu + self-assembled in water through π-π stacking, metallophilic and hydrophobic interactions, forming thermally robust SPs.

Demonstrating such systems would be both fundamentally intriguing and practically relevant, especially if the resulting particles self-assemble into complex structures beyond the capabilities of molecules or droplets. Here, we show that autocatalytic nucleation occurs with silver nanoparticles, which subsequently self-assemble into chains through spatially restricted attachment. In dispersions containing “hedgehog” particles, these reactions produce complex colloids with hierarchical spike organization. On solid surfaces, autocatalytic nucleation of nanoparticles yields conformal networks with hierarchical organization, including nanoparticle “colonies.” We analyzed the complexity of both types of solid-stabilized particle assemblies via graph theory (GT). The complexity index of idealized spiky colloids is comparable to that of complex algal skeletons. The GT analysis of the percolating nanoparticle networks revealed their similarities to the bacterial, but not fungal, biofilms. We conclude that coupling autocatalytic nucleation with self-assembly enables the generation of complex, biosimilar particles and films. This work establishes mathematical and structural parallels between biotic and abiotic matter, integrating self-organization, autocatalytic nucleation, and theoretical description of complex systems. Utilization of quantitative descriptors of connectivity patterns opens possibility to GT-based biomimetic engineering of conductive coatings and other complex nanostructures.}, archive = {J_ANGEW}, author = {Connor N.

The synergism of LND and nanozyme affords a high microglial Aβ clearance efficacy without triggering mitochondrial dysfunction. In vivo experiments ascertain that LND@HMPB-T7 could synergistically promote phagocytic clearance of Aβ, relieve neuroinflammation and ameliorate cognitive function in AD mice.

  @article{ , abstract = {Li-TFSI/ t -BP is the most widely utilized p-dopant for hole-transporting materials (HTMs) in state-of-the-art perovskite solar cells (PSCs). However, its nonuniformity of doping, along with the hygroscopicity and migration of dopants, results in the devices exhibiting limited stability and performance. This study reports on the utilization of a spherical anion derived from the p-dopant, regulated by its radius and shape, as an alternative to the linear TFSI − anion. The theoretical and experimental results reveal that the spherical anion significantly increases the doping effect of HTMs due to an enhanced electron transfer from larger dipole moments. The enhanced transfer leads to a shift in the Pb-6p defect orbitals, resulting in shallower trap states. Moreover, compared to the linear structure of the TFSI − anion, the anion of sodium tetrakis[3,5-bis(trifluoro methyl)phenyl]borate (Na-TFPB) with a larger van der Waals radius and spherical shape offers increased hydrophobicity and migration barriers, which can protect the perovskite crystal and facilitate stable p-doping of HTMs. The use of Na-TFPB results in enhanced thermal and ambient stability of PSCs.

Herein, the strategy of enhancing cage-confinement effect to control molecular motion has been probed for the first time to exploit new high- T c ferroelectrics of 2D hybrid perovskites. By fine-tailoring of the confined cations inside the perovskite cavities, we have successfully obtained new homologous ferroelectrics of (BA) 2 (MA) 2 Pb 3 Cl 10 ( 1 ; BA = n -butylamine, MA=methylamine) and (BA) 2 (EA) 2 Pb 3 Cl 10 ( 2 ; EA=ethylamine).

  @article{ , abstract = {Clusteroluminogens (CLgens) represent an innovative class of nonconjugated luminophores that address the limitations of conventional π-conjugated molecules. Different from the through-bond conjugation mechanism in π-conjugated luminophores, through-space conjugation (TSC) plays dominant roles in CLgens. However, precisely controlling TSC to customize the optical properties of CLgens remains a significant challenge. This work proposes a novel strategy of high pressure to engineer TSC within tetraphenylalkanes (TPAs)-based CLgens at molecular level. High-pressure exploration enables accurate manipulation of clusteroluminescence and elucidates the intrinsic structure–property relationships involved. Upon initial compression, the predominant molecular distortions marked by increased interfacial angles between benzene rings diminish TSC, resulting in anomalous hypochromatic shift in emission. Subsequently, considerable structural contraction enhances TSC and suppresses molecular motion, resulting in a pronouncedly enhanced and bathochromic-shifted emission. Notably, a series of TPAs-based CLgens exhibit intense white-light emission upon pressure release, attributed to irreversible structural distortion and destruction. This study not only advances the understanding of CLgens, but also underscores the crucial structural factors for effective TSC control, paving the way for establishing new photophysical theories for aggregate science.}, archive = {J_ANGEW}, author = {Yayun Wang and Zuping Xiong and Yanan Wang and Aisen Li and Yuanyuan Fang and Lei Li and Kai Wang and Qian Li and Haoke Zhang}, doi = {10.1002/anie.202420502}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {8}, pages = {e202420502}, shortjournal = {Angew.

Manipulating the in situ reconstruction of Ir-based catalysts with favorable kinetics is highly desirable but remains elusive.

Under working conditions, the strong heteroatom-bonded structure triggers rational surface-confined reconstruction to form self-stabilizing amorphous (oxy)hydroxides on the model Ir−Mn intermetallic (IMC). Combined in situ/ex situ characterizations and theoretical analysis demonstrate that the induced strong covalent Ir−O−Mn units in the catalytic layer weaken the formation barrier of OOH* and promote the preferential dynamic replenishment/conversion pathway of H 2 O molecules to suppress the uncontrollable participation of lattice oxygen (about 2.6 times lower than that of pure Ir).

Herein we report the first highly efficient ruthenium-catalyzed hydroboration of allenes featuring exclusive α-regioselectivity, providing access to sterically hindered allyl boranes that are limitedly accessible by conventional methods.

Our findings reveal that the π-electrons located in the conjugated system do not directly present strong passivation for defects, but enhance the electron cloud density of the carbonyl group augmenting its interaction with defect sites; thereby, with the extended conjugation plane of the three molecules, their defect passivation ability is gradually improved.

Based on the transformation of N -(2-alkynylphenyl) sulfoximines to 3 H -indol-3-ones, it is demonstrated that the sulfoximine functionality is capable of selectively transferring first its nitrogen moiety to the alkyne, forming the α-imino gold carbene, which is then oxidised by the released sulfoxide moiety in a second step via a pseudo-intramolecular mechanism—a distinctive feature that differentiates this work mechanistically from earlier studies. A combination of extensive experimental and theoretical studies provides evidence for this mechanistic rationale. As no external reagents for the 1,2-difunctionalisation of the alkyne unit are required, a wide variety of functional groups are tolerated in the transformation, affording the desired 3 H -indol-3-ones in mostly good yields.

Herein, we developed a strategy that unitizes electrode potential to control the interactions between active sites and intermediates over oxygen vacancy-modified TiO 2 (V O −TiO 2−x ) to enhance NORR performance. By combining state-of-the-art constant inner potential (CIP) DFT calculations with in situ (spectro)electrochemical measurements, we investigated how the electrode potential influences these interactions in NORR.

Comprehensive experiments and theoretical calculations revealed that the distorted CoP 4 configuration caused a strong charge redistribution between the Co atoms and adjacent C atoms, minimizing their electronegativity difference.

Herein, we exploit an excitation-dependent CLCs ( ExD-CLCs ) material by establishing dynamically photoresponsive dichroic competition between two achiral dyes: a negative dichroic dye ( SP-COOH ) and a positive dichroic dye (Nile Red, NR ) within a CLCs medium. The ExD-CLCs exhibits a negative circularly polarized luminescence (CPL) signal ( g lum =−0.16) at 625 nm when excited at 365 nm. Remarkably, under excitation at 430 nm, the CPL signal is inverted, and the g lum value increases to +0.26. Notably, the helical superstructure and handedness of the ExD-CLCs remain unchanged during this reversal process. The CPL signal reversal is driven by the dichroic competition between the SP-COOH dimer, which displays strong negative dichroism in its open-ring isomer form and silent negative dichroism in its closed-ring isomer form, and the NR dye, which exhibits static positive dichroism.

  @article{ , abstract = {Protein kinases are important drug targets, yet specific inhibitors have been developed for only a fraction of the more than 500 human kinases. A major challenge in designing inhibitors for highly related kinases is selectivity. Unlike their non-covalent counterparts, covalent inhibitors offer the advantage of selectively targeting structurally similar kinases by modifying specific protein side chains, particularly non-conserved cysteines. Previously, covalent fragment screens yielded potent and selective inhibitors for individual kinases such as ERK1/2 but have not been applied to the broader kinome. Furthermore, many of the accessible cysteine positions have not been addressed so far. Here, we outline a generalizable approach to sample ATP-site cysteines with fragment-like covalent inhibitors. We present the development of a kinase-focused covalent fragment library and its systematic screening against a curated selection of 47 kinases, with 60 active site-proximal cysteines using LC/MS and differential scanning fluorimetry (DSF) assays, followed by hit validation through various complementary techniques. Our findings expand the repertoire of targetable cysteines within protein kinases, provide insight into unique binding modes identified from crystal structures and deliver isoform-specific hits with promising profiles as starting points for the development of highly potent and selective covalent inhibitors.}, archive = {J_ANGEW}, author = {Guiqun Wang and Nico J.

The critical roles of the two salt additives, lithium iodide and zinc acetate, in orchestrating the two cycles were also elucidated.

We identify an SP-containing compound, SP-PEG 8 -SP, that forms coacervates ( SP-C ) in the aqueous solution.

The as-designed Se−C demonstrates nearly 100 % 4-electron selectivity, evidenced by 0.039 % of H 2 O 2 yield at 0.5 V versus reversible hydrogen electrode, outperforming commercial platinum (Pt) by 65 times. In situ X-ray absorption spectroscopy and theoretical calculations attribute this exceptional selectivity to the enzyme-like behaviors of the Se site to steal an O atom from peroxide intermediates. The second achievement is the significantly increased consecutive 2+2 electron selectivity. Benefiting from the enzyme-like H 2 O 2 reduction activity with a higher onset potential of 0.915 V compared to Pt at 0.875 V, the Se−C as a secondary catalytic site reduced the H 2 O 2 yields of the Co−N−C, Fe−N−C, and N−C catalysts by 96 %, 67 %, and 98 %, respectively, via a consecutive 2+2 electron pathway.

  @article{ , abstract = {Ammonia electrosynthesis through the lithium-mediated approach has recently reached promising results towards high activity and selectivity in aprotic media, reaching high Faradaic efficiency (FE) values and NH 3 production rates. To fasten the comprehension and optimization of the complex lithium-mediated nitrogen reduction system, for the first time a multivariate approach is proposed as a powerful tool to reduce the number of experiments in comparison with the classical one-factor-at-a-time approach. Doehlert design and surface response methodology are employed to optimize the electrolyte composition for a batch autoclaved cell. The method is validated with the common LiBF 4 salt, and the correlations between the FE and the amount of lithium salt and ethanol as proton donor are elucidated, also discussing their impact on the solid electrolyte interphase (SEI) layer. Moreover, a new fluorinated salt is proposed (i.e., lithium difluoro(oxalate) borate (LiFOB)), taking inspiration from lithium batteries. This salt is chosen to tailor the SEI layer, with the aim of obtaining a bifunctional interfacial layer, both stable and permeable to N 2 , the latter being an essential characteristic for batch systems. The SEI layer composition is confirmed strategic and its tailoring with LiFOB boosts FE values.}, archive = {J_ANGEW}, author = {Anna Mangini and Jon Bjarke Valbæk Mygind and Sara Garcia Ballesteros and Alessandro Pedico and Marco Armandi and Ib Chorkendorff and Federico Bella}, doi = {10.1002/anie.202416027}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {8}, pages = {e202416027}, shortjournal = {Angew.

  @article{ , abstract = {Dynamic molecules with tunable chemical and physical properties in response to external stimuli hold great potential for applications in various fields such as information storage, smart molecular machines, and biomimetics. Among them, supramolecular springs and spin-crossover (SCO) complexes can both undergo visible macroscopic changes under heat or light stimulation. In this study, we synthesized a unique trinuclear Fe(II)-SCO complex, [( R −L)Fe II {Au(CN) 2 } 2 ] ( R 1 ), using a chiral chelating ligand decorated with rotatable benzyl rings. The [FeAu 2 ] trinuclear molecules form a 2 1 -helical supramolecular chain via elastic Au Au contacts. Interestingly, the synergy between the multiple dynamic factors (SCO event, rotation of the rings, and flexibility in Au Au distance) endows the complex with multiple switchings in both magnetism and structure, as well as the most intriguing characteristic of giant and anisotropic “breathing” feature in thermal expansion within two distinct temperature regimes. Specifically, complex R 1 undergoes two hysteretic magnetic transitions: a non-spin transition between 360 and 380 K and an unsymmetric SCO transition in the region of 160–280 K, associated with a symmetry-breaking event between the non-polar and polar space groups (P2 1 2 1 2 1 ↔P2 1 ). Both transitions are triggered/accompanied by the rotation (inward vs . outward) of the benzyl rings. Correspondingly, reversible spring-like motions of the helical chains with the helical pitches varying from 11.345 140 K to 12.509 280 K then back to 11.630 380 K Å are observed in the two distinct temperature regimes.

Here, we have developed mirror-image random nonstandard peptides integrated discovery (MI-RaPID) technology to discover innate protease-resistant macrocyclic peptides that specifically bind to and inhibit human MMP7. One identified macrocyclic peptide against D -MMP7, termed D20 , was synthesized in its mirror-image form, D’20 , consisting of 12 D -amino acids, one cyclic β-amino acid, and a thioether bond. Notably, it potently inhibited MMP7 with an IC 50 value of 90 nM, and showed excellent selectivity over other MMPs with similar substrate specificity. Moreover, D’20 inhibited the migration of pancreatic cell line CFPAC-1, but had no effect on the cell proliferation and viability. D’20 exhibited excellent stability in human serum, as well as in simulated gastric and intestinal fluids.

The vast majority of GETSs are comprised of a FRET pair flanking an elastic “spring-like” domain that gradually extends in response to force. Because of ensemble averaging, the FRET signal generated by such analog sensors conceals forces that deviate from the average, and hence it is unknown if a subset of proteins experience greater magnitudes of force. We address this problem by developing digital GETSs comprised of coiled-coils (CCs) with tunable mechanical thresholds. We validate the mechanical response of CC digital probes using thermodynamic stability prediction, AlphaFold2 modeling, steered molecular dynamics simulations, and single-molecule force spectroscopy. Live cell measurements using optimized CC tension sensors that are inserted into vinculin demonstrate that 13 % of this mechanosensor experiences forces >9.9 pN within focal adhesions. This reveals greater magnitudes of vinculin force than had previously been reported and demonstrates that CC tension sensors enable more facile and precise tension measurements in living systems.}, archive = {J_ANGEW}, author = {Shuhong Liu and Jinchan Liu and Alexander Foote and Hiroaki Ogasawara and Sarah Al Abdullatif and Victor S.

Although a variety of polymer-based gas-releasing carriers have been designed, almost all the systems are limited to spherical structures. Here we explore the role of polymer self-assembled morphologies, especially toward those non-spherical nanostructures, on the H 2 S release capacity. A kind of tubular polymersomes (i.e. tubesomes), formed by the membrane stretching of polythionoester-containing block copolymer vesicles, exhibit enhanced cysteine-responsive H 2 S-releasing behavior in contrast to their spherical counterparts. Moreover, we found that the amount and rate of H 2 S release from diverse polymersomes is relied on the extent of membrane elongation, which allows us to regulate the gas releasing kinetics through tailoring the membrane geometries. More importantly, it is demonstrated that the tubesomes as polymer-type H 2 S donors have better anticancer performance than those spherical polymersomes.

  @article{ , abstract = {A pyrrole-fused analogue of warped nanographene, designated as deca-nitrogen doped ′ WNG ′ ( azaWNG ), was synthesized through the annular fusion of decapyrroylcorannulene. The resulting azaWNG exhibited extremely limited solubility in common organic solvents and was characterized solely by mass spectrometry. Theoretical calculations revealed that azaWNG has a sunflower-like molecular structure with electron-deficient corannulene as the core and electron-rich pyrrole as the petals, demonstrating a significantly narrower energy gap compared to all-carbon WNG . To improve its solubility and facilitate precise structural characterization, iodine monochloride was utilized for edge-perchlorination of azaWNG , enabling successful separation and purification of chlorinated azaWNG in solution phase. X-ray crystallography analysis unequivocally confirmed that edge-perchlorinated azaWNG contains 5 heptagons and 11 pentagons embedded within the warped π skeleton.

Among them, Zr-α employs a simple cubic arrangement and is a common centrosymmetric superstructure, which consists of a pair of equimolar metallo-tetrahedra enantiomers in its unit cell. While Zr-β results in conglomerates with spontaneous resolution without using any resolving agents, giving rise to two enantiopure entities separately (Zr-β- P , Zr-β- M ). More importantly, Zr-γ breaks the inversion center of symmetry and crystallizes into a racemic yet non-centrosymmetric superstructure with face-centered cubic packing mode. Based on the non-centrosymmetric nature, the hierarchical superstructure Zr-γ displayed good second harmonic generation activities. This work presents a successful instance wherein the reaction solvent induces the modulation of intermolecular packing mode to afford non-centrosymmetric solid materials, which can greatly promote the development of noncentrosymmetric solid (NCS) materials.}, archive = {J_ANGEW}, author = {Ermeng Han and Yu-Qing Li and Tun Wu and Qixia Bai and Zhe Zhang and Jie Yuan and Wei Liu and Die Liu and Yiming Li and Pingshan Wang}, doi = {10.1002/anie.202420223}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {7}, pages = {e202420223}, shortjournal = {Angew.

The H 2 O 2 production rate originates from the synergistic effect between an ultrasonication-induced polarized electric field and the spatially separated multiple charge transfer channels, which significantly promote the utilization of photogenerated electrons by directional transfer from bicarbazole groups to the ethenyl group-modified benzene rings.

Despite extensive studies, the reaction of SCBs with simple alkenes has only one precedent. Moreover, most reported reactions of SCBs use late transition metals (Pd, Ni, Rh) as catalysts. By contrast, there are no reports of using early transition metals. Herein, we report the first example, to our knowledge, of early-transition-metal-catalyzed reactions of SCBs using earth's second abundant titanium as a catalyst. Notably, orthogonal selectivity was observed. Selective activation of the relatively inert C(sp 3 )−Si bond was achieved in the case of benzosilacyclobutenes, a selectivity that has rarely been achieved using other metals. Even for silacyclobutanes with C(sp 3 )−Si bonds only, our titanium system also shows complementary selectivity towards late transition metals to give distinct products. Thus, structurally varied SCBs and alkenes were reacted in our system to afford structurally diverse silicon-containing products that are otherwise difficult to obtain using other transition metals.}, archive = {J_ANGEW}, author = {Yaqiong Wang and Jiong Zhang and Fang Wang and Lipeng Wu}, doi = {10.1002/anie.202420092}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {7}, pages = {e202420092}, shortjournal = {Angew.

However, current ultra-narrow bandgap materials applied in OPVs, primarily based on electron-rich cores, exhibit defects of high-lying energy levels and inferior performance. We herein proposed a novel strategy by designing the benzothiazole-fused cyanoindone (BTC) unit with ultra-strong electron-withdrawing ability as the terminal to synthesize the acceptor BTC-2. The BTC unit imparts red-shifted absorption up to 1000 nm to BTC-2, attributed to enhanced intramolecular charge transfer and the quinoid resonance effect. Additionally, BTC-2 features deep-lying energy levels with the highest occupied molecular orbital level of −5.81 eV, due to the ultra-strong electron-withdrawing ability of BTC. Furthermore, BTC-2 exhibits long-range ordering in both molecular packing and macroscopic blend morphology, resulting from shoulder-to-shoulder packing of two BTC units, leading to an ultra-long exciton lifetime over 1.1 ns. These superiorities facilitated a 17.17 % efficiency in the binary OPV device with an extremely high photocurrent of 30.34 mA cm −2 , representing the best performance for ultra-narrow bandgap electron acceptors, and a record light utilization efficiency of 4.88 % in binary semi-transparent systems.

Regularly arranging these heterogeneous pores can significantly optimize the combined effect of the introduced components. Porous Organic Cages (POCs), an emerging subclass of porous materials composed of discrete molecules, assemble to form interconnected pores and exhibit permanent porosity in the solid state. A unique feature of POCs is their modularity, enabling a “mix and match” approach to create co-crystal structures driven by the intermolecular interactions. Herein, we adopted the cocrystallization strategy for fabricating gas separation membranes. We prepared membranes from a series of [4+6] imine cage pairs, which vary in cavity sizes and include cages with fluorescence properties. By optimizing the cocrystalization conditions, we successfully fabricated continuous, defect-free gas membranes, benefiting from chiral recognition interactions. By introducing regularly alternating small and large pores, we addressed challenges such as the trade-off between permeability and selectivity in gas separation membrane.

Instead, they work as external forces applied directly onto the crystals themselves, ‘‘squeezing” the materials to close the voids through supramolecular interactions between EA and macrocycles on the crystal surface and release the guest molecules.

We conjugate the peptide with shape-persistent polyhedral oligomeric silsesquioxane (POSS), which acts as a hydrophilic head and senses the solvent environment. The POSS-peptide amphiphiles display two distinct self-assembly pathways: twisted nanoribbons transforming into either nanotubes at low water content or flat nanoribbons at high water content. The peptide packing in flat nanoribbons is predominantly modulated by POSS, diverting the system away from crystal formation, which is the absolute lowest energy state of pure peptide self-assemblies. For the first time, we have demonstrated that POSS can serve as a useful tool to adjust the interactions between cross-β strands, achieving fine-tuning of the pathway complexity (i.e., the kinetic and thermodynamic aspects of peptide self-assembly).

These CPEs feature a three-dimensional rigid skeleton network composed of polyacrylonitrile/metal–organic frameworks/ionic liquids (PAN/MOFs/ILs), creating continuous and efficient Li + transport channels: MOFs impart rigidity, PEO acts as a cushioning outer layer to enhance interfacial compatibility, and ILs reduce interfacial resistance.

Transesterification is inhibited during the ROP by use of a two-component organocatalyst.

Also interestingly, ethylene glycol and water are found to further accelerate the amidation while suppressing backbone degradation.

  @article{ , abstract = {Climate change driving by greenhouse gas emissions from petroleum-based energy has garnered significant attention. Renewable energy production via a sustainable system that integrates the cell factory and visible-light-driven photocatalysts offers a novel approach for upcycling methane and addressing global energy challenges. Here, an auto-activated biohybrid system driven by solar energy is developed for converting methane into hydrogen fuel, which incorporated thienoviologen (S-MV 2+ ) and genetically engineered methanotrophic bacteria. In this system, S-MV 2+ functioned as photosensitizer and electron mediator, capturing solar energy and supplying electrons for an enzyme-catalyzed bioprocess. The genetically modified Methylomicrobium buryatense 5GB1 mutant, lacking methanol dehydrogenase but overexpressing hydrogenase, is able to convert methane into methanol that maintains the electron flow cycle by quenching photogenerated holes for both hydrogen biosynthesis and methane oxidation. Finally, the highest H 2 production of 272.96 μM from this biohybrid system was achieved with methanol as a sacrificial agent generated by the H 2 -producing mutant, resulting in a 140-fold enhancement. This innovative method showcases the potential of coupling photocatalysis with methanotrophic biocatalysis for sustainable energy production. Additionally, the system introduces a new strategy for self-regeneration of sacrificial agents, offering a promising avenue for hydrogen production using greenhouse gases in an eco-friendly manner.}, archive = {J_ANGEW}, author = {Ziyue Jiao and Guoping Li and Shuqi Guo and Weiting Wang and Qianzi Hou and Yawen Li and Wenqiang Ma and Gang He and Qiang Fei}, doi = {10.1002/anie.202419973}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {7}, pages = {e202419973}, shortjournal = {Angew.

  @article{ , abstract = {The widespread adoption of rechargeable alkaline batteries is plagued by the performance-limiting metal anodes, which are prone to (electro)chemical corrosion and raise environmental or economic concerns. Organic redox-active materials offer a potential solution, but they typically struggle with dissolution-induced degradation and insufficiently negative reduction potentials. Herein, we introduce benzo[c]cinnoline and its derivatives (collectively referred to as BCCs), a class of aromatic azo compounds with fused-ring structure, as promising organic anode materials. BCCs exhibit pronounced aromaticity and Brønsted basicity, conferring low reduction potentials and intrinsic insolubility in alkaline solutions. Paired with the industrially established nickel hydroxide cathode, these batteries deliver excellent capacity (297 mAh g −1 anode ), high output voltage of 1.3 V, and extended cycle life (≈16000 cycles). Notably, they also operate efficiently at extremely low temperatures down to −85 °C with an 8 M KOH electrolyte. We further explore the feasibility for all-organic alkaline batteries by paring BCCs with the dihydro form of 4,4’-azopyridine, utilizing azo compounds for both anode and cathodes. This chemistry harnesses the unique properties of small organic molecules to enable all-organic batteries with high capacity of 236 mAh g –1 , fast charging at 1200 C, and easy recyclability.}, archive = {J_ANGEW}, author = {Jiapeng Zhao and Wenjin Zhang and Dawei Du and Zhihao Liu and Weixiao Ji and He Huang and Siping Pang}, doi = {10.1002/anie.202419887}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {7}, pages = {e202419887}, shortjournal = {Angew.

Stronger proton affinity of -OH in PD can break bulk-H 2 O hydrogen-bond-network to inhibit the activity of water, and electron affinity can enhance electron acceptation capability, which ensures that PD is preferentially bound to electrode material over H 2 O.

  @article{ , abstract = {The rapid reaction between lead iodide (PbI 2 ) and formamidinium iodide (FAI) complicates the fabrication of high-quality formamidinium lead iodide (FAPbI 3 ) films. Conventional methods, such as using nonvolatile small molecular additives to slow the reaction, often result in buried interfacial voids and molecule diffusion, compromising the devices’ operational stability. In this study, we introduced a molecular “thruster”—a hypervalent iodine (III) compound with three carbonyl groups and a C − −I + bond—that possesses coordination and dissociation abilities, enabling programed modulation of perovskite-film growth kinetics. Initially, the three carbonyl groups coordinate with PbI 2 to slow the reaction between FAI and PbI 2 , preventing δ-phase formation. As temperature rises, the C − −I + bond dissociates, promoting perovskite growth and the dissociated product iodobenzene will promote solvent volatilization, thus avoiding buried interfacial voids. Another product, a carbene compound with eight lone pair electrons sufficiently passivate the undercoordinated Pb 2+ defects and anchors at grain boundaries without diffusion. Consequently, the resultant FAPbI 3 film displays high-quality with enhanced phase purity, compact morphology, and reduced defects.

However, controlling the independence of stimuli-responses in these systems is challenging. Herein, we exploit halogen bonding (XB) as a reversible network element to regulate the photoresponsive and adaptive behavior of supramolecular polymers. To this end, we have designed a two-component system comprising an amphiphilic XB acceptor with the ability to self-assemble in aqueous media ( OPE-Py ) and a molecule with a dual photoresponsive and XB donor function [ ( E )-Azo-I ]. OPE-Py self-assembles in aqueous media into supramolecular polymers, which transform into nanoparticle assemblies upon co-assembly with ( E )-Azo-I . Interestingly, a third type of assembly (2D sheets) is obtained if OPE-Py is treated with ( E )-Azo-I and exposed to photoirradiation. At ambient conditions, both nanoparticles and 2D sheets remain invariant over time. However, heating dissociates the XB interactions present in both assemblies, resulting in their transformation to the original fiber-like morphology of OPE-Py . Thus, breaking the communication between self-assembly and the stimuli-responses upon heating restores the original state of the system, drawing parallels to feedback loops in programming language.

  @article{ , abstract = {Global plastic production exceeded 400 million tons in 2022, urgently demanding improved waste management and recycling strategies for a circular plastic economy. While the enzymatic hydrolysis of polyethylene terephthalate (PET) has become feasible on industrial scales, efficient enzymes targeting other hydrolyzable plastic types, such as polyurethanes (PURs), are lacking. Recently, enzymes of the amidase signature (AS) family, capable of cleaving urethane bonds in a polyether-PUR analog and a linear polyester-PUR, have been identified. Herein, we present high-resolution crystal structures of the AS enzyme UMG-SP3 in three states: ligand-free, bound with a suicidal inhibitor mimicking the transition state, and bound with a monomeric PUR degradation product. Besides revealing the conserved core and catalytic triad akin to other AS family members, the UMG-SP3 structures show remarkable flexibility of loop regions. Particularly, Arg209 in loop 3 adopts two induced-fit conformations upon ligand binding. Through structure-guided kinetic studies and enzyme engineering, we mapped structural key elements that determine the enhanced hydrolysis of urethane and amide bonds in various small molecules, including a linear PUR fragment analog.

The rate and position of the exchange equilibrium strongly depend on the reaction conditions as well as the substitution pattern on the methylene indoline fragments.

Here we describe a novel and robust method to control the spatial position of lipid domains of liquid-ordered (Lo)/liquid-disordered (Ld) phase in giant unilamellar vesicles. Our strategy consists in confining Lo/Ld phase-separating GUVs in microfluidic channels to define free curved regions where the minority-phase domains localize and coalesce by decreasing the line energy through domain fusion. We show that this process is governed by the respective fraction of the two phases, and not by the chemical nature of the lipids involved. The spatial position and number of domains are controlled by the design of the confining microchannel and could result in polarized GUVs with a controllable number of poles.

  @article{ , abstract = {Metal-ion batteries (such as lithium-ion batteries) are very popular energy-storage devices nowadays.

Here, we propose that electrochemical energy-storage materials with negative-thermal-expansion (NTE) behavior can enable good low-temperature electrochemical performance, which becomes a new strategy to tackle the low-temperature issues of metal-ion batteries. LiTi 2 (PO 4 ) 3 (LTP) with an a -direction thermal expansion coefficient of −1.1×10 − K −1 is used as a model material. As the temperature decreases, the transverse vibration of O atoms not only increases the transverse distances among O atoms connected to Li/Ti atoms, but also widens the Li + -transport channels and enlarges the Li + -insertion sites along the [12 ] direction, which are mainly controlled by the lattice parameter a . Consequently, carbon-coated LTP (C–LTP) retains good electrochemical performance at −10 °C, including fast Li + diffusivity (84 % of that at 25 °C), large capacity (96 % of the theoretical capacity), and superior rate capability (83 % capacity retention at 5 C vs. 0.5 C). Moreover, the more open crystal structure of LTP at the lower temperature allows smaller maximum unit-cell-volume expansion, resulting in better cycling stability of C–LTP at −10 °C (96.8 % capacity retention over 1000 cycles at 2 C).}, archive = {J_ANGEW}, author = {Qiao Li and Liting Yang and Guisheng Liang and Jiahui Yu and Shaowu Huang and Liming Wu and Chunfu Lin and Renchao Che}, doi = {10.1002/anie.202419300}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {7}, pages = {e202419300}, shortjournal = {Angew.

Therefore, we establish a new set of assay conditions that enable highly efficient seed amplification in plates without any shaking. However, the same set of conditions displayed a very different behavior upon transfer to a microfluidic platform where no amplification was observed. We demonstrate that this is caused by the suppression of all secondary processes that could amplify the seeds in the complete absence of mechanical perturbations inside the microdroplets. We further show that the amplification inside droplets can be achieved by subjecting the microemulsions to high-frequency vibrations using a piezo device. Taken together, our results provide novel insights into the physical requirements of alpha-synuclein seed amplification and demonstrate a pathway towards the development of effective digital SAAs.}, archive = {J_ANGEW}, author = {Azad Farzadfard and Thomas O.

Comparisons with structural analogues highlighted the superior photocatalytic activity of this linear semiconductor, on account of its fully conjugated architecture. The associated excited-state reactivity enabled the transformation of various amines into imines in batch and continuous flow reactors together with straightforward photocatalyst recycling. Mechanistic investigations revealed concomitant photoredox and energy transfer pathways, that led to the formation of the desired products.

Herein, three types of ( ortho -, meta -, and para -) azopyridine polymers hinged with flexible alkyl chain are synthesized, in which meta -azopyridine polymer exhibits striking photothermal storage capacity of 430 J/g, providing a feasibility solution for developing high energy density Azo-based STFs. Furthermore, a stable two-phase hybrid system was innovatively constructed by combining the meta -azopyridine polymer with organic phase change materials leveraging hydrogen bonds and van der Waals interactions to collectively harness phase change energy and photothermal energy. The organic phase change material not only supplies additional phase change latent heat but also serves as a solvent, offering abundant free volume for the photo-induced isomerization of the azopyridine chromophores, which successfully circumvents the low charging efficiency in the condensed state and reliance on solvent-assisted charging in traditional Azo-based STFs.

In this study, modulation of SMSI was achieved on rutile-supported Pt nanoparticles (NP) over high-temperature CO 2 hydrogenation. The encapsulation of Pt NP surfaces with TiO 2– x overlayers is precisely controlled by the defects. It is found that oxygen vacancy defects significantly enhance the catalytic stability of Pt/rutile under high-temperature reverse water-gas shift (RWGS) reaction by inhibiting the occurrence of SMSI. Pt/rutile with oxygen vacancies achieves a 301 mol CO ⋅ g M −1 ⋅ h −1 space time yield and considerably catalytic stability (decreased by 8 %) at 800 °C over 100 h time-on-stream. Density functional theory (DFT) calculations suggest that the adsorption capacity of Pt NP on the rutile overlayer can be reduced by increasing electron density.

This procedure inevitably increases molecular weight, often accompanied by undesired increased lipophilicity. Removing structural elements from natural products is not always tolerated. This is also the case for the antibiotic fidaxomicin (Fdx), where every structural component has been shown to be crucial for antibiotic activity. In this work, we demonstrate how the residue switching approach can maintain biological activity of Fdx derivatives by replacing the rhamnoside-dichlorohomoorsellinate moiety of Fdx with smaller, more polar building blocks. We used palladium-catalysed allylic substitution to selectively install N -nucleophiles on the core of Fdx. The new derivatives were designed to mimic the binding of Fdx to the bacterial RNA polymerase. Evaluation against Mycobacterium tuberculosis , Clostridioides difficile , and the Gram-negative model organism Caulobacter crescentus demonstrated that the newly introduced residues can restore antibiotic activity, which was further supported by on-target RNA polymerase assays. We combined the allylic substitution with an organocatalysed novioside acylation protocol to enable the functionalisation of two vectors on Fdx in one pot.

Computational analysis indicates this is due to a highly polarised BO bonding interaction combined with modest BO multiple bond character. While the polarisation of the BO bond on AlCl 3 coordination enhances the Lewis acidity at boron it also reduces the basicity at oxygen and the latter is key to accessing a base-free oxoborane.

Here, we propose a strategy to simultaneously remove superficial defect layer and solidify the surface by soaking air-fabricated perovskite film into low-polar organic esters at elevated temperature to trigger an in situ dynamic surface lattice disassemble and reconstruction process. Molecular dynamics simulations and experimental results indicate that the inorganic CsPbI 2 Br perovskite is first dissolved and then the Br-rich phase is recrystallized at solid–liquid interface owing to the balance between weak solubility and high-temperature induced annealing process, thus hardening the soft surface and releasing the lattice tensile stress, which benefits the minimization of interfacial recombination and improvement of the structural stability. As a result, we prepare a carbon-based CsPbI 2 Br device in complete air without precise control on humidity, achieving a champion efficiency of 15.37 % with excellent resistance to harsh attackers.

However, designing efficient and highly stable non-noble metal catalysts for two-electron oxygen reduction reaction (2e − ORR) in seawater environment remains a challenging task due to the corrosive and toxic nature of chloride ions (Cl − ). Herein, we present, for the first time, a novel nitrogen and oxygen self-doped defect-rich nanocarbon (NO-DC 700 ) catalyst, derived from silk fiber, which addresses these challenges with low toxicity, cost-effectiveness, and high adaptability. The obtained NO-DC 700 catalyst demonstrates an impressive H 2 O 2 production rate of up to 4997 mg L −1 h −1 , a high Faradaic efficiency of 96.5 %, and produces 4.3 wt % H 2 O 2 after 20 hours of stable operation, placing it among the highest-performing catalysts reported in neutral electrolytes. Theoretical calculations reveal that NO-DC 700 ′s superior 2e − ORR performance is due to the synergistic effect of graphitic nitrogen and C-OH, which inhibits Cl − adsorption and promotes *OOH adsorption. Additionally, integrating 2e − ORR with Fenton-like technology enables rapid degradation of organic pollutants and effective inactivation of seawater algae, offering significant potential for mitigating coastal eutrophication and red tide pollution.

Conventional opioid designs rely on the covalent conjugation of fentanyl analogues to immunogenic carrier proteins that hold the inherent capacity of mounting immunodominant responses.

  @article{ , abstract = {Minimizing energy loss is crucial for breaking through the efficiency bottleneck of organic solar cells (OSCs). The main mechanism of energy loss can be attributed to non-radiative recombination energy loss (Δ E nr ) that occurs due to exciton–vibration coupling. To tackle this challenge, tuning intramolecular noncovalent interactions is strategically utilized to tailor novel fused ring electron acceptors (FREAs). Upon comprehensive analysis of both theoretical and experimental results, this approach can effectively enhance molecular rigidity, suppress structural relaxation, reduce exciton reorganization energy, and weakens exciton–vibration coupling strength. Consequently, the binary OSC device based on Y-SeSe, which features dual strong intramolecular Se ⋅ ⋅ ⋅ O noncovalent interactions, achieves an outstanding power conversion efficiency (PCE) of 19.49 %, accompanied by an extremely small Δ E nr of 0.184 eV, much lower than those of Y-SS and Y-SSe based devices with weaker intramolecular noncovalent interactions. These achievements not only set an efficiency record for selenium-containing OSCs, but also mark the lowest reported Δ E nr value among high-performance binary devices. Furthermore, the ternary blend device showcases a remarkable PCE of 20.51 %, one of the highest PCEs for single-junction OSCs.

More importantly, using NIR-II dual-ratiometric FL/PA imaging, we successfully demonstrated that the probe could be used to accurately quantify the fluctuating H 2 S 2 levels in the liver-injury mouse models induced by lipopolysaccharides or metformin drugs. Overall, this study not only presents a promising tool for H 2 S 2 -related pathological research, but also provides a unique recognition site that may be generalized for designing more useful H 2 S 2 imaging agents in the future.}, archive = {J_ANGEW}, author = {Bangping Hu and Qinian Liu and Yulan Jiang and Yujie Huang and Huiquan Ji and Jiqi Zhang and Xia Wang and Xing-Can Shen and Hua Chen}, doi = {10.1002/anie.202418378}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {7}, pages = {e202418378}, shortjournal = {Angew.

  @article{ , abstract = {Despite advances in the controlled reconfiguration of DNA structures for biological applications, the dearth of strategies that allow for orthogonal regulation of immune pathways remains a challenge. Here, we report for the first time an endogenous and exogenous tandem-regulated DNA assembly strategy that enables orthogonally controlled stimulation of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway. A DNA motif containing two palindromic sequences is engineered with an abasic site (AP)-connected blocking sequence to inhibit its self-assembly function, while apurinic/apyrimidinic endonuclease 1 (APE1)-triggered enzymatic cleavage of the AP site enables the reconfiguration and self-assembly of DNA motif into long double-stranded structures, thus realizing allosteric activation of the catalytic activity of cGAS to produce 2’3’-cyclic-GMP-AMP for STING stimulation. Importantly, we demonstrate that APE1-regulated DNA assembly allows for cell-selective activation of cGAS–STING signaling. Furthermore, by re-engineering the DNA motif with a photocleavable group, enzyme-triggered DNA assembly allows the cGAS–STING stimulation to operate (switched “ON”), whereas light-mediated fragmentation of the double-stranded DNA enables termination of such stimulation (switched “OFF”), thereby achieving orthogonal control over immune regulation.

  @article{ , abstract = {The electrochemical conversion of low-concentration CO 2 feedstock to value-added chemicals and fuels is a promising pathway for achieving direct valorization of waste gas streams. However, this is challenging due to significant competition from the hydrogen evolution reaction (HER) and lowered CO 2 reduction (CO 2 R) kinetics as compared to systems that employ pure CO 2 . Here we show that terephthalic acid (TPA) functionalization can boost selectivity towards CO 2 R and suppress HER over a range of catalysts including Bi, Cu and Zn. For instance, TPA functionalized Bi attained a formate Faradaic efficiency (FE HCOO- ) of 96.3 % at 300 mA cm −2 with pure CO 2 feedstock. Density functional theory simulations indicate that this is because TPA functionalization modulates the binding energies of the key reaction intermediates *OCHO and *H. With low-concentration feedstock (15 % CO 2 ) at 100 mA cm −2 , we achieved a high FE HCOO- of 85.8 %, which was double that of an unmodified Bi catalyst. Using an electrolyzer with a porous solid electrolyte layer, we successfully showcase 30 h of continuous high-purity formic acid production with a 5 % CO 2 feed.

Experimental and molecular dynamics modeling proved the efficient dynamic hydrogen bond exchange at 60 °C, significantly lower than the actuating temperature of the LCE. This gave rise to the reversible and robust adhesion of the same collection of LCE modules capable of being built into different bilayers and performing various morphing upon a short thermal stimulation. Therefore, we demonstrated that these comparatively weak cross-links enabled reconfiguration of the LCE actuator.

  @article{ , abstract = {Electrically driven light-emitting diodes (ED LEDs) based on 3D metal halide perovskites have seen remarkable advancements during the past decade. However, the highest-performing devices are largely based on lead-containing 3D perovskites, presenting two key challenges – toxicity and stability – that must be addressed for commercialization. Reducing structural dimensionality and incorporating non-lead metals present promising pathways to address these issues. Although research on ED LEDs based on low-dimensional, lead-free metal halides (LD LFMHs) is growing, their performance still significantly lags behind that of 3D lead halide perovskites. This review seeks to deliver a comprehensive overview of ED LEDs based on LD LFMHs, covering a brief history of their development, methods for material synthesis, luminescence mechanisms, and applications in electroluminescent devices.

The helicene structure and the photophysical features can be easily tuned by changing the connecting position of the nanographene to the carbazole core (2,7− and 3,6−). Single-crystal X-ray diffraction analysis confirmed the formation of nanographenes with bent and helical conformations. Both derivatives exhibited thermally activated delayed fluorescence at room temperature and phosphorescence at low temperatures. Notably, the nanographene with the bent structure displayed an impressive red afterglow lasting over 30 seconds, in contrast to the very weak afterglow observed in the helical structure. DFT calculations revealed the existence of an isoenergetic higher triplet state (T 8 ) and comparatively weak spin-orbit coupling (T 1 -S 0 ), thereby enabling the bent nanographene to exhibit a long-lived component and strong afterglow.

The polycatenated framework with optimized pore size and regularity, exhibiting significant improvements over traditional PSP MOFs by resolving the critical contradiction of balancing C 2 H 2 uptake (98.5 cm 3 g −1 at 298 K, 100 kPa) and selectivity of C 2 H 2 /CO 2 (3.4), C 2 H 2 /C 2 H 4 (5.9), and C 2 H 2 /CH 4 (96.4) in a MOF. Breakthrough experiments confirm high-purity C 2 H 4 (>99.9 %) and high C 2 H 2 productivity from binary and ternary mixtures. Notably, Ni-dcpp-bpy exhibits excellent water stability, scalability, and regenerability after 20 cycles for separating C 2 H 2 /CO 2 .

  @article{ , abstract = {Nature produces ATP, the energy currency, by converting solar energy (photophosphorylation) and chemical energy (substrate-level phosphorylation and oxidative phosphorylation). Green electricity, as a significant and sustainable energy carrier, plays a crucial role in achieving a carbon-neutral society. In this work, we established and verified a novel electrodriven phosphorylation method. Spinach thylakoid membranes (TMs), enriched with ATPases, were isolated and constructed into planar TMs (pTMs) on a proton exchange membrane (PEM), effectively imparting the traditional PEM with the biological function of ATP regeneration. Following the optimization of TMs concentration and incubation time, the biological PEM was integrated into a two-compartment electrochemical cell, where ATP was successfully synthesized by ATPase of pTMs, triggered by the proton gradient potential generated during electrochemical water splitting. When a constant voltage of 3 V was applied to the electrochemical cells, ATP was synthesized at a rate of 3.16 μM min −1 μg Chl −1 , approximately twice the rate of ΔpH-driven ATP synthesis.

  @article{ , abstract = {The nonlinear chiroptical properties of chiral metal halide perovskite has attracted substantial attention in recent years. In order to overcome the inherent limitations of metal halide, such as high costs, potential toxicity, challenges with recycling, especially the limited laser-induced damage threshold (LDT), we have successfully constructed the first chiral metal-free anti-perovskite, with the aim of utilizing it in second harmonic generation-circular dichroism (SHG-CD). Moreover, the anti-perovskite composed entirely of small organic ions typically display a more extensive transparent window, which could contribute a high LDT. Herein two chiral metal-free anti-perovskites, R / S -MCN [( R / S -MBA) 6 Cl(NH 4 Cl 6 )] were constructed, and exhibit strong second-harmonic generation response from 800 to 980 nm. The second-order nonlinear optical coefficient of the chiral metal-free anti-perovskite reaches 0.89 pm/V, which is higher than that of commercial Y-cut quartz. Most importantly, both R - and S -MCN exhibit a large nonlinear optical activity with a high SHG dissymmetry factor ( g SHG-CD ) of 0.60 and a high laser-induced damage threshold of 71 mJ/cm 2 , which is higher than that of most reported chiral perovskites.

Artificial molecular systems that—to some extent—imitate tasks of membrane-embedded proteins are increasingly developed, however, they are usually controlled through responsive units in their core structure. Here we present an alternative approach based on an amphiphilic stiff-stilbene derivative that enables control of membrane fluidity by light. The fluidity increase upon E -to- Z isomerization is shown to enhance the activity of known synthetic anion transporters as a result of a higher mobility. The photoisomerization process is studied by UV/Vis and 1 H NMR spectroscopy in solution and in POPC vesicles, where the light-induced changes in fluidity and hence, activity of anion transporters, are monitored by fluorescence spectroscopy. Dynamic light-scattering (DLS) and cryo-EM studies show that vesicle integrity is not impaired by photoswitching. Our work introduces a versatile approach to control solute transport by carrier molecules. Moreover, the photocontrol over membrane fluidity and, with that, mobility could eventually be used for directed motion, which we expect to be key in achieving active transport in the future.}, archive = {J_ANGEW}, author = {Jasper E.

The diverse conjugation systems within covalent organic frameworks (COFs) can significantly impact photon absorption, energy level structures, charge separation and migration kinetics. Consequently, these limitations often manifest as unsatisfactory kinetic behavior, which adversely affects the photocatalytic activity of COFs. To address these challenges, we propose a methoxy (−OMe) molecular engineering strategy designed to enhance charge carrier kinetics and mitigate mass transfer resistance. Through strategic modulation of the position and quantity of −OMe units, we can effectively manipulate the p-π conjugation, thereby enhancing charge separation and migration. Moreover, COFs enriched with −OMe moieties exhibit enhanced mass transfer dynamics due to the hydrophilic nature of methoxy groups, which facilitate the diffusion of reactants and products within the porous structure.

Noteworthy, the areal capacity can reach 7.8 mAh cm −2 at 0.05 C and a retention capacity of 4.7 mAh cm −2 after 100 cycles at 0.2 C for Ni−NSC based Li−S battery with sulfur loading of 5.88 mg cm −2 .

These results are in agreement with a mechanism in which MA -mediated photo upcycling of PS to BAc occurs through the abstraction of benzylic H atoms by reactive oxygen species generated by energy or electron transfer from the excited state of MA . Addition of triplet O 2 to these radicals, followed by intra- or inter-molecular hydrogen atom transfer (HAT) generates C- or O-centered radicals then undergoing β-scission or hydroperoxide fragmentation.

The number density of Ag NCs is strongly dependent on the starting concentration of PVP chains demonstrating PVP end-groups play an important role in the nucleation of NCs. The concentration of Ag + is 2 orders of magnitude higher than the end-groups suggesting ethylene glycol must participate in the reduction of Ag + during growth.

Here we propose a multi-concentration stratagem propelled by entropy reinforcement to enhance the electronic structure disorder (ESD) at high desodiation states for impeding undesired oxygen mobility and ensuring controlled oxygen activity, elucidated by density functional theory calculations. The increased disorder strengthens the reversible electrochemistry of lattice oxygen redox, leading to effectively suppressed P−O structural evolution and highly stable localized TMO 6 octahedral environments, as demonstrated by soft/hard X-ray absorption spectroscopy. Furthermore, through a comparative analysis of sodium-layered cathodes with different configuration entropy, we reveal that a high-entropy state induced by cationic disordering has the capacity to perturb cationic redox boundaries, significantly restraining the formation of detrimental O′3 phases.

This phenomenon has proved to be particularly important in water microdroplets, where the spontaneous oxidation of many species stable in bulk has been experimentally demonstrated. Different theories have been proposed to explain this finding, but it is currently believed that the role of interfacial electric fields is key. In this work, we have carried out a quantum chemistry study aimed at shedding some light on this question. We have studied two prototypical processes in which a hydroxide anion transfers its excess electron to either the water environment or a dioxygen molecule. To model the interface, we use a cluster of 21 water molecules immersed in an electric field, and we examine the energetics of the studied reactions as a function of field magnitude. Our results reveal that electric fields close to those estimated for the neat air–water interface (∼0.15 V ⋅ Å −1 ) have a moderate effect on the reaction energetics and that much stronger fields (>1 V ⋅ Å −1 ) are required to get spontaneous electron transfer.

In this study, we evaluate the critical role of excited-state proton-coupled electron transfer in the emission of metal NCs. Our findings demonstrate that hydronium ion (H 3 O + ) binding can trigger a nonlinear, pH-dependent excited-state concerted electron proton transfer (CEPT) reaction. This involves simultaneous electron transfer from the Au(0) core to the Au(I)−ATT (ATT denotes 6-aza-2-thiothymidine) surface and proton transfer from H 3 O + to the ATT ligand in a single step, greatly promoting vibrations and rotations of the Au(I)−ATT surface, resulting in substantial PL quenching of Au 10 (ATT) 6 NCs. Further analyses show that the unique CEPT dynamics are strongly influenced by the opposing effects of increased reorganization energy and a larger pre-exponential factor on the electron transfer rate. Moreover, the proposed excited-state CEPT process is found to be prevalent in core–shell relaxation metal NCs, such as Au 25 (SR) 18 (SR denotes thiolate) NCs, and serves as an important factor in limiting their PL emission.

The origin of the high 2°-selectivity was elucidated to be due to the relative barriers to carbodiimide elimination from the O -alkyl- N -(BR 2 )-isoureas. As the selectivity controlling step does not involve fluoride, this borane-mediated approach can be applied to other nucleophiles, as demonstrated by 2°-selective deoxychlorination using HCl occurring in preference to substitution of 1° and Bn analogues.

However, it imposes great complexity to realize a controllable degree of distortion by tuning the skeleton of blocks and the position of linker between blocks. Herein, we developed a facile strategy to rationally control the geometry distortion of OAs via a straightforward substitution of alkoxy side-chains on their blocks.

To date, however, the efficiency of subsequent optimisation campaigns has largely been low-throughput, constrained by the need for synthesis and purification of target compounds. We report an efficient platform for ‘direct-to-biology’ (D2B) screening of cysteine-targeting chloroacetamide RFs, wherein synthesis is performed in 384-well plates allowing direct assessment in downstream biological assays without purification. Here, the developed platform was used to optimise inhibitors of SARS-CoV-2 main protease (M Pro ), an established drug target for the treatment of COVID-19. An initial RF hit was developed into a series of potent inhibitors, and further exploration using D2B screening enabled a ‘switch’ to a reversible inhibitor series. This example of ligand discovery for M Pro illustrates the acceleration that D2B chemistry can offer for optimising RFs towards covalent inhibitor candidates, as well as providing future impetus to explore the evolution of RFs into non-covalent ligands.}, archive = {J_ANGEW}, author = {Harry Wilders and George Biggs and Sam M.

  @article{ , abstract = {The Chiral-Induced Spin Selectivity (CISS) effect has emerged as a fascinating phenomenon within the realm of electron's spin manipulation, showcasing a unique interplay between electron's spin and molecular chirality. Subsequent to its discovery, researchers have been actively involved in exploring the new chiral molecules as effective spin filters. In the realm of observing the CISS effect, the conventional approach has mandated the utilization of two distinct enantiomers of chiral molecules. However, this present study represents a significant advancement by demonstrating the ability to control both spin states of electrons in a single system. In this work, we have demonstrated the preparation of chiral metal–organic frameworks (MOFs) via a “spontaneous resolution” process, obviating the requirement for chiral sources. This resulted in the production of chiral crystals exhibiting opposite handedness ( 1P and 1M) and these crystals were subsequently employed as a new class of spin filters based on CISS effect. Remarkably, this work signifies the first instance of achieving dual signature of spin selectivity from a single and exclusively achiral system through a spontaneous resolution process. This holds immense potential as it facilitates the production of two distinct spin-filtering materials from a unified system. Furthermore, we investigated the contact potential differences (CPD) of these chiral crystals and, for the first time, associated it with the preferential spin transport properties. Our findings revealed a correlation between the CPD and the chirality of the crystals, as well as the magnetization orientations of the ferromagnetic substrate, which can be elucidated by the CISS effect. In overall, the significant findings achieved using these robust and easily synthesized MOF crystals without the requirement for chiral medium represent a crucial advancement in enhancing the effectiveness of spin filtering materials to produce spintronic devices.}, archive = {J_ANGEW}, author = {Rabia Garg and Pravesh Singh Bisht and Subash Chandra Sahoo and Amit Kumar Mondal}, doi = {10.1002/anie.202418222}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {6}, pages = {e202418222}, shortjournal = {Angew.

In this work, we propose an in situ granule reconstruction strategy to directly regenerate spent LFP black mass (S−BM) using glycerol in industry settings. The hydroxyl groups abundant in glycerol serves as electron donor that help reduce Fe (III) and repair Fe−Li antisite defects ( Fe Li ). Additionally, the chelating properties of glycerol intervene with structurally disintegrated particles, inhibiting Oswald ripening effect and promoting bonding of grain boundaries to generate lamellar microcrystals with homogeneous grain size, recover their morphology and crystal structure after a facile annealing procedure. Furthermore, the regenerated LFP restores Fe−O bonds which further inhibits structural distortion and improve Li + migration kinetics.

Transforming end-of-life PET into (bio)degradable polyester offers a novel approach to managing its waste.

The polyesters with variable x / y compositions ranging from 100/0 to 0/100 can be achieved, and the molecular weight (Mw) can be maintained when x / y >87/13 due to the nonobvious depolymerization. Pronounced depolymerization would occur with deeper hydrogenation, which generates a blend of PET-PECHD and polyethylene-1,4-cyclohexanedicarboxylate (PECHD) with lower Mw, and finally a single-type polymer PECHD.

To optimize reaction conditions for selected substrates, LLMs were prompted to generate code that iteratively improved yields. This human-AI collaboration proved effective, efficiently identifying high-yield conditions for 8 drug-like substances or intermediates. Notably, we benchmarked the accuracy and reliability of 12 different LLMs–including LLaMA series, Claude series, OpenAI o1, and GPT-4-on code generation and function calling related to ML based on natural language prompts given by chemists to showcase potentials for accelerating research across four diverse tasks. In addition, we collected an experimental benchmark dataset comprising 1071 reaction conditions and yields for electrochemical C−H oxidation reactions.}, archive = {J_ANGEW}, author = {Zhiling Zheng and Federico Florit and Brooke Jin and Haoyang Wu and Shih-Cheng Li and Kakasaheb Y.

  @article{ , abstract = {Iodine cathode in aqueous battery has drawn great attention due to its high energy density and high safety. However, iodine has extremely low conductivity of 1×10 −7 S cm −1 , which usually results in low specific capacity. In this work, a PVA-hydrogel layer was designed to enhance the areal capacity of zinc-iodine cell. The areal capacity of PVA-hydrogel layer modified CNT cathode showed twice as higher capacity than that of pure CNT film in a dual-plating cell, The significant enhancement of the capacity was attributed to the fast iodine transport in the PVA-hydrogel layer. Besides, the strong interaction between PVA chain and polyiodide anions prevented the shuttle effect. The PVA modified CNT cathode could stably operate for over 3000 hours with remarkably higher capacity and cycle life. We analyzed the uniquely fast transport behavior of polyiodides in PVA hydrogel by in situ Raman spectroscopy, in situ optical micrography, as well as DFT calculations. It was found that the strong binding force together with lower dissociation energy of iodine on PVA chain is the dominate reason for reduced shuttle effect and fast polyiodide transport. As a result, the assembled PVA-I 2 pouch cells showed excellent performance in both dual-plating cells and conventional-type cells.}, archive = {J_ANGEW}, author = {Dandan Yin and Boyang Li and Lanya Zhao and Na Gao and Yanan Zhang and Jie Feng and Xiaofeng Cui and Chunhui Xiao and Yaqiong Su and Kai Xi and Shujiang Ding and Hongyang Zhao}, doi = {10.1002/anie.202418069}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {6}, pages = {e202418069}, shortjournal = {Angew.

In the latter, interfacial engineering has enabled efficient transport, higher device stability, and novel functionality. Mechanoresistivity – the change in electrical behaviour in response to a mechanical stimulus and a pathway to extremely sensitive force sensors – is amongst the most studied phenomena in molecular electronics, and the molecule-electrode interface plays a pivotal role in its emergence, reproducibility, and magnitude. In this contribution, we show that organometallic molecular wires incorporating a Pt(II) cation show mechanoresistive behaviour of exceptional magnitude, with conductance modulations of more than three orders of magnitude upon compression by as little as 1 nm. We synthesised series of cyclometalated Pt(II) molecular wires, and used scanning tunnelling microscopy – break junction techniques to characterise their electromechanical behaviour. Mechanoresistivity arises from an interaction between the Pt(II) cation and the Au electrode triggered by mechanical compression of the single-molecule device, and theoretical modelling confirms this hypothesis.

Here we report the first PeT-based turn-on probe that acts via a chemiluminescent operation mode. We designed, synthesized, and evaluated a novel chemiluminescent probe, featuring a PeT-based turn-on mechanism. The probe consists of a phenoxy-1,2-dioxetane, linked to an azide unit that acts as a PeT quencher. Upon cycloaddition of a strained cycloalkyne with the azide, a triazole-dioxetane is formed, which undergoes relatively slow chemiexcitation, resulting in a measurement window with an exceptionally high signal-to-noise ratio (over 5000-fold). The PeT-dioxetane probe could effectively detect and image two model proteins labeled with strained cycloalkyne units (Myc-DBCO and Max-DBCO) through either NHS or maleimide conjugations. Comparative analysis shows that our PeT-based chemiluminescent probe significantly outperforms a commercially available fluorescent analog.

In this work, we design two oxy-bithiophene-based CP series, each featuring progressively extended alkyl spacer lengths and two distinct molecular weight (MW) distributions. Using operando characterisations, we evaluate the (spectro)electrochemical and swelling properties of the polymer thin films, and their performance in organic field-effect transistors and organic electrochemical transistors. Surprisingly, alkyl spacers negatively impact the hole mobility of our polymers, with higher MW amplifying this effect. Using molecular dynamics simulations, we show that it is thermodynamically favourable for adjacent non-polar alkyl spacers to aggregate in polar electrolytes, leading to backbone twisting.

In this study, we synthesized two isomers, CZTBT and LVTBT, which possessed distinct configurations. LVTBT, characterized by a flatter molecular configuration, exhibited an extended absorption wavelength and a higher molar extinction coefficient.

The strong electron deficiency of diketopyrrolopyrrole (DPP) makes its methyl substituents readily activated upon the cocatalysis of L-proline and 4-dimethylaminopyridine in aqueous solution to conduct dynamic condensation with tritopic aromatic aldehydes. The resulting COFs crystallized in an eclipsed AA stacking arrangement and featured abundant, regular nanochannels. Their robust vinyl DPP-linking mode enhanced donor-π-acceptor conjugation and promoted π-stacked alignment along the vertical direction. Consequently, the synthesized COFs exhibited band gaps as narrow as 1.02 eV and demonstrated excellent light-harvesting capability across the visible to near-infrared I (NIR-I) regions. Furthermore, the COFs could be converted into free-standing thin pellets through simple pressure casting, and show excellent photothermal response and cycling stability under different light sources.}, archive = {J_ANGEW}, author = {Zixing Zhang and Fancheng Meng and Xu Chi and Yang Jiao and Bai Xue and Xiaomeng Li and Fan Zhang}, doi = {10.1002/anie.202417805}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {6}, pages = {e202417805}, shortjournal = {Angew.

An interesting result of such membrane-lipid interplay is the reorganization of lipid domains together with membrane-bound proteins at the onset of cell division, suggesting functional significance of membrane compartments in the cell cycle. Here, by adopting the key bacterial division proteins MinC, MinD, MinE, FtsA and FtsZ as an archetypal spatial patterning system, we present a simple vesicle-based in vitro model to explore the mutual dependence of protein pattern formation and membrane heterogeneity. Like many other peripheral membrane proteins, Min proteins exhibit preferential binding and macro-scale pattern formation at L d domains, which leads to altered oscillation mode selection in phase-separated membrane compartments (GUVs). Moreover, incorporating bacterial division proteins within phase-separated GUVs leads to blebbing-like membrane deformations followed by the reorganization of L o domains aligning at the neck region of the bleb, which agrees well with the domain rearrangement in bacterial membranes immediately preceding the radial constriction process. Overall, the presented in vitro model system showcases a basic framework to better comprehend the cellular division mechanism in consideration of complex cellular lipid environments.}, archive = {J_ANGEW}, author = {Nishu Kanwa and Shunshi Kohyama and Leonard Fröhlich and Amogh Desai and Petra Schwille}, doi = {10.1002/anie.202417800}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {6}, pages = {e202417800}, shortjournal = {Angew.

High conservation of endogenous ligands and receptors makes the identification of selective ligands challenging. Previously identified antagonists mimic the C-terminus of peptide ligands and lack selectivity towards the closely related neuropeptide FF receptor 2 (NPFFR2) or the neuropeptide Y 1 receptor (Y 1 R). In a high-throughput screening, we identified the pentacyclic triterpenoid hederagenin ( 1 ) as a novel selective antagonist for the NPFFR1. Hederagenin ( 1 ) is a natural product isolated from Hedera helix (ivy). We characterized its mode of activity using in vitro and in silico methods, revealing an overlapping binding site of the small molecule with the orthosteric peptide agonists. Despite the high similarity of the orthosteric binding pockets of NPFFR1 and NPFFR2, hederagenin ( 1 ) shows strong subtype selectivity, particularly caused by slight differences in the shape of the binding pockets and the rigidity of the small molecule. Several residues inhibiting the activity of hederagenin ( 1 ) at the NPFFR2 were identified.

Using a fluorogenic hemicyanine as a model payload component, we show that a zwitterionic BAC linker improves labeling efficiency and reduces antibody aggregation when compared to a commonly used para -amino benzyl (PAB) linker as well as a cationic BAC. Cellular and in vivo fluorescence imaging studies demonstrate that the model payload is specifically released in antigen-expressing cells and tumors. The therapeutic potential of the BAC linker strategy was assessed using an MMAE payload, a potent microtubule-disrupting agent frequently used for ADC applications.

Middle REEs (MREEs), characterized by their intermediate ionic radii, are particularly challenging to separate without size-specific trapping mechanisms. In this study, we report a novel approach that synergistically combines heavy metal sequestration with size-selective separation, utilizing negatively charged glycopolymers to achieve the targeted separation of MREEs. We systematically investigated the binding affinities of these glycopolymers for various REEs, focusing on the selective isolation of MREEs through a controlled variation of glycopolymer properties, including degree of polymerization (DP) and charge density. Our findings reveal a distinctive U-shaped selectivity profile, with a marked preference for Samarium (Sm) and Europium (Eu) over other REEs such as Cerium (Ce), Gadolinium (Gd), and Holmium (Ho). This selectivity underscores the potential for designing tailored separation processes optimized for specific MREEs. Moreover, enrichment experiments demonstrated the practical viability of our methodology, achieving over 10 % selectivity for Sm in a Ce/Sm mixture with a 10 : 1 Ce/Sm ratio, a trend that held for Sm in a Ho/Sm Mixture with a 10 : 1 Ho/Sm ratio, indicating significant selectivity over both light and heavy REEs.

  @article{ , abstract = {Compact luminophores with long emission wavelengths have aroused considerable theoretical and practical interest. Organics with room-temperature phosphorescence (RTP) are also desirable for their longer lifetimes and larger Stokes shifts than fluorescence. Utilizing the low electronic transition energy intrinsic to thiocarbonyl compounds, electron-withdrawing groups were attached to the 4 H -pyran-4-thione core to further lower the excited state energies. The resulting mini-phosphors were doped into suitable polymer matrices. These purely organic, amorphous materials emitted near-infrared (NIR) RTP. Having a molar mass of only 162 g mol −1 , one of the phosphors emitted RTP that peaked at 750 nm, with a very large Stokes shift of 15485 cm −1 (403 nm). Thanks to the good processability of the polymer film, light-emitting diodes (LEDs) with NIR emission were easily fabricated by coating doped polymer on ultraviolet LEDs.

  @article{ , abstract = {The utilization of perovskite oxide as a catalyst for aqueous reactions is promising but challenging in stability. Here, we propose an in situ growth strategy that constructs an ultrathin protective skin on the Sr 0.9 Fe 0.81 Ta 0.09 Ni 0.1 O 3-δ perovskite surface and thus effectively solves the stability issue. Using a spherical aberration-corrected transmission electron microscope, we observe the coexistence of an angstrom-scale (~7 Å) Fe 2 O 3 protective skin and FeNi alloy nanoparticles. A number of alloy nanoparticles grow along with the skin and uniformly take root on the skin surface. Such a hierarchical structure can reconstruct the surface electronic structure and suppress the ion leaching of perovskite oxide in water. Benefiting from this unique structure, the catalyst has experienced a substantial increase (800 h, more than three orders of magnitude) in its stable operation time in water (for example, in a hydrogen evolution reaction). These results provide valuable insight into solid-solid phase transitions and have substantial implications for using structural defects at surfaces to modulate mass transport and transformation kinetics. Our strategy is sufficiently simple and can be used to subtly manipulate the catalyst structures to improve the performance of perovskite-based catalysts and potentially other oxide catalysts for a wide range of reactions.}, archive = {J_ANGEW}, author = {Wanglin Zhou and Fang Xu and Jinkun Tan and Zhengkun Liu and Guangru Zhang and Zhi Xu and Yinong Lyu and Wanqin Jin}, doi = {10.1002/anie.202417360}, journal = {Angewandte Chemie International Edition}, month = {2}, number = {6}, pages = {e202417360}, shortjournal = {Angew.

Subsequently, the pure planar p-n heterojunction (PHJ) OSCs based on green orthogonal solvents were prepared and exhibited comparable even greater performance to that of BHJ OSCs.

Initialized by chlorin e6 (Ce6), a pH-sensitive amphiphilic amino acid fluorenylmethoxycarbonyl-L-histidine (Fmoc-His) was assembled with Gd 3+ , luminol, and AgAuSe quantum dots (AAS QDs) to form FLAGC.

Subsequently, the acidity of tumor microenvironment triggers the rapid disassembly of FLAGC, exposing Luminol-AAS. myeloperoxidase (MPO) secreted by tumor-associated macrophages and neutrophils in SLNs mediates the oxidation of luminol, lighting up AAS QDs through the CRET process for precise diagnosis of metastatic lymph nodes.

To date, no biocatalysts have been developed for fluoromethylation of unactivated carbon centers. In this study, we found that the B12-dependent radical SAM methyltransferase (B12-RSMT) QCMT can fluoromethylate the glutamine Cα position of peptides with fluorinated SAM (F-SAM) generated in situ by the enzyme Acl HMT. QCMT can cleave F-SAM to produce the 5'-dA radical. The significant reaction intermediate CH 2 FCbI was characterized by HR-MS, 19 F NMR spectroscopy and X-ray crystallography.

However, such asymmetric transformation has remained undeveloped to date due to the lack of suitable chiral catalysts. Here, we report for the first time the enantioselective [3+2] annulation of aldimines with alkynes via C−H activation using chiral half-sandwich scandium catalysts. This protocol enabled the synthesis of diverse multi-substituted chiral 1-aminoindene derivatives with 100 % atom-efficiency, broad substrate scope, and high regio- and enantioselectivity. Density functional theory (DFT) analyses have revealed that a noncovalent C−H⋅⋅⋅π interaction between a tert -Bu substituent in the chiral cyclopentadienyl (Cp) ligand and the phenyl ring of an aromatic aldimine substrate played an important role in achieving a high level of enantioselectivity. This work not only offers an efficient and selective route for synthesizing a new family of chiral 1-aminoindene derivatives but also offers unprecedented insights into enantioselectivity control in chiral Cp-ligated metal catalysts.}, archive = {J_ANGEW}, author = {Aniket Mishra and Jiameng Hu and Xuefeng Cong and Qingde Zhuo and Masayoshi Nishiura and Gen Luo and Zhaomin Hou}, doi = {10.1002/anie.202419567}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {5}, pages = {e202419567}, shortjournal = {Angew.

The unique properties of non-active alkali metals promoted us to systematically explore the potential of A-site-doped MHPs for photocatalysis. Herein, we dope potassium (K + ) into CsPbBr 3 via an anti-solvent precipitation method and first reveal that the occupied locations of K + in CsPbBr 3 is lattice incorporation rather than surface segregation, which would change from A-site substitution to interstitial site in lattice with the increase of K + concentrations. Taking hydrogen (H 2 ) evolution as a model reaction, photocatalytic activity of CsPbBr 3 after K + doping could be significantly improved ~11-fold with A-site substitution, which is superior to that of interstitial site doping. Moreover, other alkali metals including lithium (Li), sodium (Na), and rubidium (Rb) doping give the same results.

The key is to find an effective photocatalyst to do the trick. Defect engineering of semiconductors with oxygen vacancies (OVs) is an emerging strategy for catalyst fabrication. OVs can trap electrons to promote charge separation and serving as adsorption sites for O 2 activation. However, the randomly distribution of OVs on the semiconductor surface often results in mismatching the charge carrier dynamics under irradiation, thus failing to fulfill the unique advantages of OVs for photoredox functions. Herein, we demonstrate that abundant OVs can be facilely generated and precisely located adjacent to the reductive sites on reducible oxide semiconductors such as tungsten oxide (WO 3 ) via a simple photochemistry strategy. Such photoinduced OVs are well suited for photocatalytic benzene oxidation with O 2 as they readily capture photogenerated electrons from the reductive sites of WO 3 to activate adsorbed O 2 . The oxygen-isotope-labeling experiments further confirm that the OVs also facilitate the integration of oxygen atoms from O 2 into phenol, revealing in detail the pathway for photocatalytic benzene hydroxylation.

Consequently, the obtained Bi@SA Cu−C achieves a state-of-the-art reversible capacity, ultrahigh rate capability, and long-term cycling durability.

  @article{ , abstract = {Afterglow materials have garnered significant interest due to distinct photophysical characteristics. However, it is still difficult to achieve long afterglow phosphorescence from organic molecules due to aggregation-caused quenching (ACQ) and energy dissipation. In addition, most materials reported so far have long afterglow emission only at room or even low temperatures, and mainly use UV light as an excitation source. In this work, we report a strategy to achieve high temperature long afterglow emission through the assembly of isolated 0D metal-organic cages (MOCs). In which, both ACQ and phosphorescence quenching effects are effectively mitigated by altering the stacking mode of organic chromophores through orthogonally anchoring into the edges of cubic MOCs. Furthermore, improvement in molecular rigidity, promotion of spin-orbit coupling and broadening of the absorption range are achieved through the MOC-engineering strategy. As a result, we successfully synthesized MOCs that can produce afterglow emission even after excitation by WLEDs at high temperatures (380 K). Moreover, the MOCs are capable of generating afterglow emissions when excited by mobile phone flashlight at room temperature. Given these features, the potential applications of MOCs in the visual identification of explosives, information encryption and multicolor display are explored.}, archive = {J_ANGEW}, author = {Zhong-Hao Wang and Chen-Hui Liu and Lin Zheng and Hui-Li Sun and Shao-Qi Guan and Zhong-Min Cao and Mei Pan and Cheng-Yong Su}, doi = {10.1002/anie.202417593}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {5}, pages = {e202417593}, shortjournal = {Angew.

  @article{ , abstract = {The intratumor microbiota results in the immunosuppressive microenvironment and facilitates tumor growth and metastasis. However, developing a synergistic therapy with antitumor, antibacterial, and antimetastatic effects faces enormous challenges. Here, we propose an innovative metal chelation therapy to effectively eliminate tumor and intratumor bacteria and suppress tumor metastasis. Different from traditional chelation therapy that only consumes metal elements, this therapy not only eliminates the crucial metal elements for tumor metabolism but also releases new metal ions with antitumor and antibacterial properties. Based on the high demand for copper in breast cancer, we prepare a fibrous therapeutic nanoagent (Zn-PEN) by chelating the copper chelator D-Penicillamine (D-PEN) with Zn 2+ . Firstly, Zn-PEN achieves dual inhibition of oxidative phosphorylation (OXPHOS) and glycolysis metabolism in breast cancer through copper depletion and Zn 2+ activated cGAS-STING pathway, thus inducing tumor cell death. Secondly, Zn-PEN has the capability to eradicate Fusobacterium nucleatum ( F. nucleatum ) in breast cancer, thereby mitigating its immunosuppressive impact on the tumor microenvironment. Finally, Zn-PEN effectively inhibits tumor metastasis through multiple routes, including the inhibition of epithelial-mesenchymal transition (EMT) process, activation of cGAS-STING pathway, and elimination with F. nucleatum . Therefore, we verify the feasibility of Zn-PEN mediated metal chelation therapy in a 4T1 model infected with F. nucleatum , providing a new therapeutic strategy for inhibiting tumor metastasis.}, archive = {J_ANGEW}, author = {Yulin Xie and Junrong Wang and Lei Li and Man Wang and Jikai Sun and Jiaying Chang and Jun Lin and Chunxia Li}, doi = {10.1002/anie.202417592}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {5}, pages = {e202417592}, shortjournal = {Angew.

By employing a “2+1” bioinspired strategy, we stepwise designed and assembled super-foldable components, from substrates to electrodes, and to ultimately device. This bioinspired approach completely disperses folding stress and thus prevents the breakage of chemical bonds, enabling the successful fabrication of the first super-foldable ion battery.

Remarkably, after 500,000 true-folding cycles, the battery's microstructure remains intact with no significant degradation of electrochemical performance. Real-time dynamic folding observations reveal an M-shaped folding structure within the bioinspired materials, which effectively disperses stress via bulged layers, dispersed arcs, and slidable microgrooves that work together across different directions and dimensions to achieve super-foldability.

Herein, we propose a co-assembly strategy to fabricate hierarchical chiral mesostructures by combining a liquid crystalline block copolymer (LC-BCP) with a small molecular amphiphile containing chiral alanine or phenylalanine as a linker. Through a classic solvent-exchange process, chiral amphiphiles embedded within LC-BCP finely regulate the LC ordering effect and facilitate transfer and amplification of asymmetry. Consequently, various co-assembled structures with significant hierarchical chirality features are obtained through synergetic effects. Remarkably, subtle alterations to the side groups of amino acids in the amphiphiles effectively adjust the hierarchical morphology transition.

Through fusing CD lipids into the tumor cell membrane using a fusogenic liposome formulation, the cholesterol in the plasma membrane is reduced due to the specific host–guest interactions between CD lipid and cholesterol. As a result, tumor cells are stiffened, and the activation of lymphocytes (including NK and cytotoxic effector T cells) is improved when contacting the stiffened tumor cells, characterized by robust degranulation and effector cytokine production. Notably, this treatment has negligible influence on the infiltration and proliferation of lymphocytes in tumor tissues, confirming that the enhanced antitumor efficacy should result from activating a specific number of lymphocytes caused by direct regulation of the tumor cell stiffness.

The low membrane selectivity in most reported literature is largely due to the unavoidable non-selective defects during synthesis, leading to a mismatch between the well-defined pore structure of polycrystalline molecular sieve materials. This paper presents a novel approach for minimizing non-selective defects in metal–organic framework (MOF) membranes by a constricted crystal growth strategy in a confined environment. The in situ ZIF formation using the densely packed seeding array between the substrate and the pre-grown top ZIF layer yields a confined membrane interlayer, which is highly uniform with a tightly packed crystalline structure. Unlike uncontrolled crystal growth, we purposely regulate the interlayer membrane growth in the direction parallel to the substrate. A notable 99 % decrease in defects in the confined interlayer was achieved compared to the random-grown top layer, leading to a ~353 % increment in H 2 /N 2 selectivity over the non-confined reference MOF membrane.

Although significant progress has been achieved in epitaxial growth of graphene on SiC recently, the underlying nucleation mechanism remains elusive. Here, we present a theoretical study to elucidate graphene near-equilibrium nucleation on Si-terminated hexagonal-SiC(0001) surface. It is found that the ultra-large lattice mismatch between SiC(0001) surface and graphene and the highly localized electron distribution on SiC(0001) surface lead to a distinctive nucleation process: (i) Most of the magic carbon clusters on SiC(0001) show only C 1 symmetry and are mainly composed of pentagonal rings; (ii) Two possible nucleation pathways are revealed, i.e ., longitudinal and circular modes; (iii) Carbon clusters are more stable on flat terraces than near atomic step edges.

Here, a series of host–guest doped materials, using benzophenone as the host and quinone compounds as the guests, were constructed to investigate the effect of the triplet energy gap (Δ E T ) between the host and guest on triplet states population. The guest's triplet state is proposed to be a “triplet energy reservoir”, gathering the triplet excitons to emit RTP when Δ E T is large and returning triplet excitons to the host when Δ E T is small. By combining the results of steady-state and delayed emission spectra, time-resolved transient absorption spectra, and theoretical calculations, a bidirectional energy transfer process is proved, which are triplet-triplet energy transfer and reverse triplet-triplet energy transfer processes. The thermal equilibrium of these two energy transfer processes can be regulated by the Δ E T and temperature.

Comprehensive sequence-reactivity profiles revealed that loop-closing ligation preferentially yields hairpin structures with loop sequences UNNG, CNNG, and GNNA (where N represents A, C, G, or U) under competing conditions. In contrast, splinted ligation products tended to be GC rich. Notably, the overhang sequences that preferentially partition to loop-closing ligation significantly overlap with the most common biological tetraloops, whereas the overhangs favoring splinted ligation exhibit an inverse correlation with biological tetraloops. Applying these sequence rules enables the high-efficiency assembly of functional ribozymes from short RNAs without template inhibition.

However, the instability of enzymes and their sensitivity to cellular environments present significant challenges for the broad application of ELISA in living cells. In this work, we present a bioorthogonal (poly)catalysis-linked immunosorbent assay (BCLISA) designed for the detection of cell membrane antigens, which involves coupling bioorthogonal catalysts based on small molecules or polymers to antibodies. After screening, we opted for the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) as the core reaction system. The polymer-based catalysts exhibit enhanced reactivity at the same molecular concentration due to their multiple catalytic sites. Polytriazoles formed during the CuAAC reaction have the ability to chelate Cu(I), thereby promoting faster catalysis. By harnessing this autocatalytic feature, we successfully increased the signal amplification potential of BCLISA. Ultimately, this autocatalysis-integrated BCLISA technique was employed for antigen detection and imaging on both in vitro and living cell membranes.

In this study, we proposed proton precompensation strategy to suppress the deprotonation effect of the buried interface and improve the durability of the devices.

While electrochemical methods enhance safety and may avoid the use of noble metals, these processes suffer from low yields due to limited current density and/or low selectivity. Here, we design an electrothermal process to conduct aerobic oxidation of methane to methanol at room temperature using phosphotungstic acid (PTA) as a redox mediator. When electrochemically reduced, PTA activates methane with O 2 to produce methanol selectively. The optimum productivity reaches 29.45 with approximately 20.3 % overall electron yield. Under continuous operation, we achieved 19.90 catalytic activity, over 74.3 % methanol selectivity, and 10 hours durability.

The current density towards methanol production increased over 40 times compared with direct electrochemical processes.

The spin order in TMMC below approximately 55 K is demonstrated by the disorder-order transition observed in the temperature-dependent magnetic susceptibility. This finding is further corroborated by the negligible shift in the temperature- and field-dependent emission peaks, a consequence of magnetic saturation.

  @article{ , abstract = {Aqueous manganese ion batteries hold potential for stationary storage applications owing to their merits in cost, energy density, and environmental sustainability. However, the formidable challenge is the instability of metallic manganese (Mn) anodes in aqueous electrolytes due to severe hydrogen evolution reaction (HER), which is more serious than the commonly studied Zn metal anodes. Moreover, the mechanism of HER side reactions has remained unclear. Herein, we design a series of Mn−P alloying anodes by precisely regulating their energy band structures to mitigate the HER issue. It is found that the serious HER primarily originates from the spontaneous Mn-H 2 O reaction driven by the excessively high HOMO energy level of Mn, rather than electrocatalytic water splitting. Owing to a reduced HOMO energy level and enhanced electron escape work function, the MnP anode achieves an evidently enhanced cycle durability (over 1000 hours at a high current density of 5 mA cm −2 ). The MnP||AgVO full cell with an N/P ratio of 4 exhibits better rate capability and extended cycle life (7000 cycles) with minimal capacity degradation than the cell using metallic Mn anode (less than 100 cycles).

The EDM capitalizes on APE1-triggered activation of DNAzyme (Dz) and its autonomous cleavage of substrates to achieve nonlinear signal amplification. Using EDM, we demonstrate a strong correlation between APE1 activity in EVs and that of their parental cancer cells.

In contrast to traditional chemical reaction cycles that exploit molecularly dissolved building blocks at thermodynamic equilibrium, we show that fiber structures derived from reactive naphthalene diimide (NDI) building blocks can be used as resting states to form far-from-equilibrium conductive hydrogels after the addition of chemical fuels. Upon fueling the NDI-derived fibers, a dual-component activation and deactivation pathway is deduced by kinetic analysis and is absent when using a molecularly dissolved resting state.

The resulting natural polyphenol-reinforced ion-selective (NPRIS24) separators exhibit rapid Li ion transport and high soluble intermediates inhibition capability with an ultralow shuttle rate of 0.67 % for Li 2 S 4 , 0.19 % for Li 2 S 6 and 0.10 % for Li 2 S 8 . This superior ion-selectivity arises from the high electronegativity and strong lithiophilic nature of the phenolic compounds.

Understanding the correlation between crystal structure variation and photoluminescence (PL) quenching is significant to achieve anti-thermal quenching (anti-TQ) phosphors. Herein, we unveil a universal principle governing switchable TQ and anti-TQ behaviors in zero-dimensional (0D) organic–inorganic hybrid manganese bromides. We observed an abnormal anti-TQ phenomenon when phosphor is excited in the valley of PL excitation (PLE) spectrum (indirect excitation) while TQ phenomenon is observed when excited in the peak and shoulder positions of PLE. Our findings demonstrate that PL intensity is influenced by two variable parameters: the effective Mn-ligand distance and the shortest Mn−Mn distance. These excitation-dependent TQ and anti-TQ behaviors originate from the relative changes in these distances, which modulate the competition between radiative and nonradiative recombination rates, as evidenced at the molecular level by molecular dynamics simulation. X-ray activated radioluminescence (RL) also exhibits anti-TQ behavior, which is analogous to the indirect excitation of PL evolution when excited at PLE valley. These insights bridge the gap between PL and RL properties in 0D manganese halides and offer potential avenues for developing advanced anti-TQ phosphors, efficient LEDs, and high-performance scintillators.}, archive = {J_ANGEW}, author = {Ye Wu and Yiyuan Zhu and Ashour A.

Here, we show that modulating the electronic band structure of two-dimensional black phosphorus (BP) is possible via the electronic effects of organic functional groups covalently modified on its surface. Organic functional group can either donate or withdraw charge density from BP surface, which will alter the bonding/anti-binding orbitals occupancy and thus shift the band-edge positions of functionalized BP downward/upward. Therefore, the valence-band maxima and the conduction-band minima of functionalized BP can be continuously tuned by changing the binding group with different Hammett parameters. Finally, unexpectedly high hydrogen evolution reaction rates under visible light are achieved using functionalized BP heterojunctions as photocatalysts.

Using synthetic models of oxygenated tyrosinase enzymes ligated exclusively by monodentate imidazoles, we find that deprotonation of the μ 2 -η 2 :η 2 -peroxidodicopper(II) species triggers redox isomerization to an imidazol ate -ligated bis(μ 2 -oxido)dicopper(III) species. Formal two-electron oxidation to Cu(III) remains biologically unprecedented, yet is effected readily by addition of base. Spectrophotometric titrations by UV/Visible/near-IR and copper K-edge X-ray absorption spectroscopies are interpreted most simply as two cooperative, 2H + transformations in which the peroxide O−O is cleaved in the first step. Elaboration from simple imidazoles to a protected histidine extends this isomerization into an amino acid environment. The role of phenolate as a base suggests this four-electron reduction of O 2 is energetically viable in a biological context and requires only two copper centers, which act as two-electron shuttles when imidazole deprotonation assists.

  @article{ , abstract = {Hard carbon (HC) materials are promising anodes for sodium-ion batteries (SIBs) owing to low cost, high specific capacity and low working potential. However, the poor compatibility of the electrolyte with HC leads to low initial coulombic efficiency (ICE) and sluggish Na + transport kinetics. Here, we propose an electrolyte reconfiguration strategy based on the hard and soft acid and base (HSAB) theory by introducing methyltriphenylphosphonium bromide (MTPPB). MTPPB can realize a spontaneous cross-coordination solvation structure with NaPF 6 by selective affinity, synchronously optimizing the interfacial chemistry and sodium storage process. The advantages of the chemical π–π bridging of MTPP + -HC and interaction of MTPP + -PF 6 − contribute to preferential and oriented reduction of PF 6 − , forming a low-resistance supramolecular SEI. Additionally, Na + -Br − coordination weakens the Na + -solvent interactions, facilitating Na + de-solvation kinetics. Consequently, the HC||Na cell achieves a superior ICE of 96.6 %, desirable rate capability under 25 °C and invisible capacity decay after 500 cycles at 1 C under −20 °C. The Na 4 Fe 3 (PO 4 ) 2 P 2 O 7 ||HC pouch battery displays a high ICE of 90.3 % and a 15 % increment of energy density under 25 °C.

  @article{ , abstract = {Organic-inorganic hybrid perovskite materials, such as formamidinium lead iodide (FAPbI 3 ), are among the most promising emerging photovoltaic materials. However, the spontaneous phase transition from the photoactive perovskite phase to an inactive non-perovskite phase complicates the application of FAPbI 3 in solar cells. To remedy this, alkali metal cations, most often Cs + , Rb + or K + , are included during perovskite synthesis to stabilize the photoactive phase. The atomic-level mechanisms of stabilization are complex. While Cs + dopes directly into the perovskite lattice, Rb + does not, but instead forms an additional non-perovskite phase, and the mechanism by which Rb confers increased stability remains unclear. Here, we use 1 H− 87 Rb double resonance NMR experiments to show that FA + incorporates into the Rb-based non-perovskite phases (FA y Rb 1- y Pb 2 Br 5 and δ-FA y Rb 1- y PbI 3 ) for both bromide and iodide perovskite formulations. This is demonstrated by changes in the 1 H and 87 Rb chemical shifts, 1 H− 87 Rb heteronuclear correlation spectra, and 87 Rb{ 1 H} REDOR spectra. Simulation of the REDOR dephasing curves suggests up to ~60 % FA + incorporation into the inorganic Rb-based phase for the bromide system. In light of these results, we hypothesize that the substitution of FA + into the non-perovskite phase may contribute to the greater stability conferred by Rb salts in the synthesis of FA-based perovskites.}, archive = {J_ANGEW}, author = {Ummugulsum Gunes and Michael A.

The freshly isolated material is a ca 60 : 40 mixture of triclinic (HS1) and tetragonal (HS2) high-spin polymorphs, which are structurally closely related. Both HS1 and HS2 undergo a high→low-spin transition on cooling at 230±10 K.

Powder diffraction, calorimetry and magnetic data show that multiple cycling about the spin-transition leads to slow enrichment of the HS1 and LS3 phases at the expense of HS2 and LS4.

To construct a model TRS, we first realized highly selective generation of three classical ROS ( 1 O 2 , HO⋅ and SO 4 ⋅ − ) by peroxymonosulfate activation in an electrochemical Fenton-like system, where three replaceable Fe-centered cathodes were rationally designed as electronic mediator.

It is found that increasing the distance between the N dopant and the Ir 1 site results in a different energy change for the reaction process compared to the dense doping models with only first and second-shell N species. The proposed stochastic doping models demonstrate statistically that increasing the N dopant in farther shells not only enhances the activity of Ir 1 but also maintains a high selectivity for propene, which is verified by experimental tests. The modulation of the d -band center of Ir 1 by stochastic N dopants effectively modifies the binding strength of reaction intermediates, thereby enabling the optimization of the potential energy surface of PDH.

The prepared metallopolymer possesses combined merits of outstanding mechanical and thermal stability, as well as a low glass transition temperature ( T g <−50 °C). Based on this metallopolymer, an advanced metal–organic coordination enhanced metallopolymer electrolyte (MPE) is developed for constructing high-performance solid-state lithium metal batteries (LMBs).

Moreover, dynamic metal–organic coordination bonds endow the MPE with re-processability and self-healing, enabling it to accommodate electrode volume changes and maintain good interfacial contact. Consequently, the MPE achieves a competitive ionic conductivity of 0.712 mS cm −1 (25 °C), a high t Li+ (0.625), and a wide electrochemical stability window (>5.0 V).

For the designed 2,2′,2′′-(2,4,6-trihydroxybenzene-1,3,5-triyl) tris (1H-naphtho[2,3-d]imidazole-4,9-dione) (TPNQ) molecule, the intramolecular HBs (O−H⋅⋅⋅N and N−H⋅⋅⋅O) reduce the charge density of active sites and alter the charge distribution on the molecular skeleton. As a result, TPNQ shows significantly reduced solubility in both ether- and ester-based solvents. In situ measurements and theoretical calculations indicate that the O−H⋅⋅⋅N dominated HB interaction strengthening during the discharging process, which can continuously suppress dissolution.

AzoM enables optical control of endogenously and heterologously expressed TRPM8 channels with UV and blue light which is demonstrated by performing patch-clamp experiments. Moreover, AzoM facilitates the reliable determination of activation, inactivation, and deactivation kinetics thereby providing further insights into the channel gating. Using AzoM, the specific roles of individual amino acids for AzoM or PIP 2 binding and for sensitization by PIP 2 can be elucidated. Altogether, AzoM represents as a high-precision pharmaceutical tool for reversible control of TRPM8 channel function that enhances our biophysical understanding of TRPM8 channels and holds the potential to support the development of novel pharmaceuticals.}, archive = {J_ANGEW}, author = {Jasmin Becker and Clara S.

  @article{ , abstract = {An established concept to create radical intermediates is photoexcitation of a catalyst to a higher energy intermediate, subsequently leading to a photoinduced electron transfer (PET) with a reaction partner. The known concept of consecutive photoinduced electron transfer (con-PET) leads to catalytically active species even higher in energy by the uptake of two photons. Generally speaking, increased photon uptake leads to a more potent reductant. Here, we report the concept of multi-photoinduced electron transfer catalysis (>2 photons), termed multi-PET, which is enabled by photoinduced one-electron reductions of an organic dye. Further irradiation of the doubly reduced species leads to a photoexcited dianionic super-reductant, which is more potent than Li metal – one of the strongest chemical reductants known. This multi-photon process which is enabled by 390 nm LEDs allows the cleavage of strong carbon-fluorine bonds and reduction of other halides even in very electron-rich substrates. The resulting radicals are quenched by hydrogen atoms or engaged in carbon-carbon and carbon-phosphorus bond formations, highlighting the utility of multi-PET for organic chemistry. In addition, multi-PET enabled Birch-type reductions.

It is found that the dimethylglyoxime-urethane moiety has dynamic nature, endowing the material with open-loop upcycling ability. By removing the dimethylglyoxime segment via a simple sublimation process, the material structure is transformed from linear molecular into crosslinked network. More interestingly, the transformation is reversible, and the regenerated crosslinked network can be transformed back to linear molecule by returning the removed dimethylglyoxime segment to the material, which means the upcycled product can be recycled again after its service life.

Guanidinium stapling was readily achieved on solid support, utilizing two orthogonally protected lysine or unatural α-amino acid residues with an amino function. This method allows for easy modulation of the nature and size of the staple as well as helix propensity. Evaluating a set of guanidinium-stapled peptides for their interaction with different protein targets identified several binders with increased target affinity. X-ray structure determination of four complexes revealed that all stapled peptides adopt a helical conformation upon protein binding. Notably, the disubstituted guanidinium generally exhibits a distinct cis / trans conformation and, in one instance, retains a conserved hydrogen bond with the protein surface.

Compared with single metal site, the Au−V o −Ti interface sites exhibit the lower CO 2 adsorption energy and decrease the energy barrier of the *CO 2 hydrogenation step from 1.05 to 0.77 eV via Au−C and Ti−O dual-site bonding. The adsorbed CO 2 on the photocatalyst reduces the energy barrier of *CH 4 dissociation to *CH 3 from 2.13 to 1.59 eV, contributing to CH 4 oxidation. Additionally, in situ Fourier-transform infrared spectroscopy unveils the Au site facilitates ethane production by engaging in *CH 3 −Au interaction and accelerating CH 3 −CH 3 coupling. Thus, the photocatalyst demonstrates a high C 2 H 6 evolution rate of 2.60 mmol g −1 h −1 for OCM using CO 2 as the soft oxidant, surpassing most of previously reported photocatalysts regardless of OCM and nonoxidative coupling of methane. This work highlights the importance of soft oxidants for improving oxidation reaction efficiency and provides atomic scale insight into the design of photocatalysts for CH 4 conversion.}, archive = {J_ANGEW}, author = {Mingyu Wu and Juncheng Zhu and Yang Wu and Siying Liu and Kai Zheng and Shumin Wang and Bangwang Li and Jing Li and Chengyuan Liu and Jun Hu and Junfa Zhu and Yang Pan and Yongfu Sun and Yi Xie}, doi = {10.1002/anie.202414814}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {5}, pages = {e202414814}, shortjournal = {Angew.

  @article{ , abstract = {The “Magic Methyl” effect has received tremendous interest in medicinal chemistry due to the significant pharmacological and physical modification of properties that have been observed upon introducing a methyl group, especially, a stereogenic methyl group into potential chiral drug candidates. The prevalence of stereogenic β-methyl ketone structural motifs in bioactive compounds and natural products has long motivated the development of enantioselective strategies toward their synthesis. Herein, we have rationally designed a Rh-catalyzed asymmetric monohydrogenation of readily-available β′-methylene conjugated enones with high efficiency and remarkable site-selectivity and enantioselectivity control for the practical construction of enantioenriched β′-methyl unsaturated enones that are difficult to access by other methods. Control experiments revealed that the conjugated C=C bond in β′-methylene conjugated enones plays a significant role in enhancing the reactivity of monohydrogenation. This methodology is applicable for the preparation of chiral β,β′-dimethyl ketones through consecutive double asymmetric hydrogenation of β,β′-dimethylene ketones. Detailed mechanistic investigation and DFT studies further provided strong support for a unique processive catalysis pathway for double asymmetric hydrogenation.

However, the therapeutic efficacy of PROTACs is restricted due to their hydrophobicity, poor cell permeability and insufficient tumor-targeting ability. Herein, we develop the self-assembled peptide-derived PROTAC nanoparticles (PT-NPs) for precise and durable programmed death-ligand 1 (PD−L1) degradation in targeted tumors. The PT-NPs with an average size of 211.8 nm are formed through the self-assembly of amphiphilic peptide-derived PROTAC (CLQKTPKQC-FF-ALAPYIP), comprising a PD−L1-targeting ‘CLQKTPKQC’, self-assembling linker ‘FF’ and E3 ligase recruiting ‘ALAPYIP’. Particularly, PT-NPs strongly bind to tumor cell surface PD−L1 to form PD−L1/PT-NPs complex, then internalized through receptor-mediated endocytosis and degraded in lysosomes. Second, free PROTACs released from PT-NPs to the cytoplasm further induce the durable proteolysis of cytoplasmic PD−L1 via the ubiquitin-proteasome system. In colon tumor models, intravenously injected PT-NPs accumulate significantly at targeted tumor tissues through nanoparticle-derived passive and active targeting. At the targeted tumor tissues, PT-NPs promote durable PD−L1 degradation and ultimately trigger a substantial antitumor immune response.

Electron microscopy confirmed successful exfoliation of bulk FGT to nanosheets as thin as 6 nm. The ferromagnetic ordering temperature for the nanosheets gradually decreased with the increase in the centrifugation speed used to isolate the 2D material. These nanosheets were resuspended in NMP and treated with an organic acceptor, 7,7,8,8-tetracyano-quinodimethane (TCNQ), which led to precipitation of FGT-TCNQ composite. The formation of the composite material is accompanied by charge transfer from the FGT nanosheets to TCNQ molecules, generating TCNQ⋅ − radical anions, as revealed by experimental vibrational spectra and supported by first principles calculations. Remarkably, a substantial increase in magnetic anisotropy was observed, as manifested by the increase in the coercive field from nearly zero in bulk FGT to 1.0 kOe in the exfoliated nanosheets and then to 5.4 kOe in the FGT-TCNQ composite.

While the intrinsic monolayer nature of SAMs provides unique advantages, it also makes them highly sensitive to external pressure, posing a significant challenge for long-term device stability. At present, the stability issue of SAM-based PVSCs is gradually attracting attention. In this minireview, we discuss the fundamental stability issues arising from the structural characteristics, operating mechanisms, and roles of SAMs, and highlight representative works on improving their stability. We identify the buried interface stability concerns in three key aspects: 1) SAM/MO interface, 2) SAM inner layer, and 3) SAM/perovskite interface, corresponding to the anchoring group, linker group, and terminal group in the SAMs, respectively. Finally, we have proposed potential strategies for achieving excellent stability in SAM-based buried interfaces, particularly for large-scale and flexible applications. We believe this review will deepen understanding of the relationship between SAM structure and their device performance, thereby facilitating the design of novel SAMs and advancing their eventual commercialization in high-efficiency and stable inverted PVSCs.}, archive = {J_ANGEW}, author = {Xinyu Yu and Xianglang Sun and Zonglong Zhu and Zhong'an Li}, doi = {10.1002/anie.202419608}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {4}, pages = {e202419608}, shortjournal = {Angew.

Most notably, its Ag−Br coordination bonds show a zipper-like dynamic switching behavior from the ‘locked’ to ‘unlocked’ state, namely, reconstruction of chemical bonds. Coupling with the dynamic ordering of organic cations, this bond-switching transition makes a contribution to switchable polarization of 1 .

Highly uniform nanocapsules (NCs) could be prepared without adding extra catalysts at room temperature in just 4.5 h at a yield of 86 %. The NCs have tunable average diameters of 114–565 nm and shell thicknesses of 12–63 nm, depending on the monomer and surfactant types/concentrations. Their BET-specific surface areas are up to 139.0 m 2 /g, mainly contributed by narrowly-distributed mesopores at ~5.0 nm and micropores at 1.4 nm at a volume ratio ( V 1.4 /V 5.0 ) of 1.68. The surfactant plays the role of a catalyst during the reaction and interestingly, it also regulates the formation of mesopores and their sizes. Both theoretical and experimental studies confirm that the reaction has been accelerated by two orders of magnitude at the microdroplet interface, compared to that without emulsification. The resulting NCs could be well dispersed in water for at least six weeks with little size-distribution change, and they have been demonstrated to be highly efficient nanocatalysts in application of water-based hydrogen evolution, reaching a stable hydrogen production rate at 10.2 mmol ⋅ g −1 ⋅ h −1 for 6 hours.

Here, we have synthesized ZnO/ZrO 2 catalysts supported on tetragonal ZrO 2 (ZnO/ZrO 2 -t) and monoclinic ZrO 2 (ZnO/ZrO 2 -m), which resulted in the formation of different ZnO x species, consisting of sub-nanometer ZnO moieties and large-sized ZnO particles, respectively. ZnO/ZrO 2 -t exhibited a higher methanol selectivity (81 vs. 39 %) and methanol yield (1.25 vs. 0.67 mmol g −1 h −1 ) compared with ZnO/ZrO 2 -m. The difference in performance was attributed to the redox state and degree of dispersion of Zn, based on spectroscopy and microscopy results. ZnO/ZrO 2 -t had a high density of ZnO x -ZrO y sites, which favored the formation of active HCOO* species and enhanced the yield and selectivity of methanol along the formate pathway. Such ZnO clusters were further dispersed on ZrO 2 -t during catalysis, while larger ZnO particles on ZnO/ZrO 2 -m remained stable throughout the reaction.

While dimethyl sulfoxide (DMSO) is traditionally used to manage this process, its removal from the films is problematic. In this work, methyl phenyl sulfoxide (MPSO) was employed instead of DMSO to slow the crystallization rate, as MPSO is more easily removed from the perovskite structure. The electron delocalization associated with the benzene ring in MPSO decreases the electron density around the oxygen atom in the sulfoxide group, thus reducing its interaction with PbI 2 . This strategy not only sustains the formation of a crystallization-slowing intermediate phase but also simplifies the elimination of the additive.

In this study, we developed an organic photocatalytic system using covalent triazine/heptazine-based frameworks (CTF-TB/CHF-TB) to enable the B–V oxidation reaction under mild conditions through a cascade reaction pathway. Experimental data and theoretical calculations showed that heptazine/triazine units can “chelate” and decompose the in situ generated H 2 O 2 into hydroxyl radicals (⋅OH). Compared to conventional methods that primarily involve metal-activated benzaldehyde at elevated temperatures (e.g., 60 °C), the ⋅OH generated in our study can readily cleave the C−H bond of benzaldehyde, forming an active intermediate that drives subsequent sequential processes: O 2 →H 2 O 2 →⋅OH→Ph-CO⋅→Ph-COOO⋅.

Consequently, a significant challenge persists in achieving a covalent network that combines high strength, stiffness, toughness, and fast recovery performance. To address this challenge, we propose a novel sacrificial structure termed “sacrificial conformation.” In this approach, β-cyclodextrin is covalently embedded into the network skeleton as the sacrificial conformation element. Compared to traditional covalent networks (LCN), well-designed cyclodextrin-embedded covalent network (CCN) exhibit a 100-fold increase in Young's modulus and a 60-fold increase in toughness.

  @article{ , abstract = {Interhalogen-involved aqueous Zn||halogen batteries (AZHBs) are latent high-energy systems for grid-level energy storage, yet usually suffer from poor high-rate endurability caused by the formation of “dead species”. Herein, via an electrochemically-densified cathode-interface-reaction layer (CIRL), Zn||I−Br batteries involving interhalogen reactions between the I 2 cathode and Br − from the electrolytes are initially achieved with excellent high-rate endurability. Different from that in diluted electrolytes, the CIRL formed in Br − -concentrated electrolyte is denser and water-lean, which enables halogen species conversion with a more rapid charge transfer and lower activation energy. More importantly, the CIRL robustly affords a decent I 2 conservation by accelerated conversion kinetics and limited species diffusion, thereby endowing the Zn||I−Br batteries with an ultralong high-rate lifespan. The electrochemical mechanism is sufficiently verified by multiple spectral characterizations. Consequently, Zn||I−Br batteries in Br − -concentrated (20 m) electrolytes exhibit an overwhelming rate capability and lifespan to those in Br − -diluted (2 m) electrolytes. Typically, when cycled at a large current density of 10 A g −1 , an ultralong lifespan of over 25,000 cycles is achieved with a high retention of 98.3 %.

The amalgamation of advantages confers TBT-V-F-based OPDs with lower nonradiative energy loss, improved charge transport, decreased energetic disorder, and reduced trap density. Consequently, the corresponding self-powered OPDs exhibit a 40-fold decrease in J d , a remarkable increase in detectivity ( D * sh ), faster response time, and superior thermal stability compared to TBT-V-Cl-based OPDs. Further interfacial optimization results in an ultra-low J d of 7.30×10 -12 A cm −2 with D * sh over 10 13 Jones in 320–920 nm wavelength and a climax of 2.2×10 14 Jones at 800 nm for the TBT-V-F-based OPDs, representing one of the best results reported to date.

Of critical challenges are the anomalously high storage capacities beyond their theoretical values and the fast ion diffusivity that cannot be satisfactorily comprehended in the theory of crystal lattice. Herein, for the first time we decode t 2g electron occupation-regulated dual-redox Li-storage mechanism as the true origin of extra capacity in POMs electrodes. The lattice and electronic transition of active centers and reaction intermediates were systematically decoupled through density functional theory (DFT) and a suite of structural spectroscopic investigations, such as X-ray absorption near-edge spectroscopy (XANES), soft X-ray absorption spectroscopy (sXAS) and 7 Li solid-state nuclear magnetic resonance (NMR). Enhanced V-t 2g orbital occupation by Li coordination significantly triggers the Hubbard gap closure and reversible Li deposition/dissolution at surface region. Conjugated V−O-Li configuration at interlayers endow Li + ion pathways along pore walls as the dominant contribution to the low migration barrier and fast diffusivity.

The final CeO x /Mn 3 O 4 nanozyme demonstrates potent catalase-like (CAT-like) and superoxide dismutase-like (SOD-like) activities, excelling in both chemical settings and cellular environments with high reactive oxygen species (ROS) levels.

  @article{ , abstract = {Selective CO 2 photoreduction into high-energy-density and high-value-added C 2 products is an ideal strategy to achieve carbon neutrality and energy shortage, but it is still highly challenging due to the large energy barrier of the C−C coupling step and severe exciton annihilation in photocatalysts. Herein, strong and localized charge polarization is successfully induced on the surface of melon-based organic semiconductors by creating dual active sites with a large charge asymmetry. Confirmed by multiscale characterization and theoretical simulations, such asymmetric charge distribution, originated from the oxygen dopants and nitrogen vacancies over melon-based organic semiconductors, reduces exciton binding energy and boosts exciton dissociation. The as-formed charge polarization sites not only donate electrons to CO 2 molecules but also accelerate the coupling of asymmetric *CO*CO intermediates for CO 2 photoreduction into ethanol by lowering the energy barrier of this process. Consequently, an exceptionally high selectivity of up to 97 % for C 2 H 5 OH and C 2 H 5 OH yield of 0.80 mmol g −1 h −1 have been achieved on this dual active sites organic semiconductor.

For this purpose, we present a de novo-designed ligand-responsive artificial protein–protein communication (LIRAC) by redefining the connection between TFs and non-interacting CRISPR/Cas enzymes. By rationally designing a chimeric DNA adaptor and precisely regulating its binding affinities to both proteins, LIRAC immediately transduces target-induced TF allostery into rapid CRISPR/Cas enzyme activation within a homogeneous system. Consequently, LIRAC obviates the need for RNA/protein biosynthesis inherent to conventional TXTL-based cell-free systems, substantially reducing reaction complexity and time (from hours to 10 minutes) with improved sensitivity and tunable dynamic range. Moreover, LIRAC exhibits excellent versatility and programmability for rapidly and sensitively detecting diverse contaminants, including antibiotics, heavy metal ions, and preservatives. It also enables the creation of a multi-protein communication-based tristate logic for the intelligent detection of multiple contaminants.

  @article{ , abstract = {Perchlorate, initially regarded as a weakly coordinating counterion rather than a reactive oxidizing reagent due to its kinetic stability, has garnered attention for its potential in microbial systems. Under anaerobic conditions, microbes utilize perchlorate as a terminal oxidant for methane oxidation, involving two distinct stages: extraction and release of oxidizing ability. This two-phase activation process necessitates the collaborative action of multiple enzymes, a phenomenon not extensively explored in artificial systems. To address this issue, a dinuclear Fe-NHC (N-heterocyclic carbene) complex 1 was designed to enable the two-phase activation of perchlorate. Initially, complex 1 extracts the oxidative potential of perchlorate, leading to the formation of Fe(III)-O−Fe(III) complex 2 as the oxidation product. Subsequently, the extracted oxidative potential can be released by photolyzing a mixture of complex 2 and 9,10-dihydroanthracene.

We reveal that the formed biofilm microstructure provides an independent anaerobic microenvironment that simultaneously supports cellular viability, maintains hydrogenase activity, and preserves the functional stability of CdS, giving rise to the efficient plastic-to-hydrogen conversion efficiency as high as 3751 μmol H 2 g-1 PLA. Besides, by genetically engineering transmembrane pili conduit and incorporating conductive nanomaterials to strengthen the electron transfer across cellular interface and biofilm matrices, we show that the conversion efficiency is further enhanced to 5862 μmol H 2 g-1 PLA. Significantly, we exhibit that a long-term sustainable plastic-to-hydrogen conversion of 63 d could be achieved by periodically replenishing PLA wastes.

  @article{ , abstract = {Solid-electrolyte interphase (SEI) plays a decisive role in building reliable Li metal batteries. However, the scarcity of anions in Helmholtz layer (HL) caused by electrostatic repulsion usually leads to the inferior SEI derived from solvents, resulting in dendrites and ‘dead’ Li. Therefore, regulating the distribution of anions in electric double layer (EDL) and continuously introducing more anions into HL to tailor anions-derived SEI is crucial for achieving stable Li plating/stripping. Herein, by jointly utilizing the controlled defects of reduced graphene oxide (rGO) and the oriented dipoles of ferroelectric BaTiO 3 (BTO), the rGO-BTO composite layer sustainedly brings more TFSI − and NO 3 − into anion-defecient HL, promoting favorable decomposition of anions and guiding the generation of robust and fast-Li + -transport SEI containing more inorganics LiF and Li 3 N species. Thus, the resulting Li deposit shows smooth and dense morphologies without dendrites, leading to high average Coulombic efficiency.

Various characterization methods, particularly the multiple one- and two-dimensional magic-angle spinning (MAS) NMR techniques, were performed to track the alkali-treatment processes. For the sample with a more uniform spatial Al distribution, more tetrahedral Al sites would fall off and migrate around the Si-OH in zeolite as Al(OH) 4 − . Those re-deposited Al(OH) 4 − sites were easily transformed into NMR-invisible Al sites during the calcination process, which contributed negligibly to both Brönsted and Lewis acidities, thus being referred to “acid-free” Al species.

Inspired by nature, here we design a supramolecular approach to equip living cells with these capacities, enabling recyclable, efficient cascade reactions. Our two-step “plug-and-play” methodology begins by coating Escherichia coli cells with guest-containing polymers (SupraBAC) via supramolecular charge interactions, followed by the introduction of β-cyclodextrin-functionalized host enzymes through host-guest chemistry, creating a robust cell-enzyme complex. This supramolecular coating not only protects cells from various stresses, such as UV radiation, heat, and organic solvents, but also facilitates the overexpression of intracellular enzymes and the attachment of extracellular enzymes within and on SupraBAC. This combination results in efficient multienzyme cascade synthesis, enabling two- and three-step reactions in one pot.

  @article{ , abstract = {The research on electrocatalytic carbon dioxide reduction (ECR) catalysts using renewable energy is particularly crucial in energy conversion studies, especially for viable hydrocarbon production. This study employs density functional theory calculations to screen a series of non-radioactive lanthanide two-dimensional metal–organic frameworks (MOFs) for product selectivity in ECR. Based on theoretical screening, our focus is on a lutetium (Lu)-based conducting MOF (Lu-HHTP), which exhibits a Faradaic efficiency of approximately 77 % for methane (CH 4 ) production and maintains a stable current density of −280 mA/cm 2 at −1.1 V vs. RHE. In situ electrochemical experiments and material characterization demonstrate that the Lu sites possess high coordination stability and structural recoverability during catalytic CO 2 reduction, attributed to the overlap between Lu′s f-orbitals and the π*-orbitals of the ligand O, and the formation of back bonding orbitals between the f-orbitals of Lu and the π* orbitals of CO contribute increasing CH 4 selectivity and lowering the potential.

  @article{ , abstract = {Covalent organic frameworks (COFs) have garnered growing interest in the field of biomedicine; however, their application in sonodynamic therapy remains underexplored due to limited understanding of their intrinsic activity and structure–property relationships. Here, we present a pore wall chemistry modulation strategy for empowering sonodynamic activity to two-dimensional (2D) COF heterojunctions through in situ growth of COFs on bismuth oxycarbonate nanosheets (B NSs). Compared to the negligible sonodynamic effects observed in the pristine B NSs, the 2D heterojunction with vinyl-decorated COF pore walls demonstrates a 3.6-fold enhancement in sonocatalytic singlet oxygen generation. This performance also significantly outperforms that of isoreticular COFs functionalized with methoxy or non-substituted groups. Mechanistic studies reveal that the vinyl groups in the B@COF (BC) heterojunction facilitate the separation and transfer of charge carriers while also enhancing the adsorption of oxygen molecules. Furthermore, peroxymonosulfate (PMS) loading into the porous COFs boosts the therapeutic efficacy of antitumor nanotherapy via sonocatalytic dual oxidative species generation. These findings underscore the critical role of pore wall chemistry in modulating the sonocatalytic properties of COFs, and advance the development of COF-based sonosensitizers for pro-oxidative applications.}, archive = {J_ANGEW}, author = {Ruohui Wu and Mengying Hua and Yanjia Lu and Liang Chen and Yu Chen and Zhongqian Hu}, doi = {10.1002/anie.202416461}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {4}, pages = {e202416461}, shortjournal = {Angew.

  @article{ , abstract = {Pyroptosis, an inflammatory modality of programmed cell death associated with the immune response, can be initiated by bioactive ions and reactive oxygen species (ROS). However, bioactive ion-induced pyroptosis lacks specificity, and further exploration of other ions that can induce pyroptosis in cancer cells is needed. Sonocatalytic therapy (SCT) holds promise due to its exceptional penetration depth; however, the rapid recombination of electron-hole (e − -h + ) pairs and the complex tumor microenvironment (TME) impede its broader application. Herein, we discovered that antimony (Sb)-based nanomaterials induced pyroptosis in cancer cells. Therefore, Schottky heterojunctions containing Sb component (Sb 2 Se 3 @Pt) were effectively designed and constructed via in situ growth of platinum (Pt) nanoparticles (NPs) on Sb 2 Se 3 semiconductor with narrow band gaps, which were utilized as US-heightened pyroptosis initiators to induce highly effective pyroptosis in cancer cells to boost SCT-immunotherapy. Under US irradiation, excited electrons were transferred from Sb 2 Se 3 nanorods (NRs) to the co-catalyst Pt via Schottky junctions, and band bending effectively prevented electron backflow and achieved efficient ROS generation. Moreover, the pores oxidized and depleted the overexpressed GSH in the TME, potentially amplifying ROS generation. The biological effects of the Sb 2 Se 3 @Pt nanoheterojunction itself combined with the sonocatalytic amplification of oxidative stress significantly induced Caspase-1/GSDMD-dependent pyroptosis in cancer cells. Therefore, SCT treatment with Sb 2 Se 3 @Pt not only effectively restrained tumor proliferation but also induced potent immune memory responses and suppressed tumor recurrence. Furthermore, the integration of this innovative strategy with immune checkpoint blockade (ICB) treatment elicited a systemic immune response, effectively augmenting therapeutic effects and impeding the growth of abscopal tumors.

Towards this achievement, seed-initiated supramolecular polymerization has emerged as a powerful tool, as it prevents unlimited growth and enables size control of the assembly outcome. However, the potential application of the seeding method in the context of complex supramolecular systems is hitherto unclear. Herein we demonstrate that minute differences in molecular design in direct proximity to intermolecular recognition sites govern the molecular packing and in turn dictate the efficacy of seeded polymerization processes.

• (2025). Unprecedented photocatalytic hydrogen peroxide production via covalent triazine frameworks constructed from fused building blocks. ANGEW, 64(4), e202416350. (www)

  @article{ , abstract = {Covalent organic frameworks (COFs) have garnered attention for their potential in photocatalytic hydrogen peroxide (H 2 O 2 ) production. However, their photocatalytic efficiency is impeded by insufficient exciton dissociation and charge carrier transport. Constructing COFs with superior planarity is an effective way to enhance the π-conjugation degree and facilitate electron-hole separation. Nonetheless, the conventional linear linkers of COFs inevitably introduce torsional strain that disrupts coplanarity. Herein, we address this issue by introducing inherently coplanar triazine rings as linkers and fused building blocks as monomers to create covalent triazine frameworks (CTFs) with superior coplanarity. Both experimental and theoretical calculations confirm that CTFs constructed from fused building blocks significantly enhance the electron-hole separation efficiency and improve the photocatalytic performance, compared to the CTFs constructed with non-fused building blocks. The frontier molecular orbitals and electrostatic potentials (ESP) revealed that the oxygen reduction reaction (ORR) is preferentially facilitated by the triazine rings, with the water oxidation reaction (WOR) likely occurring at the thiophene-containing moiety. Remarkably, CTF-BTT achieved an exceptional H 2 O 2 production rate of 74956 μmol g −1 h −1 when employing 10 % benzyl alcohol (V/V) as a sacrificial agent in an O 2 -saturated atmosphere, surpassing existing photocatalysts by nearly an order of magnitude.

  @article{ , abstract = {Bismuth vanadate (BVO) ranks among the most promising photoanodes for photoelectrochemical (PEC) water splitting. Nonetheless, slow charge separation and transport, besides the sluggish water oxidation kinetics, are key barriers to its photoefficiency. Here, we present a co-doping strategy that significantly improves the charge separation performance of BVO photoanodes. We found that, under standard one sun illumination, the Fe−N co-doped BVO photoanode (Fe−N−BVO) by N-coordinated Fe precursor reaches a record photocurrent density of 7.01 mA cm −2 at 1.23 V vs RHE after modified a surface co-catalyst (FeNiOOH), and exhibits an outstanding stability. By contrast, much lower photocurrent density is obtained for the N-doped, Fe-doped and Fe/N-doped BVO photoanode with separated N and Fe precursors. The detailed experimental characterizations show that the high activity of the Fe−N co-doped BVO photoanode is attributed to the enhanced photo-induced bulk charge separation, as well as the accelerated surface water oxidation kinetics. XPS, EXAFS and DFT calculations clearly show that, instead of formation of deep trapping state in the individually doped BVO, the co-doping of Fe−N into BVO generates Fe-based electronic states just below the bottom of conduction band and N-derived states just above the top of valence band. Such modulations in electronic structure enable the efficient trap of the electrons and holes to enhance the separation of photo-induced carriers, but hinder the charge recombination originated from the deep trapping sites.}, archive = {J_ANGEW}, author = {Jie Yang and Chaoyuan Deng and Yu Lei and Mengyu Duan and Yisen Yang and Xiaoran Chen and Sipeng Yang and Jikun Li and Hua Sheng and Weiqun Shi and Chuncheng Chen and Jincai Zhao}, doi = {10.1002/anie.202416340}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {4}, pages = {e202416340}, shortjournal = {Angew.

The optimized Co−Ba/Y 2 O 3 catalyst achieves extremely high H 2 production rate of 138.3 mmolH 2 ⋅ g cat −1 ⋅ min −1 at very low temperature (500 °C, GHSV=840,000 mL ⋅ g −1 ⋅ h −1 ) and Co−Ba/Y 2 O 3 exhibits excellent durability during the 350 h test, which realizes the highest activity among all non-noble catalysts, and reaches or even exceeds numerous reported Ru-based catalysts. Both Y 2 O 3 and Co demonstrate positive interactions with Ba, which significantly facilitates the dispersion of Ba species at high temperatures (≥600 °C). Ba single atoms significantly enhance the charge density of Co and form additionally active Co−O−Ba−Y 2 O 3 interfacial sites, which alleviates hydrogen poisoning and decreases the reaction barrier of the N−H bond activation of *NH.

It has been confirmed that the hybrid thieno[2,3-b]thiophene unit of this asymmetric core governs the energy level, the surface wettability, and the defect passivation capability of the SAMs, while the substituent of core has a greater impact on the molecular dipole and device stability. The synergistic effects from thieno[2,3-b]thiophene and fluorine lead to the KF-derived iPSC demonstrating a certified power conversion efficiency (PCE) of 25.17 % and excellent operational stability.

By establishing a pyridinium library, the manipulation over the aggregation in solutions is investigated at the molecular level. Both theoretical calculations and physiochemical methods are used to characterize the aggregate's structure, and salient findings are as follows. First, the singly-reduced monoradicals simultaneously aggregate in a concentrated solution, which is driven by the solvation effect, orbital overlap and dispersion interaction. Second, the aggregation can be manipulated by the molecular engineering strategy and counteracted by introducing either electrostatic repulsive force or twisted geometry. Third, the monoradical's aggregation yields a decrease in the molecular singly occupied molecular orbital energy level and a linear scaling relationship with its thermodynamic potential. As a result, the increase in the concentration lowers the battery's voltage, which counteracts its effort to increase the battery's energy density. The anti-aggregation is proven effective in breaking the scaling relationship and accordingly, a molecular strategy to manipulate aggregate electrochemistry is developed.

  @article{ , abstract = {Copolymers with precise compositions and controlled sequences are great appealing for high-performance polymeric materials, but their synthesis is very challenging. In this study, tetrakis[tris(dimethylamino)phosphoranylidenamino] phosphonium chloride (P5Cl) and triethylboron (TEB) were chosen as the binary catalyst to synthesize both well-defined block and truly random poly(ester–carbonate) copolymers via the one-pot/one-step terpolymerization of epoxide/anhydride/CO 2 under metal-free conditions. The bulky nature of phosphazenium cation not only led to loose cation–anion pairs and enhanced the reactivity, but also provided the chain-end an appropriate protection and improved the controllability. In particular, P5Cl/TEB with a molar ratio of 1/0.5 showed an extraordinary chemoselectivity for ring-opening alternating copolymerization (ROAC) of cyclohexene oxide (CHO) and phthalic anhydride (PA) first and then ROAC of CHO/CO 2 . Thus, well-defined block polyester–polycarbonate copolymers were synthesized by CHO/PA/CO 2 terpolymerization. The chemoselectivity was easily tuned and the ROAC of CHO/PA and ROAC of CHO/CO 2 occurred simultaneously with P5Cl/TEB=1/2, producing truly random poly(ester–carbonate) copolymers from CHO/PA/CO 2 . In addition, this P5Cl/TEB catalyst and the strategy to regulate its chemoselectivity are versatile for various anhydrides, epoxides and initiators. Thus, poly(ester–carbonate) copolymers with varying sequences, compositions, and topologies are successfully synthesized, making it possible to compare their properties and to expand their applications.}, archive = {J_ANGEW}, author = {Yukun Ma and Zehao Wang and Lihang Jiang and Jinbo Zhang and Chuanli Ren and Xinhui Kou and Shaofeng Liu and Zhibo Li}, doi = {10.1002/anie.202416104}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {4}, pages = {e202416104}, shortjournal = {Angew.

The use of a specifically engineered dynamic helicene stator in a novel overcrowded-alkene second-generation molecular motor based on a fluorinated dibenzofluorene fragment allows for an unprecedented control over helicity inversion. This is achieved by the mechanical coupling of the rotation of the rotor to the helicene inversion of the stator half via a remote chirality transmission process. Thus, the unidirectional rotary motion generated upon irradiation is used to invert the dynamic stereochemistry of a helicene, leading to a 6-step cycle with eight intermediates. In this cycle, both alternation between P and M configurations of the helicene stator and dynamic thermal interconversion (paddling motion) can be achieved. In-depth computational and spectroscopic studies were performed to support the associated mechanism.

  @article{ , abstract = {The integrative implementation of multiple different components into metallosupramolecular self-assemblies requires sophisticated strategies to avoid the formation of statistical mixtures. Previously, the key focus was set on thermodynamically driven reactions of simple homoleptic into complex heteroleptic structures. Using Pd 2 L A 2 L B 2 -type coordination cages, we herein show that integrative self-sorting can be reversed by a change of solvent (from DMSO to MeCN) to favor narcissistic re-segregation into coexisting homoleptic species Pd 2 L A 4 and Pd 3 L B 6 . Full separation (“unsorting”) back to a mixture of the homoleptic precursors was finally achieved by selective precipitation of Pd 3 L B 6 with anionic guest G 1 from MeCN, keeping pure Pd 2 L A 4 in solution. When a mixture of homoleptic Pd 3 L B 6 and heteroleptic Pd 2 L A 2 L B 2 is exposed to a combination of two different di-anions ( G 1 and G 2 ) in DMSO, selective guest uptake gives rise to two defined coexisting host–guest complexes. A joint experimental and deep theoretical investigation via liquid-state integral equation theory of the reaction thermodynamics on a molecular level accompanied by solvent distribution analysis hints at solvent expulsion from Pd 2 L A 4 to favor the formation of Pd 2 L A 2 L B 2 in DMSO as the key entropic factor for determining the solvent-specific modulation of the cage conversion equilibrium.}, archive = {J_ANGEW}, author = {Kristina E.

The cascade methanol synthesis proceeds via CO 2 reduction to formate by electrocatalyst [Cp*Ir(bpy)Cl] + (Cp*=pentamethylcyclopentadienyl, bpy=2,2′-bipyridine), Fischer esterification of formate to isopropyl formate catalyzed by trifluoromethanesulfonic acid (HOTf), and thermal transfer hydrogenation of isopropyl formate to methanol facilitated by the organometallic catalyst (H-PNP)Ir(H) 3 (H-PNP=HN(C 2 H 4 P i Pr 2 ) 2 ).

  @article{ , abstract = {Organic solar cells (OSCs) processed with non-halogenated solvents usually suffer from excessive self-aggregation of small molecule acceptors (SMAs), severe phase separation and higher energy loss ( E loss ), leading to reduced open-circuit voltage ( V oc ) and power conversion efficiency (PCE). Regulating the intermolecular interaction to disperse the aggregation and further improve the molecular packing order of SMAs would be an effective strategy to solve this problem. Here, we designed and synthesized two SMAs L8-PhF and L8-PhMe by introducing different substituents (fluorine for L8-PhF and methyl for L8-PhMe) on the phenyl end group of the inner side chains of L8-Ph, and investigated the effect of the substituents on the intermolecular interaction of SMAs, E loss and performance of OSCs processed with non-halogenated solvents. Through single crystal analysis and theoretical calculations, it is found that compared with L8-PhF, which possesses strong and abundant intermolecular interactions but downgraded molecular packing order, L8-PhMe with the methyl substituent possesses more effective non-covalent interactions, which improves the tightness and order of molecular packing. When blending the SMAs with polymer donor PM6, the differences in intermolecular interactions of the SMAs influenced the film formation process and phase separation of the blend films. The L8-PhMe based blend film exhibits shorten film formation and more homogeneous phase separation than those of the L8-PhF and L8-Ph based ones. Especially, the OSCs based on L8-PhMe show reduced non-radiative energy loss and enhanced V oc than the devices based on the other two SMAs. Consequently, the L8-PhMe based device processed with o -xylene ( o -XY) and using 2PACz as the hole transport layer (HTL) shows an outstanding PCE of 19.27 %. This study highlights that the E loss of OSCs processed with non-halogenated solvents could be decreased through regulating the intermolecular interactions of SMAs by inner side chain modification, and also emphasize the importance of effectivity rather than intensity of non-covalent interactions introduced in SMAs on the molecular packing, morphology and PCE of OSCs.}, archive = {J_ANGEW}, author = {Xiangxi Wu and Yufei Gong and Xiaojun Li and Shucheng Qin and Haozhe He and Zekun Chen and Tongling Liang and Caixuan Wang and Dan Deng and Zhaozhao Bi and Wei Ma and Lei Meng and Yongfang Li}, doi = {10.1002/anie.202416016}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {4}, pages = {e202416016}, shortjournal = {Angew.

  @article{ , abstract = {The fabrication of high-performance microbial fuel cells requires the evaluation of the activity of electrochemically active bacteria. However, this is challenging because of the time-consuming nature of biofilm formation and the invasive nature of labeling.

This method involves investigating the “pure” linear Stark effect of endogenous CO in the silent region of biological samples, which allows for probing the intrinsic electric field in the outer-membrane cytochromes of live bacterial cells. We found that reduced outer-membrane cytochromes can generate an additional intrinsic electric field equivalent to an applied potential of +0.29 V. We also found that the higher the electrical activity of the cell, the larger the generated electric field. This was also reflected in the output current of the constructed microbial fuel cells. Raman spectroscopy was employed to facilitate the assessment of electrochemical activity at the single-cell level in highly-diluted bacterial samples. After analysis, inactive bacteria were ablated by laser heating, and 20 active cells were cultured for further testing.

  @article{ , abstract = {We report the first conductance measurements of [ n ]staffane (bicyclopentane) oligomers in single-molecule junctions. Our studies reveal two quantum transport characteristics unique to staffanes that emerge from their strained bicyclic structure. First, though staffanes are composed of weakly conjugated C−C σ -bonds, staffanes carry a shallower conductance decay value (β=0.84±0.02 n −1 ) than alkane chain analogs ( β =0.96±0.03 n −1 ) when measured with the scanning tunneling microscopy break junction (STM-BJ) technique. Staffanes are thus more conductive than other σ -bonded organic backbones reported in the literature on a per atom basis. Density functional theory (DFT) calculations suggest staffane backbones are more effective conduits for charge transport because their significant bicyclic ring strain destabilizes the HOMO-2 energy, aligning it more closely with the Fermi energy of gold electrodes as oligomer order increases. Second, the monostaffane is significantly lower conducting than expected. DFT calculations suggest that short monostaffanes sterically enforce insulating gauche interelectrode orientations over syn orientations; these steric effects are alleviated in longer staffanes. Moreover, we find that [2-5]staffane wires may accommodate axial mechanical strain by “rod-bending”. These findings show for the first time how bicyclic ring strain can enhance charge transmission in saturated molecular wires.

Conjugation primarily at tryptophan sites can be accessed by selective cleavage of modifications at other sidechains.

Here, we report a novel chemical synergic interaction strategy to mitigate the abovementioned issues in WBG perovskites. To achieve that, a small amount of cationic β-cyclodextrin, composed of multiple ammonium cations, chlorine ions and abundant hydroxyl functional groups, was introduced into WBG perovskites, which effectively stabilized the halide ions and homogenized the phase distribution, comprehensively passivated the crystallographic defects, as well as efficiently immobilized the Pb 2+ ions.

The nucleation implies hydrolysis of monomeric zirconium chloride complexes into zirconium-oxo species, and this process is promoted by H 2 O and inhibited by HCl, allowing to control crystal size by adjusting H 2 O/Zr and HCl/Zr ratios. The rate-determining step of crystal growth is represented by the condensation of monomeric and oligomeric zirconium-oxo species into clusters, or nodes, with the structure identical to that in secondary building units (SBU) of UiO-66 framework. The rapid crystallization in the absence of HCl leads to formation of defective secondary building units with missing zirconium atoms, providing a pathway to control the number of defects in UiO-66 crystals. Remarkably, we have shown that assembling of the metal nodes and linkers into the UiO-66 structure is not the rate-limiting step, and the degree of deprotonation of the linker has no direct effect on the crystallization kinetics or crystal size of product.}, archive = {J_ANGEW}, author = {Mikalai A.

The lead halide frameworks consist of 1D linear [PbCl] + chains as inorganic building units and benzoxadiazole/benzothiadiazole/ benzoselenadiazole-funtionalized dicarboxylates as linkers. The covalent bonding between the organic ligands with electron−withdrawing groups and the electron-rich lead halide units not only facilitate the charge separation, but also enhance structural robustness that is critical for photocatalysis. The D-A structured lead halides serve as highly efficient heterogeneous photooxidation catalysts, including aerobic oxidation of C(sp 3 )−H bonds, oxidative coupling of primary amines, oxidation of phenylboronic acids and selective oxidation of sulfides that are demonstrated in 30 examples. Importantly, these photooxidation reactions are able to be driven by natural sunlight and ambient air to afford quantitative yields.

The study of p-TIPS-DSB presented here offers a compelling case highlighting the relationship between the degree of dynamicity of functional units and TE behavior.

  @article{ , abstract = {Non-thermal plasma discharge produced in the wake of charged microdroplets is found to facilitate catalyst-free radical mediated hydrazine cross-coupling reactions without the use of external light source, heat, precious metal complex, or trapping agents. A plasma-microdroplet fusion platform is utilized for introduction of hydrazine reagent that undergoes homolytic cleavage forming radical intermediate species. The non-thermal plasma discharge that causes the cleavage originates from a chemically etched silica capillary. The coupling of the radical intermediates gives various products. Plasma-microdroplet fusion occurs online in a programmable reaction platform allowing direct process optimization and product validation via mass spectrometry. The platform is applied herein with a variety of hydrazine substrates, enabling i) self-coupling to form secondary amines with identical N-substitutions, ii) cross-coupling to afford secondary amine with different N-substituents, iii) cross-coupling followed by in situ dehydrogenation to give the corresponding aryl-aldimines with two unique N-substitutions, and iv) cascade heterocyclic carbazole derivatives formation. These unique reactions were made possible in the charged microdroplet environment through our ability to program conditions such as reagent concentration (i. e., flow rate), microdroplet reactivity (i. e., presence or absence of plasma), and reaction timescale (i. e., operational mode of the source). The selected program is implemented in a co-axial spray format, which is found to be advantageous over the conventional one-pot single emitter electrospray-based microdroplet reactions.}, archive = {J_ANGEW}, author = {Alexander J.

  @article{ , abstract = {Reprogrammable shape morphing is ubiquitous in living beings and highly crucial for them to move in normal situations, even to survive under dangerous conditions. There is increasing interest in using asymmetric hydrogel structures to understand and mimic living beings’ shape morphing upon an external trigger in a controlled way. However, these asymmetric or heterogeneous configurations cannot be further modified once the polymer hydrogels are prepared. Therefore, it is a great challenge to achieve reprogrammable shape morphing using the existing hydrogels. Inspired by marine amoebae, which transform into several different morphologies according to the various external salt concentrations, a new strategy is developed for salting hydrogels to reconfigure their anisotropy toward reprogrammable shape morphing. Polyampholyte hydrogels with equal stoichiometric COO − and N + (CH 3 ) 3 groups were first swollen in HCl/NaCl solution. After being then transferred into water, they first swollen again by water uptake driven by the osmotic pressure, and then were spontaneously deswollen due to increase in internal pH and dialysis of ions leading to deprotonation of COOH to COO − and regeneration of COO − /N + (CH 3 ) 3 electrostatic attraction.

The PMEI effect originates from the unique arrangement of isolated Pt atoms and HPW clusters on the CeO 2 support. Electrons are transferred from the ceria support to the electrophilic tungsten in HPW clusters, and subsequently, Pt atoms donate electrons to the now electron-deficient ceria. This phenomenon enhances the positive charge of Pt atoms, moderating O 2 activation and limiting lattice oxygen mobility compared to the conventional Pt 1 /CeO 2 catalyst.

The obtained Cu/ceria catalyst under H 2 environment (Cu/ceria-H 2 ) exhibits a methane Faraday efficiency (FE CH4 ) of 70.03 % with a turnover frequency (TOF CH4 ) of 9946.7 h −1 at an industrial-scale current density of 150 mA cm −2 in a flow cell. Detailed studies indicate the copious oxygen vacancies in the Cu/ceria-H 2 are conducive to regulating the surface microelectronic structure with stabilized Cu + active center. Furthermore, density functional theory calculations and operando ATR-SEIRAS demonstrate that the Cu/ceria-H 2 can markedly enhance the activation of CO 2 , facilitate the adsorption of pivotal intermediates *COOH and *CO, thus ultimately enabling the high selectivity for CH 4 production. This study presents deep insights into designing effective electrocatalysts for CO 2 to CH 4 conversion by controlling the surface microstructure via the reaction atmosphere.}, archive = {J_ANGEW}, author = {Fang Huang and Xiangyu Chen and Huanhuan Sun and Qingduo Zeng and Junjie Ma and Dong Wei and Jinliang Zhu and Zhengjun Chen and Taoyuan Liang and Xucai Yin and Xijun Liu and Jing Xu and Huibing He}, doi = {10.1002/anie.202415642}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {3}, pages = {e202415642}, shortjournal = {Angew.

Nevertheless, achieving precise J–T distortion control over catalytic sites to enhance CO 2 adsorption/activation and target-product desorption remains a formidable challenge. In this work, we successfully induced J–T lattice distortion in neighboring Ni sites by exchanging high-spin Mn 2+ into Ni−O−Ni nodes. EXAFS results and DFT simulations revealed that the highly asymmetric Ni−O−Mn nodes induced structural contraction (shortened Ni−O bonds) in the adjacent Ni−O lattice. The magnetic hysteresis loop (M−H) confirmed that the introduction of Mn 2+ increased the number of spin electrons, thereby increasing the magnetization intensity. The spin mismatch between photogenerated electrons and holes suppressed charge recombination. Significantly, the d orbitals of the Ni sites in the Ni−O−Mn nodes exhibited strong orbital hybridization with the p orbitals of CO 2 , as evidenced by the enhanced d-p orbital overlap, facilitating rapid CO 2 adsorption and activation.

The mechanistic investigation demonstrated that the cocrystal precursors of 4,4′,4′′-(1,3,5-triazine-2,4,6-triyl)trianiline ( TAPT ) and p -toluenesulphonic acid ( PTSA ) sufficiently regulate the crystalline structure of COF.

Moreover, the protonation degree of TAPT amines, which tuned nucleophilic directionality, enabled the sequential progression of intra- and interlayer imine condensation reactions, inhibiting the formation of amorphous polymers.

  @article{ , abstract = {In the context of oxygen evolution reaction (OER), the construction of high-valence transition metal sites to trigger the lattice oxygen oxidation mechanism is considered crucial for overcoming the performance limitations of traditional adsorbate evolution mechanism. However, the dynamic evolution of lattice oxygen during the reaction poses significant challenges for the stability of high-valence metal sites, particularly in high-current-density water-splitting systems. Here, we have successfully constructed Co−O−Fe catalytic active motifs in cobalt-iron Prussian blue analogs (CoFe-PBA) through oxygen plasma bombardment, effectively activating lattice oxygen reactivity while sustaining robust stability. Our spectroscopic and theoretical studies reveal that the Co−O−Fe bridged motifs enable a unique double-exchange interaction between Co and Fe atoms, promoting the formation of high-valence Co species as OER active centers while maintaining Fe in a low-valence state, preventing its dissolution. The resultant catalyst (CoFe-PBA-30) requires an overpotential of only 276 mV to achieve 1000 mA cm −2 . Furthermore, the assembled alkaline exchange membrane electrolyzer using CoFe-PBA-30 as anode material achieves a high current density of 1 A cm −2 at 1.76 V and continuously operates for 250 hours with negligible degradation.

Several carboxylate anions, which are all much smaller than the cavities of the tunnels, were visualized by X-ray crystallography when nanoconfined in CD-MOFs, despite the large voids present in the tunnels. These anions were found to be aligned within a planar array defined by four K + cations, positioned around the periphery of the tunnels. The strong electrostatic interactions between the carboxylate anions and the K + cations dictate the orientation of the anions and override the influence of all other possible noncovalent bonding interactions between them and the tunnels. Consequently, the aligned pairs of γ-cyclodextrin rings constituting the tunnels become distorted, resulting in them having lower symmetry and fewer disordered carboxylate anions in the solid state.

Here, we developed a miR NA- i nitiated a ssembled pre-PRO TAC (miRiaTAC) platform that enables the on-demand activation and termination of target degradation in a cell type-specific manner. Using miRNA-21 as a model, we engineered DNA hairpins labeled with JQ-1 and pomalidomide and facilitated the modular assembly of DNA-encoded pre-PROTACs through a hybridization chain reaction. This configuration promoted the selective polyubiquitination and degradation of BRD4 upon miR-21 initiation, highlighting significant tumor selectivity and minimal systemic toxicity. Furthermore, the platform incorporates photolabile groups, enabling the precise optical control of pre-PROTACs during DNA assembly/disassembly, mitigating the risk of excessive protein degradation. Additionally, by introducing a secondary ligand targeting CDK6, these pre-PROTACs were used as a modular scaffold for the programmable assembly of active miRiaTACs containing two different warheads in exact stoichiometry, enabling orthogonal multitarget degradation. The integration of near-infrared light-mediated photodynamic therapy through an upconversion nanosystem further enhanced the efficacy of the platform with potent in vivo anticancer activity.

  @article{ , abstract = {AgGaS 2 (AGS) is the most commonly used commercial infrared nonlinear optical (IR NLO) material. However, AGS has a narrow band gap ( E g =2.58 eV) and a low laser-induced damage threshold (LIDT), primarily attributed to its mobile liquid-like Ag + constituent and the unstable Ag−S chemical bond. Herein, we propose a “band reformation of AGS” strategy, which leads to the successful syntheses of four lanthanide sulfides, LiLnGeS 4 (Ln=La−Nd), crystalizing in an asymmetric Ama 2 structure. LiLaGeS 4 demonstrates that eliminating the presence of Ag-4 d band increases the E g to 3.32 eV and enhances the LIDT (14–29×AGS, measured by both powder and single crystal); while increasing the nonbonding density of states of the S-3 p band enhances the 2 nd -nonlinear optical coefficient (1.06×AGS). Besides, the bond length discrepancy between [LiS 4 ], [GeS 4 ] and [LaS 8 ] units leads to a moderate birefringence (Δ n =0.052). Such a unique structure further results in extremely small thermal expansion with α L =0.41–1.74×10 −5 K −1 , along different crystallographic axes. Our theoretical studies indicate that the synergy of the structure building units contribute to the second harmonic generation performance.

Further studies confirmed that the SSFL and RTP could be attributed to the introduction of oxygen functional group (e. g., C=O) in the skeleton of O-CNs, thus minimizing the aggregation caused quenching effect, facilitating intersystem crossing, and stabilizing the excited triplet states. The specific thermal-stimuli production of UV DF is deemed to be the relatively large energy gap between ground and excited singlet states as well as an effective triplet-triplet annihilation. Notably, the emission maximum of UV DF locates at ~310 nm with an ultra-narrow full width at half maximum (FWHM) down to 19 nm, so it is completely invisible to the naked eyes, but detectable by a UV camera.

  @article{ , abstract = {Spinel oxides have emerged as highly active catalysts for the oxygen evolution reaction (OER). Owing to covalency competition, the OER process on spinel oxides often follows an arduous adsorbate evolution mechanism (AEM) pathway. Herein, we propose a novel rare-earth sites substitution strategy to tune the lattice oxygen redox of spinel oxides and bypass the AEM scaling relationship limitation. Taking NiCo 2 O 4 as a model, the incorporation of Ce into the octahedral site induces the formation of Ce−O−M (M=Ni, Co) bridge, which triggers charge redistribution within NiCo 2 O 4 . The developed Ce−NiCo 2 O 4 exhibits remarkable OER activity with a low overpotential, satisfactory electrochemical stability, and good practicability in anion-exchange membrane water electrolyzer. Theoretical analyses reveal that OER on Ce−NiCo 2 O 4 surface follows a more favorable lattice oxygen mechanism (LOM) pathway and non-concerted proton-electron transfers compared to pure NiCo 2 O 4 , as also verified by pH-dependent behavior and in situ Raman analysis. The 18 O-labeled electrochemical mass spectrometry provides direct evidence that the oxygen released during the OER originates from the lattice oxygen of Ce−NiCo 2 O 4 . We discover that electron delocalization of Ce 4 f states triggers charge redistribution in NiCo 2 O 4 through the Ce−O−M bridge, favoring antibonding state occupation of Ni−O bonding in [Ce−O−Ni] unit site, thereby activating lattice oxygen redox of NiCo 2 O 4 in OER.

In PDH testing, the total selectivity of by-products (CH 4 and C 2 H 6 ) significantly decreases to 4 % for CoBi catalysts due to the static Bi-doping, compared with 16 % for Co-supported catalysts.

Although significant attention has been devoted to seeking new catalysts, the problem of catalyst passivation remains underexplored. Herein, we find that metal-N coordination has a previously overlooked role in preventing the catalyst passivation. In the case of nickel, the Ni catalyst reacts with S 8 to produce NiS x compounds on the surface, leading to catalyst passivation and slow the kinetics of LiPSs conversion. In contrast, when Ni is coordinated with N (typically Ni−N 4 ), S 8 remains stable on the surface. The Ni−N 4 exhibits excellent resistance to passivation and rapid kinetics of LiPSs conversion.

  @article{ , abstract = {Managing safety and supply-chain risks associated with lithium-ion batteries (LIBs) is an urgent task for sustainable development. Aqueous proton batteries are attractive alternatives to LIBs because using water and protons addresses these two risks. However, most host materials undergo large volume changes upon H + intercalation, which induces intraparticle cracking to accelerates parasitic reactions. Herein, we report that Mo 3 Nb 2 O 14 bronze exhibits reversible H + intercalation (200 mAh g −1 ) with a Coulombic efficiency of 99.7 % owing to near-zero volume change and solid-solution-type phase transition. Combination of experimental and theoretical analyses clarifies that rotation and shrinkage of open tunnels, which consist of flexible corner-sharing Mo/NbO n polyhedra, relieve local structural distortions upon H + intercalation to suppress intraparticle cracking. The prototype full cell of an aqueous proton battery with a Mo 3 Nb 2 O 14 anode operates stably over 1000 charge/discharge cycles.

  @article{ , abstract = {Polyoxometalates (POMs) are ideal components for reversible multi-electron storage in energy technologies. To-date, most redox-applications employ only single, individual POM species, which limits the number of electrons that can be stored within a given potential window. Here, we report that spontaneous redox self-equilibration during cluster synthesis leads to the formation of two structurally related polyoxovanadates which subsequently aggregate into co-crystals. This results in systems with significantly increased redox reactivity. The mixed POM system was formed by non-aqueous self-assembly of a vanadate precursor in the presence of Mg 2+ , resulting in two mixed-valent (V IV/V ) species, [(MgOH)V 13 O 33 Cl] 4− (= {MgV 13 } ) and the di-vanadium-functionalized species [V 14 O 34 Cl] 4− (= {V 14 } ), which co-crystallize in a 1 : 1 molar stoichiometry. Experimental data indicate that in the native state, {MgV 13 } is reduced by three electrons, and {V 14 } is reduced by five electrons. Electrochemical studies in solution show, that the system can reversibly undergo up to fourteen redox transitions (tentatively assigned to twelve 1-electron processes and two 2-electron processes) in the potential range between −2.15 V to +1.35 V (vs Fc + /Fc).

  @article{ , abstract = {Recently, a new class of synthetic methyl methacrylate-based random heteropolymers (MMA-based RHPs) has displayed protein-like properties. Their function appears to be insensitive to the precise sequence. Here, through atomistic molecular dynamics simulation, we show that there are universal protein-like features of MMA-based RHPs that are insensitive to the sequence, and mostly depend on the overall composition. In particular, we find that MMA-based RHPs “fold” into globules with heterogeneous hydration patterns. However, the insensitivity to sequence identity observed in MMA-based RHPs dramatically changes when we substitute the backbone architecture with acrylate or replace the oxygen atom in the side chain with a nitrogen atom (methacrylamide or acrylamide). In such scenarios, the sequence contributes significantly to the compactness and the hydration of monomers. Using principal component analysis and an intersection-over-union based index, we demonstrate that different sequences may not overlap in the property space, meaning that their properties are controlled by the sequence rather than fixed composition. We further investigate the sequence-insensitive capability of the MMA-based RHPs as previously reported on bacterial phospholipase OmpLA stabilization through heterodimerization. As experimentally observed, such polymers enhance the stability of OmpLA as reliably as its native bilayer environment. The design of such MMA-based RHPs provides a sequence-insensitive alternative to protein-mimetic biomaterials that is orthogonal to the sequence-structure-function paradigm of proteins.}, archive = {J_ANGEW}, author = {Tianyi Jin and Connor W.

  @article{ , abstract = {Ring-opening metathesis polymerization (ROMP) is an effective method for synthesizing functional polymers, but since the technique typically relies on high ring strain cyclic olefins, the most common monomers are norbornene derivatives. The reliance on one class of monomer limits the obtainable properties of ROMP polymers. In this work, we investigate new bicyclic monomers synthesized via epoxidation of commercial dienes. DFT estimates of these monomers’ ring strains suggests a significant increase in strain for cyclic olefins containing allylic epoxides. We found that the eight-membered ( 3,4-COO ) and five-membered ( CPO ) cyclic olefins were particularly effective for ROMP. CPO was of especially intriguing due to its excellent polymerizability when compared to the limited reactivity of other five-membered rings. Unlike polynorbornenes, the resulting polymers of both monomers displayed glass transition temperatures well below room temperature. Interestingly, poly( 3,4-COO ) showed both high stereo- and regioregularity while poly( CPO ) showed little regularity. Both polymers could be readily modified via post-polymerization ring-opening of the reactive allylic epoxides.

This study introduces a glycocalyx model allowing for the first time to control spatial organization and heterogeneity of the glycan moieties.

To identify new nylon-recycling biotechnologies, targeted genome mining was used to identify thermostable enzymes capable of degrading polyamides. Here, we describe the characterization of a novel protein sourced from Thermovenabulum gondwanense : TvgC. TvgC is extremely stable, exhibiting a melting temperature of 93 °C and no detectable losses in hydrolytic activity after one week at 60 °C. While nylonases primarily process nylon-6, TvgC catalysed the degradation of both nylon-6 and nylon-6,6 films, which are considerably more difficult to degrade. Finally, conversion experiments demonstrate that TvgC achieves a 1.2 wt % conversion of nylon-6 film, comparable to that of the most highly engineered nylonases.

However, the luminescent properties of traditional ionic copper-iodine clusters are often closely associated with low-energy cluster-centered triplet emission, which will redshift further as the Cu⋅⋅⋅Cu bond length decreases. This article utilizes a pressure-treated strategy to achieve an anomalous pressure-induced blue-shifted luminescence phenomenon in ionic Cu 4 I 6 (4-dimethylamino-1-ethylpyridinium) 2 crystals for the first time, which is based on dominant through-space charge-transfer (TSCT). Herein, we reveal that the more advantageous through-space interactions in the competition between cuprophilic interactions and through-space interactions can lead to a blue-shifted luminescence. High-pressure angle-dispersive X-ray diffraction and high-pressure infrared experiments show that the enhanced through-space interactions mainly originate from forming new intermolecular C−H⋅⋅⋅I hydrogen bonds and the enhancement of van der Waals interactions between organic cations and anionic clusters. Theoretical calculations and experimental studies of excited-state dynamics confirm that the blue-shifted emission is due to the increased energy gap between the excited triplet and ground states caused by the electron delocalization under stronger through-space interactions.

The structure–activity relationship between the through-space conjugation and charge-transport behavior of the prepared folded helical o -HP derivatives is experimentally and theoretically investigated.

Moreover, scanning tunneling microscopy-break junction measurements reveal that the stable regular helical structures of o -HP derivatives open-up dominant through-space charge-transport pathways, and the single-molecule conductance is enhanced by more than 70 % by strengthening through-space conjugation with pyridine and pyrazine. However, the through-bond charge transport pathways contribute much less to the conductance of o -HP derivatives.

Here, pillaring the multilayer graphene membrane with a metal–organic framework (MOF) demonstrates the substantial impact of a versatile interlayer design in tackling these issues. Unlike regular composite separators reported so far, the participation of tri-metallic Ni−Co−Mn MOF as pillars supports the construction of an ion-channel interconnected interlayer structure, unexpectedly balancing the interfacial concentration polarization, spatially confining the soluble polysulfides, and vastly affording the lithiophilic sites for highly efficient polysulfide sieving/conversion.

Combining experimental results and molecular dynamics simulations, it has been demonstrated that cerium dioxide layers with FLPs sites can decompose water molecules, capture hydroxyl anions, and repel chloride ions simultaneously. DFT theoretical analysis indicates that the FLP sites regulate the Ce 4 f−O 2p−Ni 3d gradient orbital coupling, providing additional oxygen non-bonding (O NB ) to stabilize the Ni−O bond and optimize the adsorption strength of intermediates, thereby breaking the *OH and *OOH scaling relationship.

This superfamily has diverse catalytic functions and could provide a rich new source of biocatalysts for synthesis and industrial processes. Through systematic comparisons of directed evolution trajectories for a non-native, remote C( sp 3 )−H hydroxylation reaction, we demonstrate that the stabilized redesign can be evolved more efficiently than the wild-type enzyme. After three rounds of directed evolution, we obtained a 6-fold activity increase from the wild-type parent and an 80-fold increase from the stabilized variant. To generate the initial stabilized variant, we identified multiple structural and sequence constraints to preserve catalytic function. We applied these criteria to produce stabilized, catalytically active variants of a second Fe(II)/αKG enzyme, suggesting that the approach is generalizable to additional members of the Fe(II)/αKG superfamily.

It is shown that anions and H 2 O, but not anions and cations, are preferentially immobilized at different sites of zwitterionic polymers, facilitating the free migration of Zn 2+ and reducing the side reactions. This immobilization can be associated with the dipole moment of zwitterionic polymers. As a result, poly[3-dimethyl(methacryloyloxy ethyl) ammonium propane sulfonate] (PDMAPS) stands out from a series of zwitterionic polymers and outperforms the other candidates in electrochemical performance.

To balance ion transport kinetics and interfacial stability over wide temperature range, herein a bifunctional electrolyte (EAFP) tailoring the electrode/electrolyte interphase with 1,3-propanesultone as an additive was developed. The resulting cathode-electrolyte interphase with an inorganic inner layer and an organic outer layer possesses high mechanical stability and flexibility, alleviating stress accumulation and maintaining the structural integrity of the NCM811 cathode. Meanwhile, the inorganic-rich solid electrolyte interphase inhibits electrolyte side reactions and facilitates fast Li + transport. As a result, the Li||Li cells exhibit stable performance in extensive temperatures with low overpotentials, especially achieving a long lifespan of 1000 h at 30 °C. Furthermore, the optimized EAFP is also suitable for LiFePO 4 and LiCO 2 cathodes (1000 cycles, retention: 67 %). The Li||NCM811 and graphite||NCM811 pouch cells with lean electrolyte (g/Ah grade) operate stably, verifying the broad electrode compatibility of EAFP. Notably, the Li||NCM811 cells can operate in wide climate range from −40 °C to 60 °C.

  @article{ , abstract = {Artificial polymer solid electrolyte interphases (SEIs) with microphase-separated structures provide promising solutions to the inhomogeneity and cracking issues of natural SEIs in lithium metal batteries (LMBs). However, achieving homogeneous ionic conductivity, excellent mechanical properties, and superior interfacial stability remains challenging due to interference from hard-phase domains in ion transport and solid-solid interface issues with lithium metal. Herein, we present a dynamic supramolecular ion-conducting poly (urethane-urea) interphase (DSIPI) that achieves these three properties through modulating the hard-phase domains and constructing a composite SEI in situ. The soft-phase polytetrahydrofuran backbone, featuring loose Li + −O coordinating interactions, ensures uniform Li + transport. Concurrently, sextuple hydrogen bonds in the hard phase dissipate strain energy through sequential bond cleavage, thereby imparting exceptional mechanical properties. Moreover, enriched bis (trifluoromethanesulfonyl) imide anion (TFSI − ) in DSIPI promotes the in situ formation of a stable polymer-inorganic composite SEI during cycling. Consequently, the DSIPI-protected lithium anode (DSIPI@Li) enables symmetric cells with exceptional cyclability exceeding 4,000 hours at an ultra-high current density of 20 mA cm −2 , thereby demonstrating excellent cycling stability.

Application of S-adenosylmethionine (SAM)-dependent methyltransferases (MTs) in biotechnological hosts such as Escherichia coli lowers the environmental impact of alkylation compared to chemical synthesis and facilitates regio- and chemoselective alkyl chain transfer. Here, we address the limiting factor for SAM synthesis, methionine supply, to accelerate in vivo methylation activity. Introduction of the direct sulfurylation pathway, consisting of O-acetylhomoserine sulfhydrolase (ScOAHS) and O-acetyltransferase (ScMET2), from S. cerevisiae into E. coli and supplementation with methanethiol or the corresponding disulfide improves atom-economic methylation activity in three different MT reactions. Up to 17-fold increase of conversion compared to the sole expression of the MT and incorporation of up to 79 % of the thiol compound added were achieved. Promiscuity of ScOAHS allowed in vivo production of methionine analogues from organic thiols. Further co-overproduction of a methionine adenosyltransferase yielded SAM analogues which were further transferred by MTs onto different substrates. For methylation of non-physiological substrates, conversion rates up to 73 % were achieved, with an isolated yield of 41 % for N-methyl-2,5-aminonitrophenol.

Our results show a correlation between the degree of functionalization and the twist angle of tBLG. This correlation was determined through Raman spectroscopy, where areas with larger twist angles exhibited a lower HATCN peak intensity compared to areas with smaller twist angles.

The strong ionic polarization of the molten salt promotes the breakage of Ti−O bonds in the TiO 2 support, and hence decreases the energy barrier for the formation of interfacial bonds. Consequently, a high-intensity SMSI state is achieved in TiO 2 supported Ir nanoclusters, evidenced by a large number of Ir−Ti bonds at the interface, at a low temperature of 350 °C.

Stable and affordable redox-active materials are essential for the commercialization of AIRFBs, yet the battery stability must be significantly improved to achieve practical value. Herein, ferrous complexes combined with the triisopropanolamine (TIPA) ligand are identified as promising anolytes to extend battery life by reducing cross-contamination due to a pronounced steric hindrance effect. The coordination structure and failure mechanism of our Fe-TIPA complexes were determined by molecular dynamics simulation and spectroscopic experiments. By coupling with [Fe(CN) 6 ] 4−/3− , Fe-TIPA/Fe-CN AIRFBs retained excellent stability exceeding 1831 cycles at 80 mA ⋅ cm −2 , yielding an energy efficiency of ~80 % and maintaining a steady discharge capacity. Moreover, the all-soluble electrolyte was tested in an industrial-scale Fe-TIPA/Fe-CN AIRFB prototype energy storage system, where an energy efficiency of 81.3 % was attained. Given the abundance of iron resources, we model the TIPA AIRFB electrolyte cost to be as low as 32.37 $/kWh, which is significantly cheaper than the current commercial level.

The anchoring of the silane has been characterized by means of FTIR and solid-state NMR spectroscopies, and the grafting density was determined by thermogravimetric and N 2 physisorption analyses. The silane moieties induce a partial decrease of the shielding of the valence electrons of the Ti ions at the surface, and a local modification of their crystal field, as demonstrated by XPS and UV/Vis spectroscopy, respectively. The changes in coordination and the produced oxygen vacancies result in the formation of Ti 3+ defects localized in the sub-surface region, as revealed by EPR spectroscopy. These paramagnetic centers are stabilized in the silanized samples, as the electron transfer to O 2 is efficiently inhibited even under UV irradiation. However, the amount of Ti 3+ centers appears to be correlated with the singlet oxygen ( 1 O 2 ) formation rate. Accordingly, epoxidation of limonene under UV light, chosen as a model photocatalytic reaction triggered by 1 O 2 , occurred with higher selectivity when TiO 2 was silanized and upon simultaneous NIR irradiation.

  @article{ , abstract = {Redox reactions on the surface of transition metal oxides are of broad interest in thermo, photo, and electrocatalysis. H 2 temperature-programmed reduction (H 2 -TPR) is commonly used to probe oxide reducibility by measuring the rate of H 2 consumption during temperature ramps, assuming that this rate is controlled by oxide reduction. However, oxide reduction involves several elementary steps, such as H 2 dissociation and H-spillover, before surface reduction and H 2 O formation occur. In this study, we evaluated the kinetics of H 2 consumption over CeO 2 and Pt/CeO 2 with varying Pt loadings and structures to identify the elementary steps probed by H 2 -TPR. Literature often attributes changes in H 2 -TPR characteristics with Pt addition to increased CeO 2 reducibility. However, our analysis revealed that the H 2 consumption rate is measurement of the rate of H-spillover at Pt-CeO 2 interfaces and is determined by the concentration of Pt species on Pt nanoclusters that dissociate H 2 . Therefore, lower temperature H 2 consumption observed with Pt addition does not indicate higher CeO 2 reducibility.

This screening process involves regression machine learning (ML) algorithms and a compressed-sensing data-analytics approach parameterized with density-functional inputs. The results demonstrate that Cu/Ag and Zn/Ag can efficiently activate and hydrogenate NO with small Φ max ( η ), a grand-canonical adaptation of the G max ( η ) descriptor, and exhibit higher affinity to NO over H adatoms to suppress the competing hydrogen evolution reaction. The NH 3 selectivity is mainly determined by the s orbitals of the doped single-atom near the Fermi level.

  @article{ , abstract = {Whilst energetic and kinetic aspects of folding processes are meanwhile well understood for natural biomacromolecules, the folding dynamics in so far studied artificial foldamer counterparts remain largely unexplored.

Here we present an asymmetric perylene bisimide dimer (bis-PBI 1 ) that possesses conformational chirality in its folded state. Owing to the large interconversion barrier (≥116 kJ mol −1 ), four stereoisomers could be separated and isolated. Since the interconversion between these stereoisomers requires the foldamer to first open and then to re-fold, the transformation of one stereoisomer into others allowed us to ‘visualize’ the dynamics of folding with time and determine its lifetimes and the energetic barriers associated with the folding process. Supported by quantum chemical calculations, we identified the open structure to be only a fleetingly metastable state of higher energy.

  @article{ , abstract = {Aqueous all-organic batteries (AAOBs) have emerged as a hot topic but their development was plagued by limited choices of anode materials, generally facing an intractable trade-off between low potential and high stability. Here, we propose a novel π-electron bridge engineering strategy to explore a class of 2D dioxin-bridged redox covalent organic polymer (RCOP) as trade-off-breaking anodes for high-voltage AAOBs. By establishing a tunable RCOP platform, we perform theoretical study to scrutinize how bridge units between active sites affect the electrode potential and redox activity for the first time. We discover that compared to common pyrazine bridge, the weakened conjugation and strong electron donor character of the proposed dioxin bridge can induce elevated LUMO level and enriched π-electron populations in active sites, heralding a low electrode potential and enhanced redox activity. Besides, the nonaromaticity-induced molecular flexibility of dioxin bridge mitigates intermolecular stacking for sufficient active sites exposure. To experimentally corroborate this, a new dioxin-bridged 2D RCOP (D-HATN) and its pyrazine-bridged analogue (P-HATN) are synthesized for proof-of-concept demonstration. D-HATN displays excellent compatibility with Na + /Zn 2+ /NH 4 + /H 3 O + and obviously lower redox potentials in various dilute electrolytes compared to P-HATN and most reported organic anodes, while featuring rapid Grotthuss-type proton conduction and unprecedented durability in acid – 91.8 % capacity retention after 20000 cycles. Thus, the D-HATN-involved all-organic proton battery delivers an average output voltage of 0.75 V, which can be further elevated to 1.63 V with alkaline-acidic hybrid electrolyte design, affording markedly-increased specific energy.}, archive = {J_ANGEW}, author = {Linfeng Zhong and Cong Liu and Yang Zhang and Jing Li and Fan Yang and Zishou Zhang and Dingshan Yu}, doi = {10.1002/anie.202413971}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {2}, pages = {e202413971}, shortjournal = {Angew.

Herein, two polymer acceptors with absorption beyond 1000 nm, namely P4TOC-DCBT and P4TOC-DCBSe, were designed and synthesized. The two polymers possess rigid structure and good conformational stability, which is beneficial for reducing energetic disorder and suppressing dark current.

In particular, the formation of C(sp 2 )−C(sp 3 ) bonds is crucial for constructing biologically active molecules, including pharmaceuticals and agrochemicals. In this study, we present the previously elusive coupling between gaseous alkanes and (hetero)aryl bromides, achieved through a combination of Hydrogen Atom Transfer (HAT) photocatalysis and nickel-catalyzed cross coupling at room temperature. Utilizing flow technology allowed us to conduct this novel coupling reaction with reduced reaction times and in a scalable fashion, rendering it practical for widespread adoption in both academia and industry.

Experimental validation of the proposed zwitterionic polymer electrolyte (ZPE) showcases satisfactory parameters: ion conductivity (0.59 mS cm −1 ), ion migration numbers (0.82), and activation energy (0.016 eV). Electrochemical analysis on Li|ZPE|Li symmetric batteries demonstrate sustained plating/stripping performance exceeding 3000 hours at a current density of 0.2 mA cm −2 . Assembled NCM|ZPE|Li batteries exhibit stable cycling over 1400 cycles at 4.3 V, with a capacity retention ratio of 92.3 %. Moreover, even under ultra-high voltages of 4.5 V and 4.7 V, NCM|ZPE|Li batteries display stable cycling performances.

  @article{ , abstract = {Increasing the diversity of bio-based polymers is needed to address the combined problems of plastic pollution and greenhouse gas emissions. The magnitude of the problems necessitates rapid discovery of new materials; however, identification of appropriate chemistries maybe slow using current iterative methods. Machine learning (ML) methods could significantly expedite new material discovery and property identification. Here, PolyAGM, a ML algorithm using graph kernel methods, is introduced and used to predict the properties of block copolymers and identify the responsible structural ‘motifs’. It applies a “fingerprinting” method to convert Graph representations of polymers into numerical vectors. The Graphs explicitly encode the entire copolymer of atoms and bonds such that the sequencing of chemical features and polymer chain length are included, alongside relevant stereochemical information. PolyAGM gives predictions for both thermal and mechanical properties that are in good agreement with experimental measurements. This work focuses on predicting the properties of bio-derived ABA-block polymer thermoplastic elastomers, but the general fingerprinting technique of PolyAGM should be relevant to other application fields.}, archive = {J_ANGEW}, author = {Shannon R.

In this study, we search across pathways for common nonenzymatic conditions for a recurring chemical transformation in metabolism: alkene hydration. The mild conditions that we identify (Fe oxides such as green rust) apply to all hydration reactions of the rTCA cycle and gluconeogenesis, including the hydration of phosphoenolpyruvate (PEP) to 2-phosphoglycerate (2PGA), which had not previously been reported under nonenzymatic conditions.

  @article{ , abstract = {Current methods for proteomimetic engineering rely on structure-based design. Here we describe a design strategy that allows the construction of proteomimetics against challenging targets without a priori characterization of the target surface. Our approach employs (i) a 100-membered photoreactive foldamer library, the members of which act as local surface mimetics, and (ii) the subsequent affinity maturation of the primary hits using systems chemistry. Two surface-oriented proteinogenic side chains drove the interactions between the short helical foldamer fragments and the proteins. Diazirine-based photo-crosslinking was applied to sensitively detect and localize binding even to shallow and dynamic patches on representatively difficult targets. Photo-foldamers identified functionally relevant protein interfaces, allosteric and previously unexplored targetable regions on the surface of STAT3 and an oncogenic K-Ras variant. Target-templated dynamic linking of foldamer hits resulted in two orders of magnitude affinity improvement in a single step. The dimeric K-Ras ligand mimicked protein-like catalytic functions. The photo-foldamer approach thus enables the highly efficient mapping of protein-protein interaction sites and provides a viable starting point for proteomimetic ligand development without a priori structural hypotheses.}, archive = {J_ANGEW}, author = {Edit Wéber and Péter Ábrányi-Balogh and Bence Nagymihály and Dóra K.

Such constraints have hindered the widespread use of crystals as actuation materials. In this minireview, we focus on crystal actuation by employing more universal physical phenomena (the photothermal effect and photothermally resonated natural vibration) and quantitatively evaluate actuation performance. Both mechanisms, particularly the latter, outperformed conventional photomechanical crystal activation in terms of both speed (maximum: 1,350 Hz) and the useful wavelength range (ultraviolet to near-infrared). The oscillation frequencies of the crystals exceeded those of polymers, efficiently filling the gap between soft and hard materials. Both the photothermal effect and natural vibration can actuate any crystal that absorbs light.

Their optical properties and luminescence mechanisms were systematically elucidated by experiments combined with density functional theory calculations. The bright cyan-fluorescent (C 19 H 18 P) 2 CuI 3 with high photoluminescence quantum yield (PLQY) of 77 % is attributed to the self-trapped exciton emission. Differently, the broad yellow-orange fluorescence of (C 19 H 18 P) 2 Cu 4 I 6 displays a remarkable PLQY of 83 %. Its luminescence mechanism is mainly attributed to the combined effects of metal/halide-to-ligand charge transfer and cluster-centered charge transfer, which effects stem from the strong Cu−Cu bonding interactions in the (Cu 4 I 6 ) 2− clusters.

Moreover, a very high accuracy is achieved by using the extreme gradient boosting algorithm, with the Pearson's correlation coefficient of 0.92. Finally, we use this ML model to predict the E b of thin films, which is difficult to achieve using the current quantum-chemical calculations due to the large structural disorder. Remarkably, the predicted thin-film E b values are fully consistent with the results of temperature-dependent photoluminescence spectra. Therefore, our work provides an accurate and efficient approach to predict the solid-state E b and would be helpful to accelerate the exploitation of novel promising organic photovoltaic materials.}, archive = {J_ANGEW}, author = {Lingyun Zhu and Miaofei Huang and Guangchao Han and Zhixiang Wei and Yuanping Yi}, doi = {10.1002/anie.202413913}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {1}, pages = {e202413913}, shortjournal = {Angew.

  @article{ , abstract = {Therapeutic intervention targeting mRNA typically aims at reducing the levels of disease-causing sequences. Achieving the opposite effect of blocking the destruction of beneficial mRNA remains underexplored. The degradation of mRNA starts with the removal of poly(A) tails, reducing their stability and translational activity, which is mainly regulated by the CCR4-NOT complex. The subunit NOT9 binds various RNA binding proteins, that recruit mRNA in a sequence-specific manner to the CCR4-NOT complex to promote their deadenylation. These RNA binding proteins interact with NOT9 through a helical NOT9 binding motif, which we used as a starting point for development of the hydrocarbon stapled peptide NIP-2 . The peptide ( K D =60.4 nM) was able to inhibit RNA-binding (IC 50 =333 nM) as well as the deadenylation activity of the CCR4-NOT complex in vitro while being cell-permeable (cell-permeability EC 50 =2.44 μM). A co-crystal structure of NIP-2 bound to NOT9 allowed further optimization of the peptide through point mutation leading to NIP-2-H27A-N 3 ( K D =122 nM) with high cell permeability (cell-permeability EC 50 =0.34 μM). The optimized peptide was able to inhibit deadenylation of target mRNAs when used in HeLa cells at a concentration of 100 μM, demonstrating the feasibility of increasing mRNA stability.}, archive = {J_ANGEW}, author = {Sunit Pal and Ilja Gordijenko and Stefan Schmeing and Somarghya Biswas and Yasemin Akbulut and Raphael Gasper and Peter 't Hart}, doi = {10.1002/anie.202413911}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {1}, pages = {e202413911}, shortjournal = {Angew.

Although photoirradiation is striking as a noncontact and nondestructive manipulation tool to optimize physical properties, optical control of antiferroelectricity still remains unexplored.

  @article{ , abstract = {Earth-abundant manganese oxides (MnO x ) were competitive candidates when screening catalysts for ammoxidation of alcohols into nitriles due to their redox property. However, over-oxidation and possible acid-catalyzed hydrolysis of nitriles into amides still limited the application of MnO x in nitrile synthesis. In this work, manganese carbodiimide (MnNCN) was first reported to be robust for the ammoxidation of alcohols into nitriles, avoiding over-oxidation and the hydrolysis. Besides the high activity and selectivity, MnNCN demonstrated wide substrate scope including the ammoxidation of primary alcohols into nitriles, the oxidative C−C bonds cleavage and ammoxidation of secondary alcohols, phenyl substituted aliphatic alcohols, and diols into nitriles. Controlled experiments and DFT calculation results revealed that the excellent catalytic performance of MnNCN originated from its high ability in the activation of O 2 molecules, and favorable oxidative dehydrogenation of C=N bonds in the aldimine intermediates (RCH=NH) into nitriles, inhibiting the competitive side reaction of the oxidation of aldehydes into carboxylic acids, followed to amide byproducts. Moreover, the hydrolysis of nitriles was also inhibited over MnNCN for its weak acidity as compared with MnO x .

However, further optimizing sub-2 nm sites to break the activity–stability trade-off due to excessive interactions remains significant challenges. Accordingly, for the first time, we propose synergizing SMSI with reactive metal-support interactions (RMSI). Comprehensive characterization confirms that the SMSI stabilizes the metal and regulates the aggregation of Ni 1 into Ni n site within sub-2 nm. Meanwhile, RMSI modulates Ni n through sufficiently activating P in the support and eventually generates sub-2 nm metal phosphide Ni 2 P cluster (Ni 2 P n ). The synergetic metal-support interactions triggered the adaptive coordination and electronic structure optimization of Ni 2 P n , leading to the desired substrate adsorption-desorption kinetics. Consequently, the activity of Ni 2 P n site greatly enhanced towards the selective hydrogenations of p -chloronitrobenzene and alkynyl alcohol. The formation rates of target products are up to 20.2 and 3.0 times greater than that of Ni 1 and Ni n site, respectively.

  @article{ , abstract = {All-solid-state Li−S batteries (ASSLSBs) due to high theoretical energy density and exceptional safety are highly desirable for electric aircraft. However, as the flight altitude rises, the low-temperature performance is hampered by inadequate practical capacity. Here, we discover that low-temperature sulfur utilization is constrained by the multi-step endothermic conversion reaction. By introducing multi-chalcogen to modulate the local entropy, a short-chain molecule cathode is designed to shorten the reduction pathways and enhance low-temperature discharge capacity. Furthermore, the mismatched lithiation lattice of the short-chain cathode reduces the decomposition energy barriers, thus enhancing low-temperature charge/discharge reversibility. The designed short-chain cathode exhibits high cathode utilization (99.4 %) and cycling stability (400 cycles, 92.2 % retention) at room temperature, as well as delivers excellent discharge capacity (579.6 mAh g −1 , −40 °C) and cycling performance (100 cycles, 98.4 % retention, 394.9 Wh kg − 1electrode, −20 °C) at low temperature.

  @article{ , abstract = {Single-atom nanozymes (SAzymes) with ultrahigh atom utilization efficiency have been extensively applied in reactive oxygen species (ROS)-mediated cancer therapy. However, the high energy barriers of reaction intermediates on single-atom sites and the overexpressed antioxidants in the tumor microenvironment restrict the amplification of tumor oxidative stress, resulting in unsatisfactory therapeutic efficacy. Herein, we report a multi-enzyme mimetic MoCu dual-atom nanozyme (MoCu DAzyme) with various catalytic active sites, which exhibits peroxidase, oxidase, glutathione (GSH) oxidase, and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase mimicking activities. Compared with Mo SAzyme, the introduction of Cu atoms, formation of dual-atom sites, and synergetic catalytic effects among various active sites enhance substrate adsorption and reduce the energy barrier, thereby endowing MoCu DAzyme with stronger catalytic activities. Benefiting from the above enzyme-like activities, MoCu DAzyme can not only generate multiple ROS, but also deplete GSH and block its regeneration to trigger the cascade amplification of oxidative stress. Additionally, the strong optical absorption in the near-infrared II bio-window endows MoCu DAzyme with remarkable photothermal conversion performance. Consequently, MoCu DAzyme achieves high-efficiency synergistic cancer treatment incorporating collaborative catalytic therapy and photothermal therapy.

V n −RuO 2 showed high activity with a low overpotential of 227 mV at 10 mA cm −2 and outstanding stability during a 1050 h test in acidic electrolyte. Operando spectroscopic studies and theoretical calculations revealed that compared with the V single atom-doping case, the introduction of the V dimer into RuO 2 further decreases the Ru-V atomic distance and weakens the adsorption strength of the *O intermediate to the active V site, which supports the more energetically favorable oxygen radical coupling mechanism (OCM). Furthermore, the highly asymmetric Ru−O−V local structure stabilizes the surface Ru active center by lowering the valence state and increasing the resistance against overoxidation, which result in outstanding stability.

Quantitative biochemical analysis of different RNF168 constructs on H1 ubiquitylated chromatosomes with different ubiquitin chain lengths demonstrated that K63-linked polyubiquitylated H1.0 could directly stimulate RNF168 ubiquitylation activity by enhancing the affinity between RNF168 and the chromatosome.

However, the reduced PW 12 and PW 11 are incapable of adsorbing *CO due to the small energy of occupied molecular orbitals, which is the reason for the poorer activity of PW x /g-C 3 N 4 ( x =12, 11) compared with that of PW 9 /g-C 3 N 4 .

It requires thermodynamically challenging chemical transformations to be delivered under mild, aqueous conditions. 5-Methylcytosine (5mC) is a fundamentally important epigenetic modification in DNA that has major implications for biology and has emerged as a vital biomarker. Selective functionalisation of 5mC would enable new chemical approaches to tag, detect and map DNA methylation to enhance the study and exploitation of this epigenetic feature. We demonstrate the first example of direct and selective chemical oxidation of 5mC to 5-formylcytosine (5fC) in DNA, employing a photocatalytic system. This transformation was used to selectively tag 5mC. We also provide proof-of-concept for deploying this chemistry for single-base resolution sequencing of 5mC and genetic bases adenine (A), cytosine (C), guanine (G), thymine (T) in DNA on a next-generation sequencing system.

In this work, we used a thiophene-based cation 2-(thiophen-3-yl)ethan-1-aminium (3-TEA) as a spacer to form a novel 2D perovskite phase in TPSCs, which shows the most promising effect on the performance enhancement in comparison with other cations like 2-(thiophen-2-yl)ethan-1-aminium (2-TEA) and benzene-based 2-phenylethan-1-aminium (PEA). Theoretical calculations reveal that 3-TEA enables the most compact crystal packing of [SnI 6 ] 4− octahedral layers, resulting in the lowest hole effective mass and formation energy in the 2D phase.

We demonstrate this concept through the photoreduction of the sulfur-containing DNA nucleoside precursor thioanhydrouridine to 2’-deoxy-thiouridine, revealing the previously unrecognized role of bisulfide in this process. Based on quantum chemical simulations, we identify a stable chalcogen-bonding complex of the hydrosulfide anion and thionhydrouridine (HS − ⋅⋅⋅S contacts), which enables directional photoinduced electron transfer, resulting in the formation of non-canonical DNA nucleoside. We also disprove the possibility that photoreduction of thioanhydronucleosides could be initiated by hydrated electrons generated from irradiated bisulfide anions which do not interact with the chromophore.

  @article{ , abstract = {Active oxygen species (OH*/O*) derived from water electrolysis are essential for the electrooxidation of organic compounds into high-value chemicals, which can determine activity and selectivity, whereas the relationship between them remains unclear. Herein, using glycerol (GLY) electrooxidation as a model reaction, we systematically investigated the relationship between GLY oxidation activity and the formation energy of OH* (Δ G OH* ). We first identified that OH* on Au demonstrates the highest activity for GLY electrooxidation among various pure metals, based on experiments and density functional theory, and revealed that Δ G OH* on Au-based alloys is influenced by the metallic composition of OH* coordination sites. Moreover, we observed a linear correlation between the adsorption energy of GLY ( E ads ) and the d -band center of Au-based alloys. Comprehensive microkinetic analysis further reveals a volcano relationship between GLY oxidation activity, the Δ G OH* and the adsorption free energy of GLY (Δ G ads ). Notably, Au 3 Pd and Au 3 Ag alloys, positioned near the peak of the volcano plot, show excellent activity, attributed to their moderate Δ G OH* and Δ G ads , striking a balance that is neither too high nor too low.

Polymerization of phenylenediamine was initiated by Fe 3+ and Fe 2+ ions generated synchronously during the polymerization integrated with poly-aminoquinone chains to form Fe−C 12 N 8 active centers. Used as electrode materials for sodium-ion batteries, the distinctive Fe−C bond significantly boosts the structural stability, and the π-d conjugation system could facilitate electron transfer.

This lanthanide-like contraction contributes to Se's robust oxidative resistance. Here we report a selective oxidation strategy utilizing Se's strong antioxidative property to remove coexisting narrow-band gap Te impurities from Se feedstocks. This strategy selectively oxidizes volatile Te impurities into involatile TeO 2 that remains in the evaporation source, while only volatile Se deposits onto the substrate during the thermal-evaporation deposition process.

We found that neither the parent nanohoop [10]CPP nor its electron-deficient analogue aza[10]CPP actively participate in charge separation. In contrast, the nanohoops completely prevented through-space charge separation. This result is likely due to supramolecular “shielding”, because charge separation was observed in the thread that acted as reference dyad. On the other hand, the suppression of electron transfer allowed the observation of energy transfer from the porphyrin triplet to the fullerene triplet state with a lifetime of ca. 25 μs. The presence of the interlocked nanohoops therefore leads to a dramatic switch between charge separation and energy transfer.

These precursors respond to GSH or H 2 O 2 , releasing the active photosensitizer that captures DNA abasic (AP) sites and generates DNA radical cations upon photolysis, without disrupting the redox state of cells. DNA radical cations migrate freely and are eventually trapped by H 2 O and O 2 to yield DNA lesions, thus triggering DNA damage response.

  @article{ , abstract = {Inevitable leaching and corrosion under anodic oxidative environment greatly restrict the lifespan of most catalysts with excellent primitive activity for oxygen production. Here, based on Fick’ s Law, we present a surface cladding strategy to mitigate Ni dissolution and stabilize lattice oxygen triggering by directional flow of interfacial electrons and strong electronic interactions via constructing elaborately cladding-type NiO/NiS heterostructure with controlled surface thickness. Multiple in situ characterization technologies indicated that this strategy can effectively prevent the irreversible Ni ions leaching and inhibit lattice oxygen from participating in anodic reaction. Combined with density functional theory calculations, we reveal that the stable interfacial O−Ni−S arrangement can facilitate the accumulation of electrons on surficial NiO side and weaken its Ni−O covalency. This would suppress the overoxidation of Ni and simultaneously fixing the lattice oxygen, thus enabling catalysts with boosted corrosion resistance without sacrificing its activity. Consequently, this cladding-type NiO/NiS heterostructure exhibits excellent performance with a low overpotential of 256 mV after 500 h. Based on Fick's law, this work demonstrates the positive effect of surface modification through precisely adjusting of the oxygen-sulfur exchange process, which has paved an innovative and effective way to solve the instability problem of anodic oxidation.}, archive = {J_ANGEW}, author = {Shengjie Zi and Jiamin Zhu and Yue Zhai and Yang Hu and Nan Zhang and Shuhui Li and Luohua Liu and Li An and Pinxian Xi and Chun-Hua Yan}, doi = {10.1002/anie.202413348}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {1}, pages = {e202413348}, shortjournal = {Angew.

Indirect activation via reactive oxygen species (ROS) offers a high probability of contact with methane and conversion efficiency under mild conditions.

We propose the use of contact-electro-catalysis (CEC), employing polydopamine (PDA) as a catalyst that undergoes electron transfer with oxygen under ultrasound, generating ROS that drives the partial oxidation of methane (POM). Corresponding experimental results indicate that CH 3 OH and most HCHO are produced directly from CH 4 . Furthermore, through in situ characterizations, we have shown that light pretreatment of the catalysts in an oxygenated atmosphere facilitates the forming of more C=O functional groups with strong electron-withdrawing properties, thereby significantly enhancing overall product yields, particularly for CH 3 OH.

  @article{ , abstract = {The lattice oxygen mechanism (LOM) endows NiFe layered double hydroxide (NiFe-LDH) with superior oxygen evolution reaction (OER) activity, yet the frequent evolution and sluggish regeneration of lattice oxygen intensify the dissolution of active species. Herein, we overcome this challenge by constructing the NiFe hydroxide/Ni 4 Mo alloy (NiFe-LDH/Ni 4 Mo) heterojunction electrocatalyst, featuring the Ni 4 Mo alloy as the oxygen pump to provide oxygenous intermediates and electrons for NiFe-LDH. The released lattice oxygen can be timely offset by the oxygenous species during the LOM process, balancing the regeneration of lattice oxygen and assuring the enhancement of the durability. In consequence, the durability of NiFe-LDH is significantly enhanced after the modification of Ni 4 Mo with an impressive durability for over 60 h, much longer than that of NiFe-LDH counterpart with only 10 h. In situ spectra and first-principle simulations reveal that the adsorption of OH − is significantly strengthened owing to the introduction of Ni 4 Mo, ensuring the rapid regeneration of lattice oxygen. Moreover, NiFe-LDH/Ni 4 Mo-based anion exchange membrane water electrolyzer (AEMWE) presents an impressive durability for over 150 h at 100 mA cm −2 .

Beyond PET imaging, BBPA is a theranostic agent for boron neutron capture therapy (BNCT). Because BBPA possesses an identical chemical structure to BNCT and PET, it can potentially predict the boron concentration for BNCT using [ 18 F]BBPA-PET. The synthesis of BBPA was achieved by selectively fluorinating the α-aminoborate compound, taking advantage of the varying rates of solvolysis of the B−F bond. The study showcased the high-contrast [ 18 F]BBPA-PET imaging in various tumor models, highlighting its broad applicability for both [ 18 F]BBPA-PET and BBPA-BNCT. [ 18 F]BBPA-PET tumor uptake remains consistent across various doses, including those used in BNCT. This enables accurate estimation of the boron concentration in tumors using [ 18 F]BBPA-PET. With its dual boron structure, BBPA increases boron concentration in tumor cells and tumor tissues compared to BPA. Thus, less boron carrier is needed.

  @article{ , abstract = {Contact Electro-Catalysis (CEC) using commercial dielectric materials in contact-separation cycles with water can trigger interfacial electron transfer and induce the generation of reactive oxygen species (ROS). However, the inherent hydrophobicity of commercial dielectric materials limits the effective reaction sites, and the generated ROS inevitably undergo self-combination to form hydrogen peroxide (H 2 O 2 ). In typical CEC systems, H 2 O 2 does not further decompose into ROS, leading to suboptimal reaction rates. Addressing the generation and activation of H 2 O 2 is therefore crucial for advancing CEC. Here, we synthesized a catalyst by loading the dielectric material polytetrafluoroethylene (PTFE) onto ZSM-5 (PTFE/ZSM-5, PZ for short), achieving uniform dispersion of the catalyst in water for the first time. The introduction of an Fe III -initiated self-cycling Fenton system (SF-CEC), with the synergistic effects of O 2 activation and Fe III -activated H 2 O 2 , further enhanced ROS generation. In the Fe III -initiated SF-CEC system, the synergistic effects of ROS and protonated azo dyes enabled nearly 99 % degradation of azo dyes within 10 minutes, a sixfold improvement compared to the CEC system. This represents the fastest degradation rate of methyl orange dye induced by ultrasound to date. Without extra oxidants, this system enabled stable dissolution of precious metals in weakly acidic solutions at room temperature, achieving 80 % gold dissolution within 2 hours, 2.5 times faster than similar CEC systems.

Notably, the immune microenvironment of the lungs is naturally enriched with alveolar macrophages (AMs). Herein, we introduce a novel nebulized magnetothermal immunotherapy strategy to treat orthotopic lung cancer by using magnetothermal nanomaterial (Zn−CoFe 2 O 4 @Zn−MnFe 2 O 4 −PEG, named ZCMP), which can release iron ions via an acid/thermal-catalytic reaction to maximize the use of lung‘s immune environment through the cascade activations of AMs and natural killer (NK) cells.

Using the xHTL/HaloTag7 labeling system, we measure the ligand-induced activation kinetics of the epidermal growth factor receptor (EGFR) in single living cells.

Currently, the pursuit of single-component neutral thermoelectric materials without exogenous doping presents a compelling alternative.

This intrinsically planar chiral switch can not only undergo thermal or photochemical E/Z isomerization but can also be reversibly and quantitatively oxidized to both a monocationic and a dicationic state which is associated with significant changes in its (chir)optical properties.

Here, we propose a light-responsive G4-binder for precise modulation of drug activation, providing dynamic and spatiotemporal control over G4-associated biological processes contributing to cancer cell death. We developed a specialized fluorinated azobenzene (AB) switch equipped with a quinoline unit and a positively charged carboxamide side chain, Q-Azo4F-C , designed for targeted binding to G4 structures within cells. Biophysical studies, combined with molecular dynamics simulations, provide insights into the unique coordination modes of the photoswitchable ligand in its trans and cis configurations when interacting with G4s. The observed variations in complexation processes between the two isomeric states in different cancer cell lines manifest in more than 25-fold reversible cytotoxic activity. Immunostaining conducted with the structure-specific G4 antibody (BG4), establishes a direct correlation between cytotoxicity and the varying extent of G4 induction regulated by the two isoforms. Finally, we demonstrate the photo-driven reversible regulation of G4 structures in lung cancer cells by Q-Azo4F-C . Our findings highlight the potential of light-responsive G4-binders in advancing precision cancer therapy through dynamic control of G4-mediated pathways.}, archive = {J_ANGEW}, author = {Marta Dudek and Lucía López-Pacios and Nasim Sabouri and Juan J.

  @article{ , abstract = {Aqueous zinc (Zn) batteries are highly desirable for sustainable and large-scale electrochemical energy storage technologies. However, the ceaseless dendrite growth and the derived dead Zn are principally responsible for the capacity decay and insufficient lifespan. Here, we propose a dissolved oxygen-initiated revitalization strategy to reactivate dead Zn via ferrocene redox chemistry, which can be realized by incorporating a trace amount of poly(ethylene glycol) as a solubilizer to improve the solubility of water-insoluble ferrocene derivatives. Ferrocene scaffold can be spontaneously oxidized to ferricenium cations by dissolved oxygen, which eradicates the dissolved oxygen-involved Zn corrosion and insulating by-product generation. Subsequently, the generated ferricenium cations as the scavenger can rejuvenate electrically isolated dead Zn into electroactive Zn 2+ ions to compensate the zinc loss.

The molecules with three-dimensional complexity hold a greater probability to improve clinical outcomes, solubility, selectivity for target proteins, and metabolic stability.

In principle, the dearomative functionalization of N -heteroarene allows for the conversion of readily available planar molecules into partially or fully saturated nitrogen heterocycles, which are most significant structural motifs of pharmaceuticals and natural products. Unfortunately, these reactions are very rare because of the inherent challenge imposed by heteroarenes’ poor reactivity, rendering the process thermodynamically unfavorable. Herein, we report a modular approach for accessing 3D chemical space in translating planar heteroarenes into valuable 3D heterocycles via the installation of a highly versatile cyano group as a new vector. This approach is enabled by the in situ generation of reactive, non-symmetric iodane by combining cyanide anion and bench-stable PhI(OAc) 2 .

The red-shifted photoluminescence (PL) stems from a combination of the external heavy atom effect and the formation of emissive clusters centered around electron-rich sulfur atoms. Furthermore, the dopants enhance exciton generation efficiency and facilitate energy transfer from smaller PAI units to larger aggregates, leading to dramatically increased Φ p . This strategy proves universal, opening possibilities for acquiring long-wavelength RTP with tunable photophysical properties.

This study provides a new methodology of nanocatalytic antioxidation for treating ALI and other hepatic diseases related to oxidative stress.}, archive = {J_ANGEW}, author = {Di Jiang and Bowen Yang and Jianlin Shi}, doi = {10.1002/anie.202412031}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {1}, pages = {e202412031}, shortjournal = {Angew.

  @article{ , abstract = {Although micron-sized microgels have become important building blocks in regenerative materials, offering decisive interactions with living matter, their chemical composition mostly significantly varies when their network morphology is tuned. Since cell behavior is simultaneously affected by the physical, chemical, and structural properties of the gel network, microgels with variable morphology but chemical equivalence are of interest. This work describes a new method to produce thermoresponsive microgels with defined mechanical properties, surface morphologies, and volume phase transition temperatures. A wide variety of microgels is synthesized by crosslinking monomers or star polymers at different temperatures using thermally assisted microfluidics. The diversification of microgels with different network structures and morphologies but of chemical equivalence offers a new platform of microgel building blocks with the ability to undergo phase transition at physiological temperatures.

  @article{ , abstract = {Electrochemical imaging enables an in-depth analysis of the interface heterogeneity and reaction kinetics of single entities. However, electrode passivation during electrochemical reactions decreases the active sites and harms the long-term stability. Here, we introduce a method using laser-induced photothermal effects to restore the electrochemical activity, which is particularly displayed as enhanced micrometric patterns in electrochemiluminescence (ECL) microscopy. By co-localization characterization and X-ray photoelectron spectroscopy (XPS), the mechanism of active site regeneration is validated as the removal of the oxide film for restoring the local surface ECL reactivity under laser irradiation. The surface-confined and voltage-dependent features of ECL allows for easy pattern erasure and rewriting, and it shows good reversibility and anti-counterfeiting potential. This approach overcomes the passivation processes, evidently improves the image quality of single biological entities including Shewanella bacteria and cells, and makes the subtle contour structures more distinct. The renewable electrode interface also enhances the ECL signal of model bead-based bioassays. This approach not only showcases precise control in fabricating micron patterns but also holds promise for enhancing the sensitivity in electrochemical immunoassays and bioimaging.}, archive = {J_ANGEW}, author = {Xiaodan Gou and Zejing Xing and Zhichen Zhang and Rong Jin and Qin Xu and Neso Sojic and Jun-Jie Zhu and Cheng Ma}, doi = {10.1002/anie.202410825}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {1}, pages = {e202410825}, shortjournal = {Angew.

  @article{ , abstract = {Lithium metal batteries (LMBs) have become a hot topic in the research of next-generation advanced battery technology due to their high specific energy. However, the high reaction activity between lithium metal and electrolyte is considered one of the key bottlenecks limiting large-scale applications of LMBs. As a classic electrolyte additive, lithium nitrate (LiNO 3 ) significantly improves the stability of lithium metal in ether-based electrolytes. However, its solubility in carbonate-based electrolytes widely used in lithium-ion batteries is extremely low, causing limited protective capability on lithium metal, which has become a key obstacle to the commercial application of lithium metal batteries. Here, we enhanced the local negative charge density of carbonyl oxygen atoms in carbonate molecules by introducing electron donors, making it easier for them to coordinate with Li + , thereby weakening the interaction between Li + and NO 3 − , and significantly increasing the solubility of LiNO 3 in ester electrolytes. The modified ester solvent promotes the derivatization and decomposition of salt anions, leading to the formation of a dense SEI layer rich in LiF and LiN x O y . This significantly improves the stability of lithium metal in ester-based electrolytes.

  @article{ , abstract = {Ultra-fast magic-angle spinning (100+kHz) has revolutionized solid-state NMR of biomolecular systems but has so far failed to gain ground for the analysis of paramagnetic organic and inorganic powders, despite the potential rewards from substantially improved spectral resolution. The principal blockages are that the smaller fast-spinning rotors present significant barriers for sample preparation, particularly for air/moisture-sensitive systems, and are associated with low sensitivity from the reduced sample volumes. Here, we demonstrate that the sensitivity penalty is less severe than expected for highly paramagnetic solids and is more than offset by the associated improved resolution. While previous approaches employing slower MAS are often unsuccessful in providing sufficient resolution, we show that ultra-fast 100+kHz MAS allows site-specific assignments of all resonances from complex paramagnetic solids. Combined with more reliable rotor materials and handling methods, this opens the way to the routine characterization of geometry and electronic structures of functional paramagnetic systems in chemistry, including catalysts and battery materials.

  @article{ , abstract = {Excessive activation of the stimulator of the interferon gene (STING) pathway has been identified as a significant contributor to various autoimmune diseases, such as STING-associated vasculopathy with infantile-onset (SAVI) and inflammatory bowel disease (IBD). However, discovering effective STING antagonists for treating STING-mediated autoimmune disorders remains challenging. Herein, we identified the natural product anhydrotuberosin (ATS) as a potent STING antagonist by a high-throughput chemical screen and follow-up biological validations. However, the limited supply from natural product isolation impeded the pharmacological evaluations of ATS. Accordingly, we developed a concise and scalable total synthesis of ATS in 6 steps. Enabled by total synthesis, we further extensively investigated ATS's mode of action and evaluated its therapeutic potential. Remarkably, ATS inhibits STING signaling in PBMCs derived from three SAVI patients. ATS showed decent pharmacokinetic parameters and strongly alleviated tissue inflammation in DSS-induced IBD colitis and Trex1 -/- autoimmune animal models with low toxicity. Collectively, this research lays the foundation for developing novel STING antagonists as an effective therapy for autoinflammatory and autoimmune diseases.}, archive = {J_ANGEW}, author = {Fusheng Guo and Jing Zhang and Yihui Gao and Zhou Shu and Fei Sun and Jing Ma and Xu Zhou and Wenyang Li and Huawei Mao and Xiaoguang Lei}, doi = {10.1002/anie.202407641}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {1}, pages = {e202407641}, shortjournal = {Angew.

In particular, his work on organometallic mixed catalysts, which allows the polymerization of ethylene at normal pressure, led to a revolution in plastics production and changed the everyday life of all mankind. In 1963, he was awarded the Nobel Prize in Chemistry for this work, together with Giulio Natta. This article focuses on Ziegler's early career, which has received little attention to date. It describes his youth and study years in Marburg, which partly coincide with the First World War. Subsequently, his postdoctoral period is examined, which led him via Marburg and Frankfurt to his first associate professorship in Heidelberg. Special attention is paid to his relationship to National Socialism, which he opposed. As a result, Ziegler experienced professional difficulties in the 1930s, such as repeated rejection when filling various professorships. His appointment as a full professor in Halle and his subsequent directorship at the Max-Planck-Institut für Kohlenforschung (Coal Research), where he finally achieved his greatest research achievement, are described in the following.}, archive = {J_ANGEW}, author = {Christoph Kießling}, doi = {10.1002/anie.202403180}, journal = {Angewandte Chemie International Edition}, month = {1}, number = {1}, pages = {e202403180}, shortjournal = {Angew.
